PROBLEM TO BE SOLVED: To provide a polyolefin multilayer film for food packaging having excellent transparency and shrinkage characteristics. SOLUTION: The multilayer film comprises at least one surface layer (X) and a core layer (Y). The surface layer (X) is composed of a resin composition comprising 50-99 wt% of a polypropylene resin (A) having a melting point of 120-170°C, and 1-50 wt% of propyleneα-olefin copolymer (B) having a melting point lower than 120°C and containing 5-50 mol% ofα-olefin. The core layer (Y) is composed of an ethylene (co)polymer. COPYRIGHT: (C)2006,JPO&NCIPI
