FIELD: food industry.
SUBSTANCE: invention relates to flat or sleeve-type cover or film suitable for smoking and intended for packaging of food products such as sausage cover, shrink film wrapper and etc., on polymer basis. This cover or film was first produced by air exhausting from homogenous plastic melt consisting of plastics mixture. This melt includes, at least, polyamide, PVAL (polyvinyl alcohol) and PEBAX (polyetherblockamide). Food cover or film is characterized by permeability factor by water steam being at least 1 kg/m2 in 24 hours. Oxygen permeability at 30 μm thickness of film is less 2.1 sm3/m2 in 24 hours. Besides, method of such items production is proposed in this invention for the first time.
EFFECT: development of effective and economical method of polyethylene food film production provided with possibility of further automated treatment.
