Title
(EN) FORMABLE POLYESTER FILMS
(FR) FILMS DE POLYESTER POUVANT ÊTRE MIS EN FORME
Abstract
(EN)
A formable biaxially-oriented film includes a first layer. The first layer includes from about 10 to about 90 wt.% crystalline polyester and from about 10 to about 90 wt.% of a formability enhancer to assist in increasing the polymeric chain flexibility. The formability enhancer has a melting point less than about 230°C. The film has a MD and a TD Young's Modulus of at least 10% lower than a crystalline polyester film in the absence of the formability enhancer. The film may further include a second layer, which includes an amorphous copolyester. The second layer may be adjacent to or attached to the first layer.
(FR)
Un film à orientation biaxiale pouvant être mis en forme comprend une première couche. La première couche contient d'environ 10 à environ 90 % en poids de polyester cristallin et d'environ 10 à environ 90 % en poids d'un agent d'amélioration d'aptitude au formage de façon à favoriser l'augmentation de la flexibilité d'une chaîne polymère. L'agent d'amélioration d'aptitude au formage a un point de fusion inférieur à environ 230 °C. Le film a un module de Young MD et un module de Young TD inférieurs d'au moins 10 % à ceux d'un film de polyester cristallin ne contenant pas d'agent d'amélioration d'aptitude au formage. Le film peut en outre comprendre une seconde couche qui contient un copolyester amorphe. La seconde couche peut être adjacente à la première ou fixée à celle-ci.
