[Project] To provide a block copolymer resin composition, a heat-shrinkable multilayer film, and a heat-shrinkable label, which has excellent adhesive performance with a polyester-based resin. [Solutions] 85 to 99.5 parts by mass of the resin component A and 0.5 to 15 parts by mass of the resin component B, the resin component A contains at least one vinyl aromatic hydrocarbon-conjugated diene block copolymer, and a vinyl aromatic hydrocarbon and the mass ratio of the conjugated diene is 80/20 to 65/35, the resin component B has a mass ratio of the vinyl aromatic hydrocarbon to the conjugated diene of 30/70 to 0/100, and the number average molecular weight is 5,000 to 40,000 vinyl aromatic hydrocarbon-conjugated A block copolymer resin composition which is a diene block copolymer or a conjugated diene polymer. |
