Abstract
A film comprising a core layer (5), first and second outer layers (3, 4), first and second intermediate layers (1, 2). The core layer (5) contains at least 50% by weight of a ULDPE. At least one of the outer layers (3, 4) contains at least 50% by weight of a LLDPE. The first and/or second intermediate layer (1, 2) is made of a first composition based on EVA and on a copolymer of ethylene and of at least one compound selected from the group consisting of the linear alkenes of order C greater than ethylene, dienes and cyclic alkenes.
Claims33
A film comprising a polyethylene-based core layer, first and second polyethylene-based outer layers on either side of the core layer, at least one first intermediate layer between the core layer and the first outer layer and at least one second intermediate layer between the core layer and the second outer layer, wherein:
- the core layer contains at least 50% by weight of a ULDPE polyethylene,
- at least one of the first and second outer layers contains at least 50% by weight of a LLDPE polyethylene, and
- said first and/or second intermediate layer is made of a first composition based on EVA and a copolymer of ethylene and at least one second compound selected from the group consisting of linear alkenes of order Cn greater than ethylene, dienes and cyclic alkenes.
