A method of producing a multilayer polymeric film is accomplished through the vapor deposition of a barrier coating onto an ethylene vinyl alcohol copolymer layer, which is adhered to a polymeric substrate. A multilayer polymeric film exhibiting barrier characteristics is also accomplished through the use of an ethylene vinyl alcohol copolymer layer between a vapor deposited barrier coating and a polymeric substrate.
La présente invention, qui concerne un procédé de production d'un film polymère multicouche, consiste à réaliser un revêtement barrière par dépôt en phase vapeur sur une couche de copolymère éthylène - alcool vinylique adhérant à un substrat polymère. On obtient également un film polymère multicouche à caractéristiques de barrière en ayant recours à une couche de copolymère éthylène - alcool vinylique disposée entre un substrat polymère et un revêtement barrière réalisé par dépôt en phase vapeur.
