Overlay films

Abstract

The overlay film of the invention is obtained by forming a substrate layer composed of a resin composition comprising an ethylene copolymer such as ethylene-methacrylic acid ester copolymer and the like and a crystalline polyolefin having a melting point of 110.degree. C. or higher on at least one side of the base layer composed of a crystalline polyolefin and the like by any method such as co-extrusion-laminating and the like followed by cooling. The overlay film is excellent in physical properties such as the anti-blocking property and the like and gives a metal-deposited film with brilliant appearance exhibiting high adhesive strength to the metal layer by vapor-deposition treatment. The metal-deposited film is serviceable for extensive uses including wrapping materials.
