Metal parts rust while they wait in storage and while they travel. The classic answer is to oil the part before packing. It works, but it has a price: the oil must be removed before assembly. That means extra labour, extra chemicals, extra time and extra waste.
What VCI does
VCI stands for Volatile Corrosion Inhibitor. The compound is blended into the film. Once the pack is closed it evaporates slowly and fills the air inside. When it reaches the metal surface it forms a protective layer there — invisible, molecular in thickness.
That layer keeps moisture and oxygen away from the metal, disabling both of the things corrosion needs to start. When the pack is opened the compound disperses and the part can be used straight away — there is no degreasing step.
Which metals it suits
- Steel and cast iron
- Iron
- Copper and brass
- Aluminium
- Chrome-plated parts
The raw material we use is from the German brand BRANOpac. The product can be made as bags, rolls, films and papers, cut to the part's dimensions and printed if required.
Where it earns its keep
It is used most in automotive supply, machine building and spare-part shipping. The difference is clearest on consignments that travel by sea and sit for weeks in high humidity.
Choosing the right product
Send us the material and dimensions of the part, how many months of protection are needed, and the environment the pack will sit in. Protection depends on the pack staying closed: if it is opened and closed repeatedly the compound disperses and protection is shortened — a point worth factoring into the choice.
