Abstract
(EN)
A method for producing a cellulose acylate film is provided and includes: casting a cellulose acylate solution onto a support to form a cellulose acylate film; peeling the cellulose acylate film from the support; and stretching the cellulose acylate film, the cellulose acylate film in the stretching having a temperature of 140 to 250°C.
(FR)
La présente invention a trait à un procédé pour la production de film à base d'acrylate cellulosique comprenant: la coulée d'une solution d'acétate cellulosique sur un support pour la formation d'un film à base d'acylate cellulosique; la séparation du film à base d'acylate cellulosique du support; et l'étirage du film à base d'acylate cellulosique, le film à base d'acylate cellulosique lors de l'étirage ayant une température comprise entre 140 et 250 °C
