FIELD: food industry.
SUBSTANCE: invention is intended for usage in food industry, in particular, for manufacture of food products casings from film. The tubular film is manufactured from a polymer composition containing thermoplastic polyester having complex shear viscosity η* equal to at least 3000 Pa·s according to measurement in accordance with ISO 6721-10:1999 publication at 240°C and 0.1 radian per second.
EFFECT: tubular film for food products casing has less modifications in terms of geometric parameters, is characterised by a lower frequency of interruptions in the process of the casing manufacture; additionally, the casing can stretch during usage of standard equipment and conditions.
