Abstract

L'invention concerne l'industrie de l'emballage. Elle a pour objet une pellicule stratifiée de nylon et de polymère d'oléfine Cette pellicule stratifiée comprend au moins trois couches, à savoir 1 une couche de nylon, 2 une couche de copolymère d'éthylène et d'acétate de vinyle comme adhésif et 3 une couche de polymère d'oléfine, qui est de préférence de polyéthylène. La pellicule est irradiée de préférence jusqu'à une dose de 2,0 à 6,0 mégarads. Cette pellicule est préférée pour l'emballage des aliments qui doivent être cuits à l'eau chaude.The invention relates to the packaging industry. It relates to a laminated film of nylon and olefin polymer This laminate film comprises at least three layers, namely 1 a layer of nylon, 2 a layer of ethylene vinyl acetate copolymer as an adhesive and 3 a layer of olefin polymer, which is preferably polyethylene. The film is preferably irradiated up to a dose of 2.0 to 6.0 megarads. This film is preferred for wrapping foods which are to be cooked in hot water.
