In heat-shrinkable polyester films, the content of 1,4-cyclohexane dimethanol is 10 to 50 % by mole based on the polyhydric alcohol component and that the heat shrinkage factors of a 10 cm square sample of the films in (A) hot water of 75 °C, (B) hot water of 85 °C, and (C) hot water of 95 °C are 30 to 40 %, 50 to 60 %, and 65 to 77 %, respectively. The films can be produced by drawing under specified conditions.

La présente invention concerne des films en polyester thermorétractables qui se caractérisent en ce que leur teneur en 1,4-cyclohexanediméthanol est comprise entre 10 et 50 % par mole sur la base du constituant polyol et en ce que les facteurs de thermorétractabilité d'un échantillon de 10 cm<2> du film dans (A) de l'eau chaude à 75 DEG C, (B) de l'eau chaude à 85 DEG C, et (C) de l'eau chaude à 95 DEG C sont respectivement de 30 à 40 %, de 50 à 60 % et de 65 à 77 %. Ces films peuvent être produits par étirement dans des conditions spécifiées.
