FIELD: chemistry.
SUBSTANCE: invention refers to production technique of barrier layered polymer films. Single- or laminate film consists of, at least, one gaseous oxygen proof barrier layer. Layer is basically laminated with mixed ethylene copolymer and vinyl alcohol and, at least, one multipolyamide. Film is applied for packaging of perishable, outgassing products, such as foodstuffs. Packing made of this film for perishable, outgassing products represents first of all a package for cheese making its aging. The film possesses is minimum possible permeability almost independent of moisture content in packed product and/or in environment, thus ratio of carbon dioxide permeability and oxygen permeability is not less 3:1.
EFFECT: production of polymer film possessing minimum possible permeability almost independent of moisture content in packed product and/or in environment.
