Detailed Product Description
MPPL VCI is a transparent, bluish special polyet hylene film; it is nitrite- and amine-free and features active VCI corrosion protection on both sides. It is waterproof, weldable and suitable for use in automated packaging processes and for bag manufacturing.
The film continually releases small amounts of active substances into the atmosphere inside the packaging, meaning that metal surfaces that are not directly in contact with the film also benefit from protection. The distance between film and the surrounding metal surfaces will depend on the packaging volume and the amount of time needed for a protective atmosphere to build up - 10 cm can be used as a rule of thumb. Depending on the packaging volume, it can take up to 20 hours for a sufficient protective atmosphere to dev
Scope of protection
Steel, cast iron (limited, only on contact); reliable corrosion protection for galvanized steel, nickel, aluminium, chrome, zinc, and copper and its alloys. We recommend a compatibility test for cadmium and magnesium alloys.
