Abstract

Cette invention concerne une feuille de polymère servant à produire un opercule pelable thermocollé, sac ou sachet thermo-soudé ; et un procédé de production associé. La feuille de polymère comprend une couche inférieure thermocollable comprenant des polyoléfines et des additifs, une couche intermédiaire comprenant une couche support polymère et une couche supérieure thermorésistante comprenant un polyamide. La feuille de polymère est produite lors d’un procédé d’extrusion simple, extrudant simultanément au moins une couche polymère thermocollable et au moins un polyamide.
