Title:
STRETCH FILM FOR PACKAGING
Document Type and Number:
Japanese Patent JP3812192
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a stretch film for packaging having processing stability, transparency, flexibility, cutting properties and high strength and excellent in heat fusion resistance and deformation restoring properties.
SOLUTION: In a stretch film constituted of at least three layers, both surface layers are constituted of an ethylenic polymer characterized by that fusion calorie is 80-120 J/g and the fusion calorie ratio of 70°C or lower to the total fusion calorie is 0-40% and melt tension at 180°C is 1-10 g and at least one intermediate layer is constituted of a resin compsn. containing a propylene polymer of which the fusion calorie is 20 - below 80 J/g.
