Flange protection film

It is fabric and fibre free, heat sealable or tape sealable film useful for saving Flange from corrosion. It limits passage through itself of solids, liquids, semisolids, gases or forms of energy such as ultraviolet light, said structure compromising a first ply of a relatively tough, biaxially oriented film of organic polymer adhered to a second ploy of metallic foil/coating and a third ply of a tough polymer such as polyethene.
