The film comprises a central layer, composed of a mixture of radical low density polyethylene and of conventional linear polyethylene, sandwiched between two outer layers comprising at least 50% by weight of conventional linear polyethylene, with a relative density of 0.918-0.930, which are devoid of metallocene linear polyethylene, each of the outer layers having a thickness representing 5 to 25% of the total thickness of the film.
