Abstract

L'invention concerne un film coulé multicouche comprenant une couche autocollante, une couche antiadhésive et au moins une couche centrale disposée entre la couche adhérente et la couche antiadhésive et en contact avec celles-ci. La couche autocollante comprend un polyéthylène ultra basse densité (ULDPE), un interpolymère de propylène, ou des mélanges de ceux-ci. La couche antiadhésive comprend un premier polyéthylène linéaire basse densité (premier LLDPE) possédant une densité de 0,915 à 0,938 g/cm3 et un indice de fusion de 0,5 g/10 min à 10 g/10 min. Chacune des couches centrales comprend un second polyéthylène linéaire basse densité (second LLDPE) possédant une densité de 0,905 à 0,930 g/cm3 et un indice de fusion de 0,5 g/10 min à 10 g/10 min. Le film coulé multicouche comprend de 3 % en poids à 7 % en poids, sur la base d'une quantité totale de polymères présents dans le film coulé multicouche, du polyéthylène basse densité (LDPE).
