PROBLEM TO BE SOLVED: To provide shrinkage packaging, shrinkage-bound packaging, shrinkage labels, etc. that have excellent film stiffness (rigidity at room temperature), shrink finish, transparency at the time of regeneration addition, excellent natural shrinkage, and suppressed delamination of the film A heat-shrinkable laminated film suitable for use, and a plastic container equipped with a heat-shrinkable label made of the film. A surface layer (S layer) composed of a polyester-based resin composition containing at least one polyester resin containing a polyvalent carboxylic acid component and a polyhydric alcohol component as a main component, and a styrene-based resin composition. Intermediate layer (M layer), a copolymer of a vinyl aromatic hydrocarbon and a conjugated diene hydrocarbon or a hydrogenated derivative thereof, and a styrene content in the copolymer or hydrogenated derivative is 5% by mass In a laminated film having an adhesive layer (AD layer) composed of a resin composition that is 40% by mass or less, the tensile elastic modulus in the direction orthogonal to the main shrinkage direction of the film is 1200 MPa or more and immersed in 80 ° C. warm water for 10 seconds. The thermal shrinkage rate when stacked is 30% or more in at least one direction. [Selection figure] None |
