VCI combats corrosion by preventing acids and high humidity from accelerating energy loss in metallic substances.This is achieved by both contact and volatile inhibitors, which form a thin protective layer on the surface of the metal.This molecular layer is self replenishing to give long term protection, but does not need to be wiped away before the metal item is put to its intended use.The volatile nature of the inhibitors allows all surfaces of irregular shaped items to be protected.

Corrosion Inhibitor Films:
Thickness from 25 micron to 200micron In-built VCI' s for all metals.
Wide variety of translucent colours available, all allowing visual inspection of the items protected without opening the pack.
Heat shrinkable, stretch, high slip and standard polythene constructions available.
Special constructions available in modest quantities.
Unrivalled combination of polythene barrier properties and corrosion protection.
Heat sealable and suitable for use in the automated polythene packaging equipment.
Available in all forms and sizes of bags, tubing and sheeting.
Compatible use with corrosion inhibitor papers
Ideal for component bags, carton or case liners, pallet covers, interleaves, sleeves, all tailored to customer specific requirements.

Usage recommendations:
Providing the metals are clean, dry and free from corrosion when packed in VCI film, long term protection can be expected over a number of years if our usage recommendations are followed.A network of stockists and distributors are available to assess the protection requirements of a wide range of metals and materials and can be tailored to suit customers preferred packaging methods.All film and paper products can be printed on one side and are available with VCI action on one or both sides.They can also be recycled or removed with other waste materials of the same type I.E.Packaging paper or film.
