BIODEGRADABLE POLYMER COMPOSITION FROM SECONDARY STARCH-CONTAINING RAW MATERIAL Russian patent published in 2018 - IPC C08L3/04 C08L5/06 C08L1/10 C08J5/18 B65D65/46 B65D81/34

Abstract RU 2651034 C1

FIELD: chemistry.

SUBSTANCE: invention relates to polymer compositions for making articles capable of undergoing biodegradation under natural conditions, in particular a food packaging film. Composition contains components at the following ratio, wt%: mixture of potato-starch pulp and sorbitol plasticiser (10) or a mixture of potato cellular fluid and dibutyl sebacate plasticiser (5); pectin (10), carboxymethyl cellulose (10); sodium alginate (10); water – the balance up to 100.

EFFECT: higher strength and degree of decomposition of the polymer compositions.
