ABSTRACT:
A protective coating and a metal protected by the coating is provided as well as laminates and thermoplastic films useful for making the protected metal surfaces. The coating comprises a multilayer or dual-film coating. The first film is an adhesive layer to hold the second film as a protective coating to the metal surface. The first film may be either a monolayer or dual-layer film of ethylene acrylic acid and carboxy-modified polyethylene. The second film is extruded over the first and comprises a low density polyethylene. The protective coating provides increased abrasion resistance and superior adhesion as demonstrated by peel strengths between both the film to extrudate interface and the film to metal interface.
