    • 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 x 10 8 Pa and E B ' (90) ‰§ 5.0 x 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.
    • 本发明提供具有优异的耐破损性,刚性和收缩整理质量,并提供使用该膜的成型产品和热收缩标签以及容器的热收缩性层压膜。 热收缩层压膜由主要由聚酯类树脂构成的A层和主要由聚苯乙烯类树脂构成的B层构成,所述B层分别用作前后层和中间层,其中, 构成A层的树脂的损耗弹性模量(EA“)在50℃以上且90℃以下的范围内存在至少一个; 在0℃和40℃下的储能弹性模量(E A')满足E A'(0)/ E A'(40)‰& 1.2,并且构成B层的树脂在50℃和90℃下的储能弹性模量(E B')满足E B'(50)‰& 1.5×10 8 Pa和E B'(90)‰§ 5.0×10 7 Pa; E A'和E B'的储存弹性模量曲线相互交叉; 当将膜浸渍在80℃的热水中10秒时,膜的主收缩方向上的热收缩率为30%以上且60%以下,并且垂直于 主收缩方向在70℃以上且80℃以下的范围内为-5%以上且+ 5%以下。
