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

摘要

Disclosed is a thermally shrinkable polyolefin film which comprises a mixed resin mainly composed of a polyolefin resin (A), a polylactic acid resin (B) and a resin (C) capable of improving the compatibility between the resin (A) and the resin (B) or has at least one layer comprising the mixed resin, wherein the ratio of the resin (A) to the resin (B) ((A)/(B)) is 99/1 to 70/30 by mass. The film has a thermal shrinkage ratio in at least one direction of 20% or higher as determined after immersing the film in hot water of 80°C for 10 seconds, has a natural shrinkage ratio of less than 10% as determined after storing the film for 7 days under environment of 40°C and 50% RH, is excellent in thermal shrinking properties and shrinkage finishing, and is reduced in natural shrinking. Also disclosed is a thermally shrinkable polyolefin label. Further disclosed is a container having the label thereon.
