PROBLEM TO BE SOLVED: To provide a heat-shrinkable multilayer film having superior low-temperature shrinkability, stiffness, low-temperature elongation, transparency and peel strength.SOLUTION: A heat-shrinkable multilayer film includes surface layers and an intermediate layer and is stretched uniaxially at the least. The surface layer contains at least one kind of polyester resin and the intermediate layer contains: 1-60 mass% of a block copolymer mixture of a block copolymer (A) comprising a vinyl aromatic hydrocarbon and conjugated diene with a block copolymer (B) comprising the vinyl aromatic hydrocarbon and conjugated diene; and 40-99 mass% of a block copolymer (C) comprising the vinyl aromatic hydrocarbon and conjugated diene. |
