摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a heat-shrinkable film that has a light environmental load, is excellent in heat-shrinking properties, impact resistance, transparency, mechanical properties and shrinking finish properties, and is suitable for applications such as shrink packaging, shrink bundling packaging or shrinkable labels. <P>SOLUTION: The heat-shrinkable film is composed of a mixed resin comprising as main components a polylactic acid resin and a soft acrylic resin with a mass ratio of the polylactic acid resin to the soft acrylic resin of 95/5-50/50 or has at least one mixed resin layer, where the polylactic acid resin comprises a copolymer of D-lactic acid and L-lactic acid or a mixed resin comprised of the copolymer while the soft acrylic resin has a storage elastic modulus (E') of at least 0.1 MPa and at most 100 MPa at 20°C as measured with an oscillation frequency of 10 Hz and has a heat shrinkage factor of at least 20% in the main shrinking direction when stretched at least in one direction and immersed in hot water of 80°C for 10 sec. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
