Corrosion protection

Packaging solutions
for metal parts

Although oxygen and water are vital for humans, metal parts must be protected from them. This is because a chemical reaction, corrosion, occurs between a metal, oxygen and moisture from the environment, and the material deteriorates. The best-known example of corrosion is rust. This occurs when iron or steel oxidize in combination with these other elements.

How quickly a metal component rusts depends on various influences, such as temperature, humidity or the amount of pollutants. But one thing is certain: corrosion is permanent and can lead to damage after just a few hours. That is why it is important that metal parts are protected throughout the production process, storage and transport.

And this is where we can help. With customized plastic corrosion protection packaging, we can ensure that any components susceptible to rust reach their destination without any loss of quality or function. We implement corrosion protection in our packaging solutions using three methods: desiccants, VCI and INTERCEPT^®.

Desiccant
Moisture absorption
prevents corrosion

Universal use

Easy disposal

Bags with desiccants, such as silica gel, are used when exporting components abroad, among other things. For this, the goods to be transported are sealed with the required amount of desiccant in an airtight and water-vapor-proof film and packed in an outer packaging, such as a transport container. The barrier film prevents the penetration of moisture, while the desiccant absorbs the humidity inside the packaging. However, this type of corrosion protection only works as long as the packaging is tightly sealed. If the film is opened or damaged, it is no longer effective and corrosionor rust may occur.

Universal use: protects both metallic and non-metallic parts
Goods are instantly ready for use after removing the packaging material
Chemically harmless and easy to dispose of with residual waste

We use desiccant bags in particular, in combination with other corrosion protection products, for example to ensure rapid absorption of the initial moisture in a packaging solution.

VCI
Protection against corrosion through inhibitors

Highly effective

Easy replacement

No residues

VCI are volatile corrosion inhibitors that are introduced into a carrier material and outgas over time. Inside a closed package, this process leads to a protective atmosphere. The active ingredients form a moisture-repellent layer over the surface of the metal parts so that no reaction between metal and moisture can take place. Due to a sustained release of the active ingredients, the corrosion protection builds up again even after the packaging has been opened and resealed. Corrosion protection packaging with VCI is therefore suitable for multiple use and long-term storage.

We integrate VCI dispensers into our packaging solutions because of their special properties. These are placed in capsule or pad form at set positions in the packaging. The solutions implemented include, for example, load carriers for cylinder heads or workpiece carriers for rotor and stator laminations. The benefits: the dispensers have a depot effect and release the active ingredients over a longer period of time. Depending on the amount of VCI, the climatic conditions and outer packaging, the effect can last between a few months and several years – making it ideal for reuse cycles between supplier and manufacturer.

Highly effective and easy to handle
Packaging does not have to be airtight and can be opened
Dispensers can be easily replaced
Active ingredients dissolve completely

INTERCEPT^®
High-tech corrosion protection for metals and other materials

Protection in the material

Long-lasting

Recyclable

Intercept^® is a state-of-the-art corrosion protection for metal parts as well as optical components and plastic products. The material consists of highly porous copper particles that are chemically cross-linked in a plastic matrix. The particles react with corrosive gases in the air and bind them permanently. This creates a neutralizing atmosphere inside packaging, protecting all the goods stored in it. Any moisture that penetrates the packaging is freed from its corrosive components and cannot lead to corrosion. Compared to other corrosion protection solutions, Intercept^®’s effectis even longer-lasting (up to 15 years) and works even under extreme climatic conditions. This makes the material particularly suitable for returnable packaging and export packaging.

By laminating a thin layer of Intercept^® onto the plastic sheets from which our packaging is made, we are able to provide almost any packaging solution with effective corrosion protection. Among other things, engine blocks and steering components have been packed in large load carriers and measuring instruments have been packed in workpiece carriers with this technique. A big advantage here is that no additional packaging materials are needed. There is also no need to regularly replace and dispose of bags or dispensers. In addition, the reusable load carriers remain washable – without losing their protection.

Corrosion protectionincluded in the (plastic) packaging material from the outset
Effective even under extreme temperatures (from -35°C to +80°C)
Free from outgassing chemicals (nitrite, phenols, etc.)
Environmentally friendly, recyclable and easy to dispose of

Benefits for you with corrosion protection packaging

Metal parts in particular, but also components made of other materials, should be protected from corrosion during manufacture, storage and transport. This is best achieved with special corrosion protection packaging, which prevents the material from reacting with moisture and oxygen. The goods no longer have to be laboriously smeared with protective oil or wax and then recleaned. To ensure effective corrosion protection for our packaging solutions, such as transport containers and load carriers, we use two modern solutions: VCI and Intercept^®. Both the VCI active ingredients and the copper particles in the Intercept^® material are long-lasting and are therefore ideal for a reusable container or packaging cycle.
