PROBLEM TO BE SOLVED: To obtain a film which is environmentally friendly and possesses excellent flexibility, mechanical strength, elastic recovery and other properties by mixing a polyolefin resin with a specific amt. of a styrenic thermoplastic elastomer and forming the obtd. mixture into film. SOLUTION: A polyolefin resin (e.g. polypropylene) in an amt. of 100 pts.wt. is mixed with 5 to 1000 pts.wt. styrenic thermoplastic elastomer (e.g. a styrene/ ethylene/butylene/styrene elastomer). the obtd. mixture is molded by extrusion, calendering, non-stretched film molding, stretched film molding or the like to obtain a film 1. This film 1 is free from drawbacks inherent in vinyl chloride films, such as blushing and migration of a plasticizer, and can be used as an alternative for the vinyl chloride film. The formation of a pattern layer on the film 1 through a release layer optionally followed by formation of an adhesive layer thereon can provide a sheet for boil decoration processing excellent design effect, hand and other properties. |
