<P>PROBLEM TO BE SOLVED: To provide a heat-shrinkable film containing a raw material derived from a plant as a principal component, excellent in transparency, rapture resistance, a low-temperature shrinkage characteristic (shrinkage finish) and bending whitening-resistance, and suitable for application of shrink package, shrink bundling packaging, a shrink label and the like. <P>SOLUTION: This heat-shrinkable laminated film includes a (I) layer comprising a resin composition containing a polylactic resin as the principal component, and containing core shell type rubber, and a (II) layer containing the polylactic resin as the principal component, and containing an ethylene-vinyl acetate resin, wherein a vinyl acetate content is 55-85 mass% in the ethylene-vinyl acetate resin contained in the resin composition constituting the (II) layer, the laminated film is stretched along at least one direction, a rate of heat shrinkage along a main shrinkage direction is 20% or more when immersed into hot water of 80°C for 10 seconds, and an overall haze value of the film having 40 μm of thickness is 9.5% or less when measured based on JIS K7105. <P>COPYRIGHT: (C)2012,JPO&INPIT |
