EASILY OPENABLE HEAT-SEALING RESIN COMPOSITION

摘要

PURPOSE:To improve heat resistance, peeling strength and interfacial peelability by incorporating a specified ethylene-alpha-olefin copolymer, a propylene-ethylene copolymer and a low-density PE. CONSTITUTION:40-90wt.% ethylene-alpha-olefin copolymer with a density of 0.920 or higher (e.g. ethylene-butene-1 copolymer), 5-40wt.% propylene-ethylene copolymer with an ethylene content of 4-15wt.% and 5-40wt.% low-density PE with a density of 0.930 or lower are melt-kneaded and made into a film of a thickness of 2-100mum. The film is then laminated with a base material.
