Title (EN) POUCH FOR PACKAGING FLOWABLE MATERIALS
(FR) SAC UTILE POUR LE CONDITIONNEMENT DE MATIERES FLUIDES
Abstract:
(EN) An environmentally friendly polymer film pouch made from a homogeneously branched linear ethylene interpolymer film structure for the packaging of flowable materials such as milk, is disclosed. A pouch made from a multilayer film structure such as a two-layer or a three-layer coextruded film containing at least one seal layer of a homogeneously branched linear polyethylene is also disclosed. A process for making a pouch for packaging flowable materials using a homogeneously branched linear ethylene interpolymer film structure is also disclosed.
(FR) L'invention concerne un sac en film polymère sans danger pour l'environnement constitué d'une structure de film interpolymère d'éthylène linéaire ramifié homogène, qui est utile pour le conditionnement de matières fluides telles que le lait. L'invention concerne également un sac constitué d'une structure de film multicouches, tel un film coextrudé à deux ou à trois couches qui contient au moins une couche de soudage en polyéthylène linéaire ramifié homogène. L'invention concerne également un procédé de fabrication du sac utile pour le conditionnement de matières fluides, qui emploie une structure de film interpolymère d'éthylène linéaire ramifié homogène.
