FIELD: packing industry.
SUBSTANCE: casing is produced by the coextrusion of at least two layers including the outer layer (Z). At least one layer which is not an outer one (Z) contains more than 50 wt % of thermoplastic components on the (co)polyamide(s) basis. The outer layer (Z) contains more than 50 wt % of thermoplastic components and inorganic particles distributed in them with at least part of the particles having the diametre of the equivalent sphere exceeding 20 mcm. At least one of the layers (not the outer one (Z)) performs the carrying function.
EFFECT: as per their appearance and roughness the obtained casings for food products are similar to the collagen, protein, reinforced with fibers cellulose and natural casings.
