THERMALLY SHRINKABLE POLYOLEFIN FILM, MOLDED ARTICLE USING THE FILM, THERMALLY SHRINKABLE LABEL, AND CONTAINER

The present invention provides a polyolefin series heat-shrinkable film comprising a mixed resin mainly containing a polyolefin series resin (A), polylactic acid series resin (B), and a resin (C) facilitating compatibility with the resin (A) and the resin (B), or comprising at least one layer made of the mixed resin, wherein mass ratio of the resin (A) to the resin (B) is (A)/(B) = 99/1 to 70/30; heat shrinkage ratio of the film at least in one direction when dipped in hot water at 80°C for 10 seconds is 20% or more; and natural shrinkage ratio of the film when stored at 40°C under 50% RH environment for 7 days is less than 10%. This polyolefin series heat-shrinkable film exhibits excellent heat-shrinkable property and shrink finishing quality, and inhibits natural shrinkage. This invention also provides a polyolefin series heat-shrinkable label and container on which the heat-shrinkable label is fitted.
