VpCI® multimetal paper offers both traditional protective packaging and corrosion protection for carbon steel, galvanized Steel,  stainless steel, cast iron, aluminum alloys, copper, and brass​. VpCI® paper packaging allows for the seamless integration of corrosion protection into your packaging process. VpCI's migrate from the paper to the metal VpCI creating a chemically adsorbed molecular layer that provides multimetal corrosion protection. The coverage is complete – all surfaces, crevices, cavities, and other inaccessible void areas receive protection. The VpCI® barrier is self-replenishing, even for packaging that’s repeatedly opened, and typically protects for up to 24 months.
