摘要： To provide a multi-layered film as transparent as that produced by T-die or water-cooled inflation molding, even when produced by air-cooled inflation molding, and excellent in tearing strength, impact strength, heat-sealing capacity at low temperature and interlayer strength. The multi-layered film comprises a propylene-based resin layer composed of a propylene/α-olefin random copolymer as the major component, which has a melt flow rate (MFR, determined at 230° C.) of 1 to 30 g/10 minutes, melting peak temperature (Tm) of 110 to 165° C. and Mw/Mn ratio of 1.5 to 3.5, and is produced in the presence of a metallocene catalyst, wherein the propylene-based resin layer is laminated, on each side, with a copolymer of ethylene and α-olefin of 3 to 12 carbon atoms, having an MFR (determined at 190° C.) of 0.1 to 20 g/10 minutes and density: 0.860 to 0.925 g/cm3.
