ABSTRACT - 604224 The disclosure relates to a multilayer film comprising an upper layer (A), one or more middle layers (B), and a lower layer (C), laminated in that order. The multilayer film is characterized in that: the middle layer (B) comprises the composition (b1) mentioned below, or a composition (b2)； the upper layer (A) and the lower layer (C) each independently contain an ethylene polymer and/or a propylene polymer. Composition (b1) is a composition comprising: a propylene polymer (p1) having a melting point of 140 to 165 DEG C according to differential scanning calorimetry, and a melt flow rate (MFR； ASTM D 1238, 230 DEG C, 2.16 kg load) of 0.1 to 20 g/10 minutes； a random copolymer of propylene and a-olefin (r1) having a molecular weight distribution of 1.0 to 3.5, as measured by gel permeation chromatography (GPC), and a melting point of 90 to 125 DEG C, as measured by differential scanning calorimetry； and 30 wt% to 60 wt% ethylene-based elastomer (however, the sum of the blending quantities of the propylene polymer (p1), the random copolymer of propylene and a-olefin (r1), and the ethylene-based elastomer is 100 wt%). (If the middle layer (B) is the composition (b1), the ratio of the blending quantity of the propylene polymer (p1) in the whole multilayer film to the sum of the blending quantities of the propylene polymer (p1) and the random copolymer of propylene and a-olefin (r1) in the whole multilayer film is 0.1 to 0.35.)
