摘要： The present disclosure relates to a multilayer film having, in this order: a first outer layer serving as a heat-seal layer and containing a propylene homopolymer (A), a propylene-ethylene random copolymer (B), and an anti-blocking agent (C); an inner layer containing a propylene-ethylene block copolymer (D) and an ethylene-propylene copolymer elastomer (E); and a second outer layer containing the propylene homopolymer (A) and the propylene-ethylene random copolymer (B). The content of the component (C) is 0.5 to 3.0 parts by mass relative to 100 parts by mass of the components (A) and (B) together, and the component (C) includes, relative to a total mass of the component (C), 45 to 75% by mass of particles (C1) with an average particle diameter of 1.0 to 4.0 µm and 55 to 25% by mass of particles (C2) with an average particle diameter greater than 4.0 µm and equal to or smaller than 7.0 µm.

摘要： A multilayer film including a first outer layer containing 70 to 30% by mass of a propylene homopolymer (A) and 30 to 70% by mass of a propylene/ethylene random copolymer (B) having an ethylene content of 5% by mass or less, an inner layer containing a propylene/ethylene block copolymer (C) and an ethylene/propylene copolymer elastomer (D), and a second outer layer containing 70 to 30% by mass of the propylene homopolymer (A) and 30 to 70% by mass of the propylene/ethylene random copolymer (B) having an ethylene content of 5% by mass or less, in that order.
