Abstract
L'invention concerne l'industrie des produits d'emballage. Elle a pour objet des pellicules qui peuvent être rendues thermorétrécissables par orientation-étirage. Ces pellicules comprennent au moins trois couches, notamment une couche intérieure sensiblement non orientée et de préférence soufflée à chaud formée d'un polymère d'éthylène, ainsi qu'une couche orientée de polyester ou de copolyester. Ces pellicules sont préférées pour le remplacement des pellicules de poly(chlorure de vinyle) pour la confection des emballages.
