FIELD: food industry.
SUBSTANCE: invention relates to a tubular multilayer thermoplastic shell for food products which contains an outer layer (Z), an inner layer (I) and at least one layer (P) located between them which contains coarse-grained nonorganic and/or organic particles and more than 50% (by weight) of at least one thermoplastic polymer. At least one sort of the coarse-grained particles has average diametre of equivalent ball d50 exceeding 5 mcm while the surface of the outer layer (Z) and/or inner layer (I) has average (based on results of 5 measurements) profile irregularity height Rz equal to at least 5 mcm. Furthermore, the invention relates to a method of production of the said shell for food products.
EFFECT: according to the invention idea the shell is basically or completely identical to natural, collagenic, skin and fibrous or fibre-reinforced cellulose shell in terms of appearance and has larger stability and low level of manufacturing defect.
