FIELD: molded biodegradable products.
SUBSTANCE: invention can be used in the manufacture of molded biodegradable products. The method for obtaining a polysaccharide composite material with a bonding ability includes mixing, heating and ultrasonic treatment of the mixture components. The mixture includes potato starch, sodium alginate, glycerin and distilled water. Ultrasonic treatment is carried out for 5 minutes when heated to 60-65°C, then the mixture is cooled to a temperature of 40°C and a film is formed. After drying, the film is crushed to a particle size of 150-400 mcm.
EFFECT: improving the flowability and bonding ability of the powder of the polysaccharide composite material.
