Abstract

L'invention concerne un film polymère qui comprend trois couches. La première couche contient un mélange d'un copolymère d'éthylène-vinyl acétate, d'un polyéthylène linéaire à faible densité et d'un second copolymère d'éthylène-vinyl acétate. La deuxième couche contient le copolymère d'éthylène-vinyl acétate et la troisième couche contient un mélange de polyéthylène linéaire à faible densité et un polyéthylène à faible densité, la deuxième couche étant placée entre la première et la troisième couche, et chacun des éléments parmi un concentré coloré, un agent glissant et un additif antiadhérent pouvant éventuellement et indépendamment être présent dans la première, la deuxième et la troisième couche.
