Abstract
(EN)
In a heat-shrinkable multilayer film pertaining to the present invention, an inner surface layer that is in contact with contents, an adhesive layer, and an intermediate layer that is adjacent to the adhesive layer are layered in the stated order from inside to outside. The inner surface layer includes an ethylene-vinyl acetate copolymer, the adhesive layer includes an acid-modified ethylene copolymer, and the intermediate layer includes a polyamide-based resin.
