Cortec has been awarded a patent for its newest film technology, EcoShield VpCI-226, a nitrite-free film that protects metals from corrosion. It follows a significant number of other patents that Cortec has received over the years related to vapor corrosion inhibitor (VCI) film technology, including VCI films with recycled content and fire-retardant and biodegradable VCI films.

Metal parts, including molds and mold components, packaged in Ecoshield VpCI-226 receive continuous protection against salt, humidity, condensation, moisture, aggressive industrial atmospheres, and dissimilar metal corrosion. Vapor phase corrosion inhibitors in the film vaporize and condense on metal surfaces in the enclosed package, protecting exterior as well as hard-to-reach interior surfaces. EcoShield VpCI-226 provides complete product protection during storage as well as during domestic and overseas shipments, virtually eliminating rust claims. It protects multiple types of metal, including aluminum, galvanized steel, carbon steel, stainless steel, copper, and brass.

EcoShield VpCI-226 film and bags are available in different sizes and constructions, from small, top-seal bags that protect nuts and bolts to 30-foot-wide sheeting for storing large industrial equipment. They are non-hazardous and recyclable, and can be manufactured using an array of the most advanced resins. Custom blends are available to provide the exact properties needed, such as puncture resistance or tear strength. EcoShield VpCI-226 film and bags replace conventional rust preventatives such as oil and desiccants, saving time and hassle by eliminating degreasing and coating removal, said Cortec.
