Abstract

Process for producing foils or films of plastic material with increased surface friction. According to the invention, two or more foils are extruded, laminated and stretched together, the supply of material (6) to the extrusion of the foil or foils which are to form the surface layer (7) being controlled in such a way that the amount of plastic material is insufficient to form a coherent layer when the laminated foil is stretched. In this way the surface layer (7) will break at stretching and give a rough surface with an increased surface friction.
