<P>PROBLEM TO BE SOLVED: To provide a heat-shrinkable polyester film excellent in all of the properties of perforation tearableness when labeled, strength at an adhesive part, impact resistance, designedness when mounted to bottles, slipperiness between labels after applied to bottles. <P>SOLUTION: The heat-shrinkable polyester film contains a silicone constituent at least on an outermost layer of one side, has a shrinkage ratio in one direction (y direction) of not less than 20% and less than 85% after immersed in a hot water of 95°C±0.5°C for 10 seconds, a shrinkage ratio in the direction (x direction) orthogonal to it of not less than 0% and not greater than 10%, and a refractive index in the thickness direction (z direction) of less than 1.5400. <P>COPYRIGHT: (C)2008,JPO&INPIT |
