FIELD: food industry, packing materials. SUBSTANCE: films or sheets were made of polymeric olefin-base composition consisting of (a): 10-50 p. p. propylene homopolymer at stereoregularity index above 80, or copolymer of propylene with ethylene and/or other alpha-olefin containing above 80% propylene at index above 80; (b) 5-20 p. p. semicrystalline copolymer fraction that is insoluble in xylene at the room temperature or environment temperature; and (c) 40-80 p. p. copolymer fraction of ethylene with propylene and/or other alpha-olefin and optionally small amount of diene. The indicated fraction of copolymer has less 40% ethylene and/or other alpha-olefin, it is soluble in xylene at the room temperature and shows intrinsic viscosity 1.5-4 dl/g. The obtained extruded films and sheets and lamellar plates have at least one layer as film or sheet described above. Other films or sheets were made of mixtures of polymeric olefin-base composition and other olefin-base polymer. Articles made of the indicated material were used in food and chemical industry, in medicine. EFFECT: improved quality of material. 16 cl, 3 tbl
