Title
(EN) ENCAPSULATED BARRIER FOR FLEXIBLE FILMS AND A METHOD OF MAKING THE SAME
(FR) BARRIERE ENCAPSULEE POUR FILMS FLEXIBLES ET SON PROCEDE DE FABRICATION
Abstract
(EN)
Coextruted films having a heat a sensitive barrier layer (110) comprising materials such as EVOH, nylon etc, which has been encapsulated by a first adhesive material (112), and additional adhesive layers of a higher melting polymer (113) deposited on the first adhesive layer. The first adhesive layers help to protect the heat sensitive barrier material from the heat of extrusion/lamination.
(FR)
L'invention concerne des films coextrudés présentant une couche barrière (110) thermosensible comprenant des matériaux tels que de l'EVOH, du nylon etc.., qui a été encapsulée par une première matière adhésive (112), et des couches adhésives additionnelles d'un polymère à point de fusion supérieur (113) déposées sur la première couche adhésive. Les premières couches adhésives aident à protéger le matériau barrière thermosensible de la chaleur provenant de l'extrusion/lamination.
