FIELD: chemistry.
SUBSTANCE: invention relates to an oxygen impermeable polyolefin composition for use in making food packaging. The composition contains polyolefin, whose composition includes a copolymer of ethylene with a vinyl alcohol containing 27-44 mol % ethylene links, an active oxygen absorbent, a miscibility enhancing additive, as well as clay or a nucleating agent or a polyamide, optionally including said clay or nucleating agent. The clay has characteristic ratio of at least 10.
EFFECT: combining components in a defined ratio enables to obtain compositions with unexpectedly good properties as an oxygen barrier.
