摘要： PURPOSE: A heat-shrinkable polyester-based film is provided to secure print-processing properties, mechanical strength, and heat resistance and to control the change of a thermal shrinkage rate. CONSTITUTION: A heat-shrinkable polyester-based film has a 1.5~3 change rate by the temperature of the heat shrinkage rate to the main contraction direction in 60~70 deg C. The film is produced from a copolymerized polyester composition including diethylene glycol as a diol component. The copolymerized polyester composition includes a dibasic acid component with more than 90mol% of terephthalic acid, and the diol component with 3~16mol% of diethylene glycol, 10~25mol% of neopentyl glycol, and 59~86mol% of ethylene glycol.

摘要： PURPOSE: A heat-shrinkable polyester film is provided to prevent the film from unevenly shrunk and to obtain excellent transparency, adhesive force with a solvent, mechanical strength to the longitudinal direction of the film, and crack resistance. CONSTITUTION: A heat-shrinkable polyester film includes ethylene terephthalate as a main repeating unit. The polyester film is stretched in the longitudinal direction of the film. The phase difference in a plane is 4000-4400 nm. The percentage of contraction of the film is less than 20% when the film is maintained at warm water of 70 °C for 10 seconds and the percentage of contraction is more than 40% when the film is maintained at warm water of 90 °C for 10 seconds.
