PURPOSE:To produce the package excellent in heat shrinkability by using the copolymerized polyester containing a specified compound for the package. CONSTITUTION:The compound shown by a formula(1) is copolymerized with the terephthalic acid and ethylene glycol as main components, and a copolymerized polyester film is obtained. The copolymerized polyester film is drawn longitudinally and transversely, whereby the drawn film in which the heat shrinkability in the hot blast of 100 deg.C, is 30% or more at least in one direction of the longitudinal and width directions of the film, is obtained. The obtained film shows excellent heat shrinkability, and generates no shrinkage spot or no density spot in a print, and further is excellent in beauty feeling in application test, also. |
