HEAT-SHRINKABLE LAMINATED POLYLACTIC ACID FILM, MOLDING USING THE FILM, HEAT-SHRINKABLE LABEL, AND CONTAINER WHICH USES THE MOLDING OR TO WHICH THE LABEL IS ATTACHED

摘要

PPROBLEM TO BE SOLVED: To provide a heat-shrinkable laminated film which makes the break resistance of the film be satisfied, is excellent in transparency and low-temperature contraction characteristics, and is suitable for applications including contraction package, contraction binding package, and a contraction label. PSOLUTION: The laminated film has at least two layers of a layer (A) made of a resin composition containing a polylactic acid resin as the main component and an ethylene-vinyl acetate resin and a layer (B) made of a resin composition containing a polylactic acid resin, a polyolefin resin, and a compatibilizer improving the compatibility between the polyolefin resin and the polylactic acid resin. The thermal shrinkage rate in the main contraction direction of the laminated film when the film is stretched in at least one direction and immersed in hot water of 80C for 10 sec. is at least 20%.
