Metal deposited polypropylene film

Abstract

Abstract PURPOSE:To enhance metal bonding strength, and to improve printability, laminated layer bondability with other film or the like, and processability by depositing metal on a film which employs a composition to which specific amount of specific silicone resin powder to polypropylene resin. CONSTITUTION:Metal is deposited on a film which has a composition in which 0.01-1.0pt.wt. of nonmeltable spherical silicone resin powder is added to 100pts. wt. of polypropylene resin. The polypropylene resin contains 85pts.wt. or more of propylene component, and is of crystalline ethylene-propylene copolymer or crystalline propylene-butene-1 copolymer or crystalline ethylene-propylene- butene-1 tertiary copolymer of 120-150 deg.C of crystal melting point. The silicone resin is of a regular spherical polyalkylsiloxane having 5mum or less of mean particle size, 0.5 or less of bulky specific weight and 300 deg.C or higher of decomposing temperature. The metal used for the deposition is aluminum.
