Abstract

L'invention concerne des feuilles transparentes consistant en polyhexaméthylène-isophtalamide d'épaisseur 10 à 1 000 mu . Ces feuilles sont par exemple préparées par extrusion ou soufflage. Faible perméabilité à la vapeur d'eau. Bonnes caractéristiques d'étirage.Disclosed are transparent sheets consisting of polyhexamethylene-isophthalamide having a thickness of 10 to 1000 µm. These sheets are for example prepared by extrusion or blow molding. Low permeability to water vapor. Good stretching characteristics.
