The present invention provides a heat-shrinkable laminated film which exhibits excellent breakage resistance, stiffness and shrink finishing quality, and provides a molded product and heat-shrinkable label using the films, and a container. The heat-shrinkable laminated film is made of an A layer mainly constituted of a polyester series resin and a B layer mainly constituted of a polystyrene series resin, respectively used as front and back layers and an intermediate layer, in which a peak temperature of the loss elastic modulus (E A ″) of a resin that constitutes the A layer exists at least one in the range of 50° C. or more and 90° C. or less; the storage elastic moduli (E A ′) at 0° C. and 40° C. satisfy E A ′(0)/E A ′(40)≦1.2, and the storage elastic moduli (E B ′) at 50° C. and 90° C. of the resin that constitutes the B layer satisfy E B ′(50)≧1.5×10 8 Pa and E B ′(90)≧5.0×10 7 Pa; storage elastic modulus curves of E A ′ and E B ′ intersect with each other; and the thermal shrinkage ratio in a main shrinkage direction of the film when the film is dipped in a hot water at 80° C. for 10 sec is 30% or more and 60% or less, and the thermal shrinkage ratio in a direction perpendicular to the main shrinkage direction is −5% or more and +5% or less in the range of 70° C. or more and 80° C. or less. |
