CASING FOR SOFT PASTY FOOD Russian patent published in 2021 - IPC A23G3/56 A23L5/00 B65D75/00 

FIELD: food packaging.

SUBSTANCE: invention relates to the field of food packaging and can be used in the packaging of soft pasty food products. A casing for a soft food product is proposed, made in the form of a flexible tube based on a polymeric material, and the casing material includes, as raw materials, pre-crushed to a powdery state and mixed polybutylene succinate, straw and cotton with the following ratio of mass parts 100-150:10-15:10-3 respectively, while the mixed components are heated to a temperature of 150-200°C, stirred until the raw components are completely dissolved and a homogeneous mass is obtained, then the mass is cooled to the state of its plastic deformation and a shell is formed, passing the mass through at least one profiling die to obtain a tubular products. In this case, the shell is formed with an inner diameter of 3-7 mm and a wall thickness of 0.3-0.5 mm. The resulting tubular products are cut into sections 6-12 cm long.

EFFECT: invention improves the consumer properties of the product by increasing the strength, flexibility, ease of use and environmental friendliness of the shell as a result of its rapid and complete decomposition.
