Cortec Corp., St. Paul, Minnesota, has developed EcoShield VpCI-144 paper, a vapor-phase corrosion-inhibiting moisture-barrier paper that can be fully repulped.
According to a news release from Cortec, the recyclable corrosion-inhibiting paper provides a competitive, environmentally friendly alternative to polyethylene (PE) and wax paper, with comparable water vapor barrier properties. The paper is fully repulpable per the Fibre Box Association Voluntary Standard. It also can be recycled into many types of paper products, such as boxes, cardboard and other corrugated materials.
EcoShield VpCI-144 paper does not contain nitrites, phosphates, silicones, chromates and other heavy metals. The paper protects against corrosion for both ferrous and nonferrous metals, eliminating the need to stock several products for different metal types. The EcoShield VpCI-144 papers:
• provide protective wrap for individual components;
• offer end closures for shipping tubes;
• serve as an insert strip for recessed areas in large packages; and
• can be sheet liners or separators between products.
EcoShield VpCI-144 paper offers corrosion protection and moisture resistance in the bearings industry. Manufacturers can use it to package new bearings for shipment, and the bearings can be wrapped and protected until they are needed for assembly. Other applications include protection of metal coils, wire reels, plates and bars.
Metal parts wrapped in EcoShield VpCI-144 paper are protected against rust by an invisible molecular corrosion-inhibiting layer that forms on the surface of metals as VpCI molecules in the paper vaporize, fill the enclosed space and are attracted to the metal. Cleaning of the VpCI layer is not required because the protective layer will float away once the part is removed from the package, allowing immediate use.
