METHOD OF PRODUCING BIODEGRADABLE FILM Russian patent published in 2015 - IPC C08L5/08 

FIELD: chemistry.

SUBSTANCE: method is carried out by mixing chitosan, a glycerine plasticiser and a structure-forming agent, followed by forming the film at room temperature. The method includes dissolving 2.0 g of chitosan in 100 ml of 2% acetic acid at room temperature, adding to the obtained chitosan solution 10% aqueous gelatine solution in ratio of 3:5 and mixing. Glycerine is added to the mixture first, followed by 4% aqueous transglutaminase solution and subsequent mixing on a magnetic mixer for not more than 2 minutes at temperature of the mixture of 45-55°C.

EFFECT: invention simplifies and speeds up the process of producing a biodegradable film.
