Abstract

La présente invention concerne un film MDO de polyéthylène stratifié comprenant des quantités élevées d'un copolymère d'éthylène spécifique ayant une large distribution de poids moléculaire dans une couche. Ce film présente une rigidité élevée et d'excellentes propriétés d'adhérence. L'invention concerne en outre un film barrière comprenant une couche métallique ou un revêtement barrière et le film MDO de polyéthylène stratifié susmentionné, un procédé de formation d'un film barrière à partir dudit film MDO de polyéthylène stratifié, un stratifié, et un article comprenant le film barrière.
