Abstract

Feuils fabriqués en polyéthylènes et en matériaux de charge, et articles fabriqués à partir de ces feuils, présentant une vitesse supérieure de transmission de vapeur d'eau (WVTR) par rapport aux feuils actuels basés sur des polyéthylènes classiques de Zeigler-Natta. On produit ces polyéthylènes dans un processus comportant un catalyseur de métallocène. On peut fabriquer les feuils au moyen d'un procédé de coulage et leur conférer une teneur en charge extrêmement variable, en général, selon des rapports entre polyéthylène et charge de 30/70 à 70/30. Ces polyéthylènes à base de métallocène, quand on les combine à une charge, permettent également l'extrusion de feuils plus minces, ce qui permet d'obtenir des feuils plus légers et plus mous. Les m-polyéthylènes utilisés pour fabriquer ces feuils présentent généralement un indice de largeur de répartition de composition supérieur à 50 %, un M¿w?/M¿n? inférieur à 3 et un M¿z?/M¿w? inférieur à 2.
