PROBLEM TO BE SOLVED: To obtain a heat-shrinkable polyester-based laminated film that has excellent transparency, glossiness, processing suitability and slipperiness and is easily produced. SOLUTION: The heat-shrinkable polyester-based film has a haze of≤2%, glossiness≥190% at a measurement angle of 45°for at least one side, a dynamic friction coefficient between films at an arbitrary position of≤1.5 and a shrinkage percentage of≥40% in the main shrinkage direction when immersed in hot water at 95°C for 10 seconds. More preferably the heat-shrinkable polyester-based film has a low haze and high glossiness even after hot water treatment and excellent solvent bonding strength. COPYRIGHT: (C)2009,JPO&INPIT |
