Films based on filled polyethylene and EVA resin, weldable using high frequency, and products obtained by the use of these films

摘要

The film is composed of an initial polyethylene resin containing from 8 to 18 % of EVA, of a polypropylene resin and of a neutral filler which makes it possible to reduce tackiness to the touch and to increase the rigidity of the film without appreciably impairing its weldability using high frequency. It makes it possible to obtain articles by high-frequency welding assembly and mechanical cutting.
