Abstract

A paper-like material is produced by extruding through slit having a thickness of 0,3-3 mm. a mix having a temperature of 200 DEG -350 DEG C. and comprising polypropylene, which has been produced in the presence of a stereospecific catalyst, and calcium carbonate, silica, or sodium silicate, stretching the still plastic extruded film 2-6 times, and quenching at a distance of 2-10 cm. from the extrusion head in a water bath at a temperature of 0 DEG -30 DEG C. Silica may have a particle size of 0,015-0,020 microns. Calcium carbonate or sodium silicate may have a particle size of 1-100m . Examples are given.
