HEAT-SHRINKABLE FILM, MOLDED PRODUCT AND HEAT-SHRINKABLE LABEL EMPLOYING THE FILM, AND CONTAINER EMPLOYING THE MOLDED PRODUCT OR HAVING THE LABEL FITTED THEREON

摘要

The present invention provide a heat-shrinkable film consisting of a layer or comprising at least one layer, wherein the layer is made of a mixed resin containing a polylactic acid resin and a polyolefin resin as the main components, wherein mass ratio of the polylactic acid resin and the polyolefin resin is 95/5 to 50/50 by mass, the polylactic acid resin being a copolymer of D-lactic acid and L-lactic acid or a mixed resin of the copolymer, wherein D/L ratio of D-lactic acid and L-lactic acid is 3/97 to 15/85 or 85/15 to 97/3, the storage elastic modulus (E′) of the polyolefin resin or the soft acrylic resin at 20 degree C. being 100 MPa or less as measured at an oscillation frequency of 10 Hz and a strain of 0.1%, the film being stretched in at least one direction, and the heat shrinkage ratio of the film in the main shrinking direction being 20% or more as measured after the film is immersed in hot water of 80 degree C. for 10 seconds.;The heat-shrinkable film exhibits excellent heat-shrinkable property, impact resistance, transparency, mechanical property, and shrink finishing quality; it is applicable to shrinkable packing, shrinkable bond-packing, shrinkable label and the like.
