Abstract
PURPOSE: A film with easy openability suitable for the heat sealing of a resin container, which comprises a thermoplastic block copolymer resin or elastomer consisting of a conjugated diene compd. and a vinyl arom. compd., a specified rubber-modified polymer and a propylene copolymer.
CONSTITUTION: The titled film comprising a thermoplastic block copolymer resin (A) of content of a conjugated diene compd. such as butadiene ≤35wt.% (hereinafter abbreviated as %) consisting of a vinyl arom. compd. such as styrene and a conjugated diene compd. or a thermoplastic block copolymer elastomer of conjugated diene compd. content 45W80% consisting of a vinyl arom. compd. and a conjugated diene compd., a rubber-modified polymer (B) obtd. by mixing and polymerizing a vinyl arom. compd. with an elastomer and 10W50% propylene polymer (C) such as atactic polypropylene. It is possible to seal a resin container without use of any adhesive, and the film or container is not damaged during opening because of easy openability.
