Abstract

PURPOSE:To improve heat resistance and shrink characteristics by composing the composition of a heat-shrinkable film of an ethylene-propylene block copolymer and an ethylene-propylene random copolymer having a specific copolymer ratio in the heat-shrinkable film consisting of a foam layer having an expansion ratio of decuple or less and a solid propylene polymer layer. CONSTITUTION:A 50-90wt.% ethylene-propylene block copolymer having the copolymerization ratio of ethylene of 3.0-20wt.% and a 50-10wt.% ethylene- propylene random copolymer having the copolymerization ratio of ethylene of 2.0-15wt.% are compounded. Said compound and a chemical foaming agent are mixed uniformly, thus acquiring a composition. A propylene polymer is co-extrusion-molded onto both surfaces and one surface of a foam layer having said composition and the foam layer and the raw fabric of a laminated film is formed, and drawn, thus obtaining a heat-shrinkable film. The expansion ratio of said foam layer is set to decuple or less at that time. Accordingly, the heat-shrinkable film excellent in heat resistance and shrink characteristics can be acquired.
