Abstract

L'objectif de la présente invention est de concevoir un film stratifié facile à retirer dans lequel aucun phénomène de formation de fils ne se produit et le détachement d'un stratifié ou la cassure du film ne se produit pas lorsque la température de thermoenduction est accrue, et qui présente une performance de facilité de retrait constante. La présente invention concerne : un film stratifié facile à retirer caractérisé en ce qu'il comprend une couche appliquée à chaud et une couche de support, la couche appliquée à chaud comprenant une composition de polyoléfine (D) comprenant 20 à 70 % en poids d'un polymère propylène (A), 20 à 60 % en poids d'un polymère éthylène (B) et 5 à 40 % en poids d'un copolymère (éthylène)-(α,β-acide carboxylique insaturé) (C), et la couche de support comprenant un copolymère séquencé propylène (E). L'objectif de la présente invention est également l'utilisation du film stratifié facile à retirer.
