An oriented heat sealable multilayer structure. The structure comprises a substrate having a first surface and a second surface, the substrate comprising a polyolefin film; a polymeric heat sealable layer on the first surface of the substrate, the layer comprising a polymeric material selected from the group consisting of a terpolymer of ethylene, propylene and butene-1, a random copolymer of ethylene and propylene, and blends thereof; a primer coating on the second surface of the substrate; and a water vapor and gas barrier layer on the primer coating, the water vapor and gas barrier layer selected from the group consisting of a vinylidene chloride copolymer containing at least about 50% of vinylidene chloride and an interpolymer comprising a minor amount of acrylic acid, methacrylic acid or mixtures thereof and a major amount of neutral monomer esters comprising methyl acrylate, ethyl acrylate, methyl methacrylate or mixtures thereof. A method for producing the heat sealable multilayer film structure is also provided.

Structure multicouche orientée, scellable à chaud. La structure est composée : d'un substrat possédant une première et une seconde surfaces, le substrat étant constitué d'une pellicule polyoléfinique; d'une couche polymérique scellable à chaud sur la première surface du substrat, la couche renfermant un matériau polymérique choisi parmi un terpolymère d'éthylène, de propylène et de but-1-ène, un copolymère statistique d'éthylène et de propylène et leurs mélanges; d'un revêtement primaire sur la seconde surface du substrat; d'une couche de vapeur d'eau et de barrière pour les gaz, choisie parmi un copolymère de chlorure de vinylidène contenant au moins 50 % environ de chlorure de vinylidène, et un interpolymère comprenant une quantité mineure d'acide acrylique, d'acide méthacrylique ou de leurs mélanges, et une quantité majeure d'esters monomères neutres, comprenant l'acrylate de méthyle, l'acrylate d'éthyle, le méthacrylate de méthyle, ou leurs mélanges. On divulgue également une méthode pour produire la structure pelliculaire multicouche, scellable à chaud.
