FIELD: food industry.
SUBSTANCE: invention relates to the field of food packaging and concerns a vacuum-sealed plastic bag that decomposes naturally. The package has a package base, which consists of layers compounded from several film layers, and, in the middle of the said package base, a receiving cavity is formed, used for storing food products, and at least one of the film layers contains a material that promotes decomposition, and in the film material for preparation and production of these several layers, polyethylene is contained, and the amount of the added substance that promotes decomposition is about 5% by weight of polyethylene.
