| abstract |
An object of the present invention is to provide a heat-shrinkable film excellent in mechanical properties such as heat-shrinkage properties, impact resistance and transparency, and shrinkage finish, and suitable for applications such as shrink-wrapping, shrink-bound packaging, and shrink-labels. A polylactic acid resin and a silicone acrylic composite rubber are contained as main components in a predetermined content ratio, and the polylactic acid resin is a copolymer of D-lactic acid and L-lactic acid, or a copolymer thereof. The D / L ratio of D-lactic acid and L-lactic acid is 3/97 to 15/85, or 85/15 to 97/3, is stretched in at least one direction, and is heated at 80 ° C. The thermal shrinkage rate in the main shrinkage direction when immersed for 10 seconds is set to 20% or more. [Selection figure] None |
