    摘要: A heat shrinkable multilayer film comprising an outer surface layer (a) formed of a thermoplastic resin, a first intermediate layer (b1) formed of a polyamide resin, a second intermediate layer (b2) formed of a saponified product of an ethylene-vinyl acetate copolymer, and an inner surface layer (c) formed of a polyolefin resin, wherein the shrink of the heat shrinkable multilayer film in water at 90° C. is within a range of from 3 to 45% in each of machine and transverse directions, and the polyamide resin is a mixture of 60 to 90% by weight of an aliphatic polyamide having a melting point of 210° C. or higher and 10 to 40% by weight of an aromatic polyamide comprising isophthalic acid and terephthalic acid as main components.
