Abstract

Process for the production of a foamed polyolefin film characterized in that it comprises extruding a mixture containing between 60% and 90% by weight of low-density polythene and between 40% and 10% by weight of a crystalline polyolefin, said mixture containing an agent. blower, the gas evolution temperature of the blowing agent being followed by committing the surface of the foamed film to a treatment to improve the binding properties of its surface.
