Abstract
The present invention relates to a film comprising at least one layer (A) of a mixture of polyamide and polyethylene, and optionally a layer (B) of polyethylene, such that if the polyethylene, of the layer (A) is not a metallocene polyethylene then the layer (B) is obligatory and essentially consists of metallocene polyethylene. These films are used for the moulding of polyesters, for fumigation or for the manufacture of packaging.
