Abstract

a. Procédé pour préparer un film en polyester thermoplastique étiré biaxialement par étirage biaxal simultané d'un film en polyester thermoplastique par la méthode de séchage sous tension. b. Il se caractérise en ce qu'on étire ledit film à température d'étirage supérieure à la température de transition vitreuse du polyester thermoplastique en maintenant la température de préchauffage à une valeur supérieure à celle de la température d'étirage, juste avant l'étirage et en maintenant la température de traitement à la chaleur à une valeur inférieure à celle de la température de préchauffage, juste après l'étirage et qu'on effectue un traitement de recuisson en plusieurs stades en élevant la température respectivement dans chaque stade suivant des intervalles de températures sensiblement égaux. c. Application notamment dans le domaine de bandes magnétiques, des condensateurs, des fils métallisés et des emballages alimentaires.
