Title (EN) MULTI-LAYER FILM
(FR) FILM MULTICOUCHE
Abstract:
(EN) The present invention concerns a multi-layer film comprising at least five layers, comprising two outer layers, at least one core layer and at least one intermediate layer located between each outer layer and the core layer, wherein both outer layers comprise linear low density polyethylene substantially free of long chain branching and having a density above 915 kg/m3, wherein the amount of linear low density polyethylene in at least one or in both outer layers is preferably at least 60% by weight based on the total weight of the respective layer and at least one of either the core layer or at least one intermediate located between each outer layer and the core layer consists essentially of polyolefins and comprises high density polyethylene.
(FR) La présente invention concerne un film multicouche comprenant au moins cinq couches, comprenant deux couches externes, au moins une couche centrale et au moins une couche intermédiaire située entre chaque couche externe et la couche centrale, les deux couches externes comprenant du polyéthylène de faible densité linéaire sensiblement exempt de ramification à chaînes longues et ayant une densité supérieure à 915 kg/m3, la quantité de polyéthylène de faible densité linéaire dans au moins une ou les deux couches externes étant de préférence au moins 60 % en poids sur la base du poids total de la couche respective, et au moins une parmi la couche centrale ou au moins une couche intermédiaire située entre chaque couche externe et la couche centrale étant essentiellement constituée de polyoléfines et comprenant du polyéthylène à haute densité.
