Cor-Pak® EX VpCI® Film

Product Description

Cor-Pak EX VpCI Film is made using high-density polyethylene and extruding with Vapor phase Corrosion Inhibitors (VpCI) to protect ferrous and most non-ferrous metals from corrosion. 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.
