Abstract

Sachet constitué d'un film polymère sans danger pour l'environnement, produit à partir d'une structure sous forme de film polyéthylène, destiné à l'emballage de matières fluides, par exemple de lait. Ledit sachet comporte par exemple une structure sous forme de film à une seule couche ou à plusieurs couches, telle qu'un film coextrudé à deux ou trois couches comprenant au moins une couche constituée d'un mélange d'un copolymère linéaire d'éthylène et d'un polyéthylène à haute pression et à faible densité en tant que couche de fermeture étanche. La présente invention concerne également un procédé permettant de fabriquer un sachet destiné à l'emballage de matières fluides à l'aide d'une structure sous forme de film constituée d'un mélange de copolymère linéaire d'éthylène et d'un polyéthylène à haute pression et à faible densité.
