A plastics film suitable for coating with another material consists of a blend of polypropylene and an acid terpolymer. The acid terpolymer is preferably a copolymer of an ester monomer, such as methyl acrylate, an alkyl methacrylate or an alkyl hydrogen maleate; an acidic monomer, such as acrylic acid, methacrylic acid or maleic acid; and ethylene. n This plastics film may be coated with a thin layer of metal to form a composite film. |
