Cor-Pak® EX VpCI Film is made using high-density polyethylene and extruded with Vapor phase Corrosion Inhibitors (VpCI). Simply wrap the metal object with Cor-Pak® EX film. The VpCI in the film volatilizes and migrates with air then condenses on all metal surfaces, reaching all exposed and recessed areas. Cor-Pak® EX VpCI Film provides a high level of corrosion inhibitor protection along with the excellent moisture barrier properties of high-density polyethylene film. It is unaffected by most solvents, strong acids and alkalies. Incorporating Cortec’s proven Vapor phase Corrosion Inhibitors, Cor-Pak® EX VpCI Film is the ideal solution when a combination of multimetal and mechanical protection is desired.
