Abstract: A heat-shrinkable film which is excellent in mechanical characteristics such as heat shrinkage characteristics, impact resistance, and transparency and in the finish of shrinkage and which is suitable for shrink packaging, shrink bundling, shrinkable labels, and so on. A film which is made from a mixed resin comprising as the main components either a polylactic acid resin (A) and a (meth)acrylic resin (B) or a polylactic acid resin (A) and a silicone/acrylic composite rubber (D) or has at least one layer made from the mixed resin and which exhibits a heat shrinkage percentage of 20% or above in the main shrinkage direction when dipped in water at 80° C. for 10 seconds.

Abstract: The present invention provides a heat-shrinkable laminated film including at least two layers, in which the first layer is composed of at least one kind of a polylactic acid series resin as the main component and the second layer is composed of at least one kind of a polyolefin series resin as the main component. Heat shrinkage ratio of this film in the film main shrinking direction is 30% or more when dipped in warm water of 80° C. for 10 seconds. Since this heat-shrinkable laminated film is made from a plant-derived resin, it promotes a use of biomass. Also, as this film exhibits excellent shrinkage property in low temperature, film rigidity, shrink finishing quality, and small natural shrinkage ratio, the film is suitably used for a molded product which requires heat shrinkage property, specifically, it is suitably used for shrinkable label.

Abstract: 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 (EA?) 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 (EA?) at 0° C. and 40° C. satisfy EA?(0)/EA?(40)?1.2, and the storage elastic moduli (EB?) at 50° C. and 90° C. of the resin that constitutes the B layer satisfy EB?(50)?1.5×108 Pa and EB?(90)?5.

Abstract: The present invention provides a heat-shrinkable laminated film, which exhibits excellent film rigidity, shrink finishing quality, transparency of the recycled film, and a small natural shrinkage, with suppressed film interlayer peeling and shrinking stress, and which is applicable to shrinkable packing, shrinkable bond-packing, shrinkable label and the like. The heat-shrinkable laminated film comprises: a surface layer (S layer) composed of a polyester series resin composition containing a polyvalent carboxylic acid residue and a polyvalent alcohol residue; a middle layer (M layer) composed of a styrene series resin composition; and an adhesive layer (AD layer) which contains a copolymer of styrene series hydrocarbon and a conjugated dienic hydrocarbon or hydrogenated derivatives thereof, and having a styrene series hydrocarbon content rate to the entire copolymer or hydrogenated derivatives is 5˜40 mass % or less.
