FIELD: packing. SUBSTANCE: oxygen absorbing system is provided. Proposed multiplayer polymer film for packing materials sensitive to oxygen includes a) first polymer layer with oxygen-absorbing material containing polymer material with oxidation centers and forming at least one by-product at its interaction with oxygen, and b) second layer made from thermoplastic and separated from first layer and including effective amount of neutralizing material chosen from group consisting of inorganic and organic bases where neutralizing material is cable of at neutralizing by-products formed interaction of oxygen-absorbing material and oxygen. Proposed system is used in multiplayer films including oxygen-absorbing layer. Invention provides description of package made from such film and packing articles. EFFECT: increased degree of oxygen absorption, possibility of usage with materials sensitive to oxygen. 30 cl, 1 tbl, 1 dwg
