FIELD: food industry. n SUBSTANCE: shell represents a multilayer film having at least one thermoplastic polyamide-containing layer and at least one adhesive layer comprising a functionalized predominantly hydrocarbon (co)polymer. Each of the polyamide-containing layers is made of a composition comprising: a) 5 to 95% of at least one (co)polyamide and b) 95 to 5% of at least one component selected from the list comprising water-insoluble highly permeable to water vapours thermoplastic (co)polymers and water-soluble (co)polymers. n EFFECT: shell is pervious to moisture in conditions of hot smoking, but keeps the moisture within at relatively low temperatures ranging usually from 6 degrees or below, which allows to effectively smoke a food product, and store it with excellent consumer properties preservation and low mass losses. n 37 cl, 3 tbl, 5 ex |
