FIELD: processing plastics. SUBSTANCE: two polymers are extruded together and then cooled. Thus prepared intermediate product is irradiated with the help of beam of accelerated electrons, angle between said intermediate product and axis of electron beam being 15-60 degrees. Maximal path of electrons is 1-4 times of thickness of polymer layer being turned to said beam. Then thus treated article is oriented. EFFECT: improves efficiency of method. 1 dwg, 1 tbl
