Japanese Patent JP3953713

B2

PROBLEM TO BE SOLVED: To provide a well-balanced laminated stretch film for packaging food, excellent in packaging properties such as practical heal sealability, finish properties or the like while putting characteristics possessed by a film comprising a cyclic olefinic copolymer to practical use.
SOLUTION: The stretch film for packaging food has at least a mixed resin layer based on three components of 20-50 wt.% of (A) a polypropylene resin, 20-60 wt.% of (B) the cyclic olefinic copolymer having a repeating unit originating from an α-olefin and a repeating unit originating from a cyclic olefin and having a glass transition temperature (Tg) of 30°C or lower and 5-30 wt.% of (C) a copolymer of a vinyl aromatic compound and conjugated diene or a hydrogenated derivative thereof.
