Abstract

Ce stratifé multicouche comprend: (A) une couche préparée à partir d'un copolymère aléatoire d'éthylène avec une cyclo-oléfine spécifiée, telle que tétracyclododécène, ou à partir d'une résine de cyclo-oléfine produite par greffage du copolymère mentionné ci-dessus, ou une couche préparée à partir d'une composition de résine de cyclo-oléfine contenant la résine de cyclo-oléfine mentionnée ci-dessus et une polyoléfine; et (B) une couche d'un polymère ayant une perméabilité à l'oxygène égale ou inférieur à 10 cc(STP).mm/m<2>.24h.atm, déterminée à une température de 23 DEG C et à une humidité relative de 0 %. Ce stratifé possède un coefficient de pénétration de l'humidité inférieur à 0,2 g.mm/m<2>.24h.atm, ainsi qu'une perméabilité à l'oxygène inférieure ou égale à 5 cc(STP).mm/m<2>.24h.atm, et il possède d'excellentes propriétés de barrière contre les gaz et une excellente rigidité. Cette invention se rapporte également à un matériau d'emballage produit à partir de ce stratifié ainsi qu'à un film.
