Title
(EN) MULTILAYER BARRIER SHRINK FILM
(FR) FILM ISOLANT RETRACTABLE MULTICOUCHES
Abstract
(EN)
A multilayered packaging film includes a first exterior layer of a heat sealable polymer and second exterior layer on a side opposite from the first exterior layer, and including two inner layers made of polyvinylidene chloride disposed between the first and second layers and an innermost core layer disposed between the two inner layers wherein the innermost core layer is not crossed-linkable when exposed to radiant energy.
(FR)
La présente invention concerne un film d'emballage multicouches comprenant une première couche extérieure constituée d'un polymère thermoscellable, une seconde couche extérieure sur un côté opposé à la première couche extérieure, et deux couches internes constituées de chlorure de polyvinylidène disposées entre les première et seconde couches, et une couche de base placée entre les deux couches internes, cette couche de base n'étant pas réticulable lors d'une exposition à une énergie de rayonnement.
