The importance of preventing corrosion in industry
Corrosion is one of the greatest enemies of metal components used in industrial environments. It is a natural process which, if left unchecked, can seriously undermine the integrity of components, structures and machinery, directly affecting a company’s productivity and profitability.
In sectors such as automotive, aerospace, steelmaking or capital goods manufacturing, metal products are exposed to conditions that accelerate deterioration: humidity, salinity, temperature fluctuations, atmospheric pollution or extended storage periods. The direct consequence of this exposure is a loss of functionality, economic value and reliability of the affected materials.
Preventing corrosion is not simply a matter of appearance. The formation of a small spot of corrosion can, over time, spread beneath protective coatings, affect joints or undermine the dimensional accuracy of metal components.
The oxidation of a metal piece can pose safety risks by causing structural or mechanical failures, logistical delays or even the return of products by customers, with a subsequent impact on the supplier’s reputation. Furthermore, the economic cost of replacing, reworking or refurbishing components can multiply the initial packaging cost if an appropriate solution is not implemented from the outset.
Economic and operational impact of corrosion in industrial sectors
Studies show that corrosion has a global economic impact of more than 3% of world GDP. In the industrial sector, this translates into millions of Euros in direct and indirect losses each year. Prevention therefore becomes a strategic investment – not only to safeguard the value of components, but also to guarantee production continuity, avoid commercial complaints and assure customer satisfaction.
What is corrosion and how does it affect metal materials?
Corrosion is a chemical or electrochemical reaction between a material – typically metal – and its environment, which results in gradual deterioration. It is a natural process by which metals revert to their original form, the ore from which they were extracted, in order to achieve a more stable state.
For example:
- Iron exposed to moisture and oxygen forms iron oxide (rust), a brownish-red deposit.
- Copper develops a greenish patina of copper carbonate.
- Aluminium may form a whitish layer of alumina.
In some cases this oxide layer can provide partial protection to the underlying metal (such as alumina on aluminium), but in most cases corrosion degrades the mechanical and aesthetic properties of the metal, weakening it and rendering it unsuitable for its intended function.
This phenomenon poses a critical threat in industrial settings, as it undermines the structural integrity of components and equipment. That is why understanding the mechanisms of corrosion and the factors that accelerate it is key to applying effective protective solutions.

Common types of corrosion
Although many forms of corrosion exist, they are typically classified into two main categories: uniform and localized.
- General or uniform corrosion: this occurs evenly across the exposed metal surface, causing a gradual thinning. It is the most predictable and controllable form of corrosion.
- Localized corrosion: this develops in specific areas and can cause severe damage in a short period. The main variants include:
- Galvanic corrosion: occurs when two dissimilar metals are in contact in the presence of moisture or a conductive liquid. The less noble metal reacts first and deteriorates faster.
- Pitting corrosion: small, deep holes form on the metal’s surface. It is hard to detect and highly aggressive.
- Crevice corrosion: develops in gaps, joints or hard-to-reach areas where moisture or dirt accumulates, creating aggressive micro-environments.
- Cavitation corrosion: occurs in moving fluids, such as in hydraulic systems, due to the formation and collapse of vapour bubbles that damage the metal surface.
- Microbial corrosion: this is driven by microbial activity, where certain microorganisms produce corrosive chemicals.
Some forms can combine physical and electrochemical mechanisms:
- Stress corrosion: occurs when a metal under mechanical stress is exposed to a corrosive medium, causing cracks or fractures.
- Fretting or contact corrosion: associated with the movement of metal components against each other under humid conditions, removing protective layers and exposing the metal.
Oxidation vs. corrosion: is there a difference?
Oxidation is often confused with corrosion, but they are not exactly the same. Technically, oxidation is a form of corrosion that occurs at high temperatures when metal reacts directly with oxygen or sulphur. This produces a layer of oxide on the surface – rust – which under certain conditions can act as a protective barrier. However, oxidation is a specific process and should be distinguished from other forms of corrosion.
Classification of metals in the galvanic series
The galvanic series is a ranking that orders metals by their tendency to corrode when in contact with another metal in the presence of an electrolyte, such as saline water. The scale runs from the most reactive (least noble) to the most resistant (most noble).
For example, magnesium, zinc or aluminium are at the bottom of the series, reflecting their high reactivity. Copper, silver or gold, on the other hand, are much more resistant to corrosion.

When two dissimilar metals come into direct contact and there is moisture or a conductive liquid present, the more reactive (or less noble) metal corrodes faster. This phenomenon, called galvanic corrosion, underscores the importance of choosing compatible materials for industrial structures, automotive components or specialised packaging.
A clear example of galvanic corrosion in industrial packaging occurs when an aluminium piece is packed alongside metal components such as steel staples or placed in contact with metal racks. If moisture is present, the aluminium, being less noble, starts to corrode in the areas of contact. This is particularly relevant in packaging for maritime transport or under conditions of high humidity.
Factors that accelerate corrosion
The rate and severity of corrosion depend on a range of factors. The most important include:
- Environmental humidity: water acts as a conductive medium for the electrochemical reactions that undermine metal.
- Presence of salts: particularly sodium chloride in marine environments or during sea transport, which catalyses the corrosion process.
- Elevated temperature: speeds up chemical reactions and can promote the condensation of moisture in vulnerable areas.
- Atmospheric contaminants: gases such as sulphur dioxide or nitrogen oxides contribute to the formation of acidic conditions that attack metal.
- Storage and transport conditions: metal components stored without proper protection or packaging may be exposed to cycles of humidity, dust and contaminants.
Together, these factors make a well-planned protective strategy essential – from the moment of packaging through to the final destination of the product.
Anticorrosive protection methods: evolution and comparison
Over time, industry has adopted various solutions to protect metal components against corrosion. From basic coatings to more advanced technologies, the choice of method depends on the metal, its application and the environment it will be exposed to.
Below we review the main approaches, their evolution and their pros and cons.
Traditional solutions (oils, greases, paints)
For decades, the most frequently used protective systems were physical coatings applied directly to the metal surface to create a barrier against moisture, oxygen and other corrosive agents.
Some of the most representative methods include:
- Anticorrosive oils: these create a water-repellent oily layer that temporarily protects the metal surface. Application can be by dipping, spraying or brush, and they provide instant protection.
However, complete coverage is required, the oily surface can attract dirt and must be removed prior to operations such as painting or welding, which involves the use of solvents and waste disposal. Furthermore, their protective effects diminish over time and application tanks require specialised maintenance. - Protective greases: these are thick and persistent compounds, suitable for long storage periods or severe conditions. They effectively protect against humid environments, but their removal requires chemicals, adding time and cost to preparation.
- Antirust paints and temporary coatings: applied directly to metal components for storage or transport. They include industrial enamels, inhibitor-rich primers or peelable lacquers. Some older formulations contained chromates or nitrites – now restricted due to health and environmental impacts. Although these coatings provide additional protection, their application and removal add process steps and reduce logistical efficiency.
- Resin and industrial enamel coatings: used when a durable surface finish is required. Nevertheless, these are not viable for temporary packaging or for components needing immediate assembly afterwards.
- Airtight packaging with desiccants: this involves sealing the metal product in a closed environment (such as a plastic sleeve or bag) alongside desiccant bags such as clay or silica gel sachets. The aim is to maintain a dry atmosphere to avoid oxidation. The method’s effectiveness depends on a perfect seal and a low residual humidity. If oxygen enters or there are gaps, the risk of corrosion persists. Furthermore, the desiccant’s ability to absorb moisture is limited and drops once it reaches its absorption capacity.
These methods, while still applicable in certain contexts, present clear limitations in terms of operational efficiency, sustainability and adaptability to the current requirements of industry. Furthermore, their protective ability depends largely on proper application and the condition of the surface prior to coating.
Limitations of these methods in modern logistics
Traditional protective methods – oils, greases or paint – have been viable for decades. But with the evolution of industrial and logistical processes, these methods present significant limitations when addressing the sector’s current needs.
- Manual and inefficient application: their use typically requires skilled workers and drying or cleaning periods, slowing operations. Furthermore, removal afterwards adds additional cost in chemicals and waste disposal.
- Poor compatibility with automated processes: oily surfaces can affect sensors, automated vision systems or robotic operations, making their integration into modern production lines more challenging.
- Uneven coverage on complex components: components with cavities, irregular geometry or hard-to-reach areas may remain exposed, increasing the risk of localized corrosion.
- Environmental and regulatory risks: many traditional products contain solvents or compounds with VOCs (volatile organic compounds), making it more difficult to comply with legislation such as REACH, RoHS or TRGS 615.
- Sustainability implications: oils and greases often require non-recyclable packaging, generate hazardous waste and necessitate additional cleaning processes, all adding to their environmental footprint.
In sectors where quality, efficiency and traceability are key – such as automotive, aerospace or steel – these limitations result in additional operational cost and a risk of non-compliance in international shipments or long storage periods, prompting companies to move towards more modern alternatives.
Modern solutions: packaging with volatile corrosion inhibitors (VCI)
Packaging materials featuring VCI (volatile corrosion inhibitor) technology represent a significant advance in anticorrosive protection. VCI has become a more effective, clean and adaptable solution for industrial logistics.
The use of VCI packaging traces back to the mid 20th century, when nitrite-impregnated papers were first introduced, and it has since evolved into a more sophisticated, safer and environmentally friendly solution free from hazardous compounds and compliant with REACH, RoHS and TRGS 615.
This technology, based on amine nitrites, particularly dicyclohexylamine nitrite (known as “Dichan”), originally appeared in military applications, where a reliable solution was required to protect metal components and structures.
Other nitrites commonly used in industrial corrosion inhibitor formulations include sodium nitrite and calcium nitrite. Sodium nitrite is an anodic inhibitor and provides effective protection for ferrous metals; however, it can pose health and safety risks and is now largely being replaced by more advanced, environmentally friendly alternatives.
Amines, compounds derived from ammonia, have also been used in some VCI formulations. However, due to their strong smell, causticity and health risks (such as skin, eye and respiratory irritation), their use is declining in favour of less hazardous compounds.
Over time, VCI technology has been adopted across industries, particularly in automotive and heavy machinery, where traditional methods were cumbersome or insufficient. As requirements for traceability, sustainability and logistical efficiency have grown, VCI has kept pace by extending into new materials, carriers and industrial applications.
In contrast to physical methods (such as greases or oils), VCI compounds do not need to be directly applied to the metal surface. This makes it possible to protect hard-to-reach areas, internal cavities and complex components.
Today, VCI is incorporated into a range of packaging materials as sleeves and bags, sheets and film, foam and emitters, and is applicable to a variety of materials, predominantly paper and plastic.
For sectors with stringent requirements for quality and traceability – such as automotive, aerospace, defence or energy – VCI packaging has become a key protective tool, particularly for international shipments, long storage periods or challenging environmental conditions.
VCI technology: what is it and how does it protect against corrosion?
VCI technology (volatile corrosion inhibitor) has revolutionised the protection of metals in industrial environments thanks to its effectiveness, cleanliness and ease of integration into logistical processes.
Unlike traditional coatings that act as physical barriers, VCI offers an active and non-invasive chemical solution that adapts to components of any geometry, even in conditions of humidity and the presence of oxygen.

Definition and function of volatile corrosion inhibitors
Volatile corrosion inhibitors (VCI) are chemical compounds designed to protect metal surfaces through an active physico-chemical process that takes place in the vapour phase. They work by volatilising from a solid carrier (such as paper, film, foam or an emitter) and diffusing throughout a sealed space, such as a bag, sleeve or crate.
Once released, the VCI molecules migrate through the air as vapour until they reach the metal surfaces inside the packaging. There they adsorb – that is, they temporarily bond – to the metal, forming an invisible molecular layer that acts as a protective barrier against corrosive agents.
This protective layer serves several complementary functions:
- Blocks electrochemical oxidation: by attaching to the metal surface, VCI molecules interrupt the electron flow required for the redox reaction between metal, oxygen and water, preventing the formation of oxides and other corrosive products.
- Displaces moisture: by altering the immediate microenvironment of the metal, the VCI layer reduces water activity and prevents condensation on the surface – a key catalyst of corrosion.
- Neutralises contaminants: many VCI formulations are designed to react with acidic residues, sulphides, chlorides or industrial gases present in the environment, reducing their corrosive potential on sensitive metals.
This process is reversible and non-invasive. When the packaging is opened, the VCI molecules gradually dissipate without leaving residues or altering the properties of the protected component. This means the part can be handled, assembled or processed straight away – no cleaning is required, unlike with other anticorrosion methods such as oils or solid coatings.
The effectiveness of the system depends on several factors, including:
- the type and concentration of VCI used,
- the volume of the sealed space,
- the exposed metal surface area,
- the airtightness of the packaging, and
- external environmental conditions (temperature, relative humidity, etc.).
In a properly sealed and dimensioned environment, VCIs can maintain a stable protective atmosphere for several months and in some cases over a year, making them an effective solution for long-term storage, maritime export or use in aggressive climates.
Originally developed for military and aerospace applications, this technology has become a benchmark solution in sectors such as automotive, steel, precision engineering, aerospace or electronics, where reliable anticorrosive packaging is critical.
Advantages of VCI over traditional methods
The use of volatile corrosion inhibitors in industrial packaging offers clear advantages over traditional methods based on oils, greases or solid coatings.
The key benefits include:
- Cleanliness and direct handling: components protected with VCI require no degreasing, washing or additional preparation before assembly or final use. This saves handling time, reduces operational costs and lowers the risk of contamination during subsequent production phases.
- Complete protection, even in complex areas: VCI molecules diffuse in vapour form, reaching all metal surfaces, including internal cavities, threads, holes and complex geometries. This ensures uniform protection without the need for direct application or physical contact.
- Compatibility with automated processes: as they leave no greasy residue or visible coating, VCI materials do not interfere with sensors, vision systems or robotic operations. This makes them particularly suitable for integration into high-precision automated production lines.
- Greater safety for warehouse workers and the environment: modern VCIs are formulated without nitrites, chromates or other hazardous substances. They comply with European standards such as REACH, RoHS and TRGS 615, minimising health risks and environmental impact compared to traditional products containing solvents, oily residues or non-recyclable packaging.
- Ease of application and suitability for long-term storage: VCI carriers (such as paper, film, sleeves or emitters) are quick and easy to apply. Their effectiveness is maintained over long periods as long as the packaging remains properly sealed. This durability makes them ideal for long-distance exports, prolonged storage or demanding climatic conditions.
Types of anticorrosive packaging materials
VCI packaging materials come in a range of forms, weights and formats, offering great versatility to match different logistical requirements. Depending on the type of component, storage duration, environmental conditions and handling needs, specific solutions can be selected to optimise both anticorrosive protection and operational efficiency.
In this section we review the main industrial anticorrosive packaging materials available on the market: VCI paper, VCI plastic, stretch film, VCI woven fabric and other complementary products such as desiccants or bubble film. All of them incorporate volatile corrosion inhibitors that become active upon contact with air in a closed space, protecting both ferrous and non-ferrous metals without the need for additional oils or coatings.
VCI paper
VCI paper is one of the most frequently used materials in industrial anticorrosive packaging due to its versatility, ease of use and cost-efficiency. Made from kraft paper impregnated with volatile corrosion inhibitors (VCI), it emits molecules that deposit on metal components to form an invisible protective layer, preventing oxidation without the need for greases or oils.
Handling is similar to that of traditional packaging paper, but with active protective properties integrated into it. It can be used in manual or semi-automated processes and is particularly recommended for protecting small or medium-sized components during transport or storage.
Main types of VCI paper available:
- Plain kraft VCI paper: the standard solution for direct wrapping or for separation between layers in large packaging.
- Plastic-coated VCI paper: adds a barrier against moisture, making it ideal for more challenging environmental conditions.
- VCI paper tube: preformed to wrap elongated components such as profiles, tubes or shafts.
- VCI crepe paper: with a crinkled structure designed to wrap irregular or fragile components.
- Plastic-coated VCI crepe paper: combines flexibility and resistance, making it suitable for export or long-term storage.
These paper anticorrosive packaging solutions can be tailored to suit logistical processes, the nature of the components and storage conditions.
VCI plastic: bags, sheets and tubes
VCI plastic is a highly effective solution for protecting metal components against corrosion during storage or transport. Manufactured from polyethylene with volatile corrosion inhibitors incorporated during the extrusion process, this material slowly releases active molecules that form a protective layer on the metal, even in hard-to-reach areas such as internal cavities or components with complex geometry.
In addition to acting as a chemical barrier, VCI plastic physically protects components from dust and external moisture. Its transparency allows for quick visual inspection, its flexibility makes it adaptable to a range of shapes, and by eliminating the need for protective oils or greases, it improves logistical efficiency and reduces cleaning costs.
Main formats of VCI plastic available:
- VCI bags, ready to use and available in a range of sizes. Ideal for individual components or small batches.
- VCI sheets: pre-cut film, used as an intermediate layer or flexible wrapper.
- VCI plastic in rolls: suitable for continuous packaging or automated production lines.
- VCI plastic tube: perfect for efficiently and safely packaging elongated components.
All the formats offered by Inviker are 100% recyclable and can be customised in dimensions, thickness and colours according to technical requirements.
In our post on VCI plastic formats we provide a detailed analysis of the characteristics of each option, their recommended applications and how to select the most suitable format according to the components and their logistical environment.
VCI stretch film
Stretch film with volatile corrosion inhibitors (VCI) is a technical packaging solution that combines two essential functions for industry: anticorrosive protection and secure load containment. This material, manufactured from film treated with VCI agents, makes it possible to wrap metal components while releasing a protective atmosphere that inhibits oxidation.
Usually made from polyethylene (PE), this film is applied in the same way as conventional stretch film directly to individual components, assemblies or palletised loads and integrates easily into existing logistics processes, whether manually or automatically. It encloses the load by adhering to itself due to its elasticity. This makes it a more efficient alternative to traditional methods such as oiled papers, protective coatings or other more complex anticorrosive systems, reducing both processing time and material usage.
During wrapping, the film emits VCI molecules that deposit on the metal surface, creating an invisible, dry protective layer. The result is clean, compact and highly functional packaging.
For example, a manufacturer of steel components can stack the parts on a pallet, wrap them in VCI stretch film and achieve a complete solution that guarantees corrosion protection during transport without adding additional materials or steps to the packaging process. This versatility and speed make VCI stretch film particularly valued in industrial settings with large production volumes and frequent dispatches.
Benefits of VCI stretch film
From an operational and logistical perspective, VCI stretch film offers clear benefits for production managers and purchasing departments:
- Rapid and clean application: compatible with automatic wrapping machines or manual application, without generating additional waste or requiring drying time.
- Reduction in auxiliary materials: a single material performs a dual function of containment and anticorrosive protection, reducing packaging complexity and eliminating the need for papers, oils or secondary packaging.
- Space and weight savings: the film conforms to the shape of the load, adding no additional bulk and reducing total weight in comparison to rigid or closed packaging.
- Content visibility: its transparency allows for visual inspection without needing to break the packaging.
- Consistent, uniform protection: VCI diffusion guarantees coverage, even in internal spaces or hard-to-reach areas.
- Operator safety: free from nitrites and hazardous compounds. It meets European standards such as TRGS 615, RoHS and REACH.
- Sustainability: 100% recyclable, with versions available in various proportions of recycled content. By avoiding additional oils and chemicals, it reduces hazardous waste.
These characteristics make VCI stretch film a key tool for streamlining processes, cutting costs and raising protective standards in industrial packaging.
Industrial applications
VCI stretch film is widely used in sectors where metal components need to be kept free from corrosion during transport or temporary storage. The most common applications include:
- Palletisation of metal sub-assemblies in the automotive industry, allowing protective packaging of machined components ready for assembly, such as gears, brackets or shafts.
- Protection of long profiles and metal tubes: spiral-wrapping with VCI film guarantees complete coverage of products that do not fit into conventional packaging.
- Irregular-shaped industrial components: the film adapts to components with complex geometry such as welded frames, forged parts or assemblies providing effective coverage.
- Mixed loads with metal content: ideal for production lines with combined products, where metal components require specific protective measures against corrosion.
Types of VCI stretch film available at Inviker
At Inviker we offer various options of VCI stretch film tailored to your machinery, transport requirements and product characteristics:
- Standard VCI stretch film: a versatile, general-purpose solution, suitable for manual or automatic applications with medium-demand conditions.
- VCI Plus300 stretch film: a high-performance film designed for automatic wrapping lines. It guarantees a 300% stretch and high tearing resistance. Ideal for heavy loads or components with irregular profiles that require greater tension without compromising material integrity.
- VCI mesh-reinforced stretch film: integrates a reinforcing mesh to provide additional resistance against perforation and tearing. Especially useful for components with protruding elements or in challenging logistical conditions where a more robust film is required.
VCI woven fabric
VCI woven fabric is a technical material that combines the mechanical strength of woven fabric with the active chemical protection provided by volatile corrosion inhibitors. This type of packaging offers a particularly effective solution for heavy, bulky or complex-shaped metal components, especially in challenging logistical conditions where durability, flexibility and resistance are required.
Made from woven polypropylene (PP) or polyethylene (PE), VCI woven fabric is impregnated during production with inhibitor compounds. These molecules are progressively released once the packaging is closed, filling the enclosed space with an anticorrosive atmosphere that protects exposed metal surfaces. As a result, oxidation is avoided without the need to apply protective oils or perform subsequent cleaning.
Thanks to its woven structure, the anticorrosive woven fabric offers outstanding resistance to tearing, perforation and abrasion, even when frequently handled or during international transport. Furthermore, its flexibility allows it to conform to the contours of components, and its lightness helps reduce packaging weight without compromising robustness.
Formats available and handling at Inviker
At Inviker we supply VCI woven fabric in a range of formats to facilitate its use in industrial applications:
- Rolls of VCI woven fabric for cutting to size as required, ideal for manual or semi-automated operations. Allows the production of custom wrappings, covers or protective sheets.
- Covers made from VCI woven fabric tailored to dimensions of specific components or palletised loads. Ready for direct application.
- Pre-cut woven fabric sheets cut to convenient sizes to streamline daily operations.
The woven fabric can be closed by stitching, heat sealing, adhesive tape or staples, depending on the load and expected exposure. It is easy to handle and fully compatible with packaging processes in production facilities or for export.
Industrial applications and recommended sectors
VCI woven fabric is particularly suitable for protecting metal components in industries with high resistance and durability requirements:
- Moulds, tooling and large machined components in sectors such as automotive, aerospace or heavy metalworking.
- Metal coils, sheets, tubes or welded structures where flexible and robust packaging is required alongside anticorrosive properties.
- Palletised loads of irregular or large components that do not conform to standard covers.
- Outdoor storage or maritime export, often combined with desiccants to reinforce moisture protection.
Protection and additional benefits
The anticorrosive protection provided by VCI woven fabric is as effective as that offered by other materials treated with volatile corrosion inhibitors. The active molecules diffuse from the fabric into the enclosed space, uniformly protecting metal surfaces.
Due to the larger volumes typically involved in using woven fabric, it is often desirable to combine it with VCI emitters or desiccant bags to help maintain a protective atmosphere.
Key advantages of VCI woven fabric use in industrial packaging:
- Dual function: combines anticorrosive VCI protection and high mechanical resistance.
- Strength and flexibility: adapts to complex shapes without tearing.
- Impermeability: provides an effective barrier against dust, water and contaminants.
- Lightness: a thinner, lighter alternative to heavy gauge plastic film.
- Recyclable: a sustainable packaging solution at the end of its service life.
Due to its balance of robustness, effective corrosion protection and sustainability, VCI woven fabric is a highly valued solution for industrial logistics operations that require maximum protection alongside cost-efficiency and waste reduction.
VCI bubble wrap
The plastic bubble wrap with VCI treatment is a technical material that combines active anticorrosive protection and physical cushioning in a single product. By incorporating volatile corrosion inhibitors (VCI) into its structure, this air-cushioned film protects metal components against oxidation and impact, optimising time, cost and logistical efficiency.
It consists of a structure of small air-filled bubbles encapsulated between two layers of plastic, with an additional polyethylene (PE) layer treated with VCI. This combination means that, once the packaging is closed, inhibitor molecules are released and form an invisible protective layer on metal surfaces, while the air bubbles act as a shock absorber against knocks, abrasions and vibrations during transport or storage.
In addition to physical and chemical protection, this film provides slight thermal insulation: its air-cushioned structure dampens the effects of abrupt temperature fluctuations, reducing the risk of condensation on metal components. The bubble film retains a degree of transparency, allowing for visual inspection without opening the package.
From an operational standpoint, VCI bubble wrap cuts packaging time by serving a dual purpose – protective wrapping and anticorrosive treatment in a single material. It also avoids the need for multiple overlapping materials, contributing to more sustainable logistics by reducing waste. All the material is recyclable at the end of its service life.
Formats available
At Inviker we supply VCI bubble wrap in standard rolls, easily adaptable to different requirements. The material can be cut to size directly at the packaging workstation and used as a wrapper, separator or protective padding.
It is easy to handle and can be combined with other packaging elements, such as boxes or crates, to provide additional protection.
Industrial applications and recommended sectors
VCI bubble wrap is particularly suitable for industrial sectors where both shock absorption and oxidation protection are required.
- Automotive: for components such as engine parts, body components and electronic systems.
- Electronics: for printed circuits, sensors, measuring and control equipment.
- Industrial machinery: for spare parts, metal tools and mechanical assemblies.
- Hardware: for screws, fittings, hand tools and loose metal components.
It is also frequently used to line the interior of crates and boxes: the VCI bubble film is cut to size and placed as a base or wrapper, creating a protective and cushioned environment.
Desiccant bags with VCI
Desiccant bags with VCI combine two key technologies for metal protection: moisture absorption and active corrosion inhibition. They are designed to safeguard metal components during storage or transport under adverse climate conditions — particularly when humidity is a significant risk.
These bags contain desiccant materials designed to absorb and retain excess moisture within enclosed spaces. At the same time, they also incorporate VCI compound that release protective molecules, forming an invisible layer on metal surfaces and effectively blocking oxidation.
This combined action guarantees a dry and protective atmosphere within the packaging, prolonging the service life of metal products without the need for protective oils or additional treatments. The bags are easy to use, maintenance-free and adaptable to a range of logistical formats.
At Inviker we supply desiccant bags with VCI in convenient pouches, ready to be placed directly into sealed packaging, crates, maritime containers or aluminium covers. They are compatible with any packaging solution that can provide an airtight environment.
Industrial applications and recommended sectors
In industry, desiccant bags with VCI are particularly effective in contexts where humidity and prolonged exposure pose a significant risk:
- Sea and air transport, especially for long-distance export journeys.
- Prolonged storage in industrial buildings, non-climate-controlled facilities or outdoor storage.
- Electronics and precision components, which require stable, moisture-free conditions.
- Aerospace, defence and heavy machinery, where high-value equipment must be kept in perfect condition upon delivery.
Best practices for use
To maximize results and guarantee effective protection, we recommend:
- Calculate the appropriate amount of desiccant based on packaging volume and expected exposure time.
- Add the bags just before closing the packaging, avoiding unnecessary exposure to ambient humidity.
- Combine with barrier film or aluminium covers, creating a sealed environment in which both the desiccant and VCI can perform optimally.
This combined solution is a practical innovation for industrial settings where reducing risks and preventing deterioration of critical components during transport and storage is a top priority.

Industrial applications of anticorrosive packaging
Anticorrosive packaging plays a key role in industrial sectors that need to protect high-value metal components from aggressive environmental conditions, repeated handling or long storage periods. The proper application of VCI (volatile corrosion inhibitor) materials, combined with appropriate logistical practices, makes it possible to avoid premature failures, delays and commercial complaints, thereby improving the overall profitability of the supply chain.

Industrial sectors requiring advanced anticorrosive protection
The use of VCI materials is particularly prevalent in sectors where metal components are critical to the functionality of complex products or where logistical and environmental conditions demand a high level of protection.
- Automotive: in production and maintenance, components such as engine blocks, machined parts, bearings, threaded assemblies or calibration tools need protective packaging. VCI packaging allows direct assembly without the need for degreasing afterwards.
- Aerospace and defence: components with tight tolerances and structural responsibilities such as actuators, hydraulic components or lightweight metal structures, require clean, residue-free packaging that will not affect their performance.
- Steel and metallurgy: raw or semi-finished materials (sheets, strips, tubes, steel or aluminium coils) are packed with VCI to protect them from the factory all the way to the end customer, preventing oxidation due to condensation during transport or storage.
- Industrial machinery and equipment: sub-assemblies, spare parts and large metal structures destined for export or extended storage require durable, adaptable protective solutions, especially for components with irregular dimensions or large volumes.
In all these sectors, VCI packaging not only prevents corrosion damage, but also improves operational efficiency and compliance with regulations, simplifying subsequent processes such as assembly, inspection or delivery to the customer.

Use cases: sea transport and long-term storage
Two of the most challenging scenarios for metal components are international sea transport and prolonged storage without climate control.
- During sea transport, materials are exposed to high humidity, saline conditions and temperature fluctuations. The combination of VCI paper or plastic film with aluminium barrier covers and desiccant bags helps to create a dry micro-environment, saturated with inhibitor vapour, ideal for preserving components for weeks or months in transit.
- For long-term storage, risks such as condensation, environmental dirt or residual humidity increase over time. To avoid cumulative corrosion, it is recommended to use closed packaging with VCI emitters, intermediate VCI sheets or bags, and renewal of desiccants if necessary.
Both cases require not only the use of appropriate materials but careful planning to account for the metal’s properties, exposure duration and final destination.
Best practices for proper application of VCI materials
For anticorrosive materials with VCI technology to be effective, it is essential to apply them following best practices. Failures in corrosion protection often result from application errors and not from the material itself.
Here are the key principles to consider in industrial environments:
- Clean and dry components before packaging: traces of dust, oil or moisture can undermine the formation of the protective layer.
- Correct placement of VCI material: for example, the treated side of VCI paper should face the metal, or sufficient spacers should be evenly distributed in higher-volume packaging.
- Controlled environment: the protective atmosphere depends on proper containment. Bags, boxes or covers should be well sealed.
- Avoid incompatible materials: metal components should not come into contact with untreated paper, cardboard, wood or aggressive foams that may absorb or neutralise the effects of VCI.
- Training and internal control: warehouse workers should be trained in proper storage, handling and use of VCI materials, from delivery through to final packaging, to guarantee maximum protective performance.
In our practical guide to applying VCI materials, we go into depth on each of these points, offering useful tips and recommendations for factory workers and logistics managers.
How to choose the right anticorrosive material
Selecting the appropriate anticorrosive packaging is a technical decision that must take into account both the characteristics of the product and additional packaging materials, as well as the logistical and environmental conditions in which it will operate. The right choice protects components, improves operational efficiency, avoids hidden costs and strengthens the reliability of industrial deliveries.
Assess environmental conditions and duration of exposure
The first step is to analyse the environment to which metal components will be exposed:
- Relative humidity, saline conditions or aggressive atmospheres (such as coastal areas, industrial sites with contaminants or sea transport).
- Duration of storage or transit, especially for export or extended periods in non-climate-controlled facilities. A detailed analysis is required, depending on the destination. Shipping components by road to Finland is not the same as delivery to Korea by combined transport. The protective solution must be tailored to these conditions.
- Frequency of handling or inspection, which may require reusable or easily accessible solutions.
The more challenging the conditions, the greater the level of protection the packaging must provide, combining, if necessary, VCI anticorrosive packaging with desiccants or physical barriers.
Consider the type of metal to be protected
Not all metals are equally susceptible to corrosion. It’s therefore crucial to know the composition of the components:
- Carbon steel and cast iron, more prone to oxidation in the presence of humidity.
- Aluminium and light alloys are susceptible to galvanic corrosion and certain atmospheric contaminants.
- Non-ferrous metals such as copper, brass or zinc require compatible inhibitors to avoid adverse reactions.
In this context, Inviker’s VCI solutions are formulated to provide multimetal protection, ensuring effective coverage for different components within a single packaging solution.
Compatibility with other packaging systems
Anticorrosive packaging must integrate seamlessly into existing logistical systems:
- Compatibility with cardboard or wooden crates (ensuring isolation with VCI or neutral materials).
- Adaptability to palletisation, stacking or automated transport formats.
- Ability to combine with barrier film, desiccant bags or control sensors, depending on customer requirements.
In many cases, the most effective solution is a multilayer system designed to protect against multiple risks at once – impacts, humidity, vibrations and oxidation.

Innovation and sustainability in anticorrosive packaging
Innovation in industrial anticorrosive packaging is no longer driven solely by protective performance, but also by a need to meet sustainability goals, safeguard workers’ health and align with regulatory requirements. In a context of global industrial transformation, companies demand materials that perform effectively while reducing their environmental footprint and integrating seamlessly into responsible logistics chains.
New developments in recyclable and monomaterials
One of the main innovations in recent years has been the development of recyclable and monomaterial VCI materials, which simplify waste management and support a circular economy. Whereas multilayer packaging previously made disposal challenging at the end of its service life, today it is possible to use VCI solutions made from:
- 100% recyclable polyethylene, with or without post-industrial or post-consumer recycled content.
- Biodegradable kraft paper with VCI, suitable for standard paper recycling streams.
- Monomaterial structures, particularly useful when combining functions (anticorrosive + cushioning + barrier) without needing to blend incompatible materials.
At Inviker, many products have been optimised to meet sustainability criteria without compromising technical performance. This kind of innovation is especially valued in sectors that prioritize environmental traceability or must conform to internal policy or customer requirements for sustainability across their supply chains.
Nitrite free VCI products compliant with European regulations
The transition to nitrite-free VCI products is another key innovation in this field. Although compounds such as nitrites and amines were frequently used in the past due to their protective properties, it has become clear that they pose health risks to workers and to the environment.
For this reason, at Inviker we focus on developing formulations that are free from hazardous compounds and compliant with recognised European regulations, such as:
- REACH (Registration, Evaluation and Authorisation of Chemicals),
- RoHS (Restriction of Hazardous Substances in Electrical and Electronic Equipment), and
- TRGS 615, a German standard specific to the safety of corrosion inhibitors.
This new generation of VCI products guarantees effective and reliable anticorrosive protection, while meeting the highest quality standards and reflecting a responsible approach to the packaging’s life cycle.
Conclusion: key factors for an effective corrosion protection strategy
Corrosion remains one of the main causes of deterioration, financial losses and logistical complaints in industrial sectors that handle metal components. Against this backdrop, having a well-planned anticorrosive protection strategy is essential for assuring product quality, optimising resources and maintaining competitiveness and profitability in industrial operations.
Anticorrosive packaging solutions with VCI, when applied correctly, help to avoid damage before it occurs, ensuring components arrive in perfect condition at their destination and preventing hidden costs such as reprocessing, delays or returns.
As we have explained in this guide, choosing the right material involves considering numerous factors: metal type, environmental conditions, duration of transport or storage, compatibility with other materials, ease of application and applicable regulations. VCI packaging on its own is not enough to guarantee success. It must be applied properly, stored under suitable conditions and supported by adequately trained teams to maximize its effectiveness.
Anticorrosive packaging should be viewed as an investment with a return. At a relatively low cost, it protects high-value components, safeguards deliveries and reputation, and helps to avoid costly disruptions. Furthermore, the ongoing development of more sustainable, safer and more adaptable materials demonstrates that it is entirely possible to improve protective performance without compromising environmental responsibility or operational efficiency.
In this context, having a specialist’s support makes all the difference. At Inviker we have more than sixty years’ experience helping industrial companies with tailored anticorrosive packaging solutions. Our approach is not just about selling materials, but designing complete protective strategies that respond to each customer’s real-world challenges – from packaging design through to after-sales support.
Investing in proper anticorrosive packaging means protecting the whole value chain.
