Abstract

L'invention concerne un contenant de produit en vrac flexible pourvu d'un espace de logement de contenant délimité par des parois, les parois étant composées au moins en partie d'un matériau en feuille multicouche et au moins deux couches de feuille étant constituées d'une matière plastique, entre lesquelles est insérée une couche et/ou une couche intermédiaire constituée d'un matériau éliminant les charges électrostatiques, et au moins la couche de feuille intérieure en matière plastique tournée vers le produit en vrac étant pourvue d'une perforation débouchant sur la couche et/ou la couche intermédiaire constituée du matériau éliminant les charges électrostatiques. L'objet de l'invention est de perfectionner ledit contenant. À cet effet, la perforation est réalisée sous la forme d'une perforation laser présentant un motif de trou de perforation, chaque canal de trou se rétrécissant en section transversale de la face intérieure de la couche de feuille intérieure, laquelle face est tournée vers le produit en vrac, à la couche et/ou à la couche intermédiaire constituée du matériau éliminant les charges électrostatiques.
