(57) [Problem] To provide a heat-shrinkable multilayer film excellent in transparency, heat-shrinkability, rigidity, impact strength and perforation cutability of a virgin material and a film obtained by mixing a return material with a virgin material. To provide. A copolymer having a specific refractive index, comprising a styrene monomer and a (meth) acrylate monomer, A rubber-like elastic resin having a specific refractive index, and at least one layer formed of an A component comprising a styrene monomer and a specific block copolymer of a conjugated diene; and a styrene monomer and a conjugated diene. B component having a specific refractive index mainly composed of a block copolymer, a styrene-based polymer, and a copolymer composed of a styrene-based monomer and a (meth) acrylate and / or (meth) acrylic acid. A heat-shrinkable multilayer film comprising at least one layer formed. |
