Alongside the desiccant range we supply vapour corrosion inhibitor film and moisture barrier packaging for metal and engineering goods — the complementary half of corrosion protection, working on the metal surface rather than on the air around it.
Specifications, grades and sizes for this range are confirmed on enquiry. Tell us the part, the packing method and the storage period and we will quote against it.
Vapour phase inhibitor that forms a protective molecular layer on the metal itself.
Foil laminate barrier that makes a desiccant charge meaningful in the first place.
ISPM-15, IATA and ISO compliant packing for global shipments.
Odd sizes, alternative pouch materials and printed packs to your artwork.
