Abstract
Procédé de fabrication d'une feuille en polypropylène, biaxialement étirée et présentant une rugosité améliorée, qui consiste à extruder, à l'aide d'une filière plate, un mélange fondu de polypropylène ou d'un copolymère de propylène et d'une autre alpha -oléfine, puis à diriger ce produit sur un cylindre refroidisseur en vue de constituer ainsi une préforme solide, orthogonalement étirée, éventuellement thermofixée, caractérisé en ce que, pour réaliser la préforme, c'est-à-dire au moment de la coulée du mélange fondu, on règle la température de cristallisation du polymère (t c ) à une température inférieure ou égale à 80 degrés C/sec. et le temps pendant lequel la température superficielle de la coulée évolue entre tc et (tc - 20 degrés C) à au moins 1/3 de seconde.
