Title:
OLEFIN RESIN MULTILAYER FILM OR SHEET
Document Type and Number:
Japanese Patent JP3215817
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve damage resistance, heat resistance and cuttability by forming a soft multilayer film or sheet used for a stationery, various cases and the like, packaging, agriculture or the like of an intermediate layer made of a specific ethylene resin, and an outer layer made of a specific propylene resin.
SOLUTION: An olefin resin multilayer film or sheet 1 is formed of an intermediate layer 11 made of an ethylene resin and outer layers 12 (12a, 12b) made of a propylene resin formed on both surfaces of the layer 11. In this case, an ethylene resin containing one type selected from an ethylene-(meth)acrylic ester copolymer resin and ethylene-vinyl acetate copolymer resin as a main body is used for the ethylene resin for forming the layer 11. As the propylene resin for forming the layer 12, a propylene resin consisting mainly of a mixed resin of a syndiotactic polypropylene and a propylene-ethylene-butene copolymer is used.
