PROBLEM TO BE SOLVED: To provide a heat-shrinkable laminated film, a heat-shrinkable label, which has excellent film stiffness (rigidity at room temperature), shrinkage finish, transparency at the time of regeneration addition, small natural shrinkage, and sufficient delamination delamination A container with the label is provided. SOLUTION: (I) layer mainly composed of polyester resin, copolymer of styrene hydrocarbon and conjugated diene hydrocarbon, and mass ratio of styrene copolymer of 40/60 to 90/10 Between at least three layers having a (II) layer mainly composed of a copolymer of a styrene hydrocarbon and a conjugated diene hydrocarbon or a hydrogenated derivative thereof between the (III) layer mainly composed of a mixture The film has a thermal shrinkage rate of 40% or more in at least one direction when immersed in warm water at 80 ° C. for 10 seconds, and spontaneous shrinkage when stored in an atmosphere of 30 ° C. and 50% RH for 30 days. A heat-shrinkable laminated film having a rate of less than 3%. [Selection figure] None |
