Abstract:
1. A soft 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, said first and/or second intermediate layer is made of a first composition based on an ethylene vinyl acetate copolymer and a copolymer of ethylene and at least one second compound selected from the group consisting of linear alkenes of order C the thickness of said first or second intermediate layer is less than 15% of the total thickness of the film, and the melting point of the core layer and of said first and second intermediate layers are each less than 100° C.
