Document Type and Number:
Japanese Patent JP3905353
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a low temperature heat-shrinkable multilayered film having surface layers comprising a polypropylene resin and a petroleum resin and/or a terpene resin and an intermediate layer comprising a polyethylene resin and not damaging transparency and glossiness even after heat shrinkage.
SOLUTION: Both surface layers comprise a resin composition prepared by mixing 50-150 pts.wt. of the petroleum resin and/or the terpene resin and 50-800 pts.wt. of a polyolefinic thermoplastic elastomer with 100 pts.wt. of the polypropylene resin and the intermediate layer comprises the polyethylene resin.
