DEGRADABLE PLASTIC BOTTLE, METHOD OF ITS PRODUCTION AND METHOD OF ITS DECOMPOSITION Russian patent published in 2025 - IPC C08L67/02 C08J11/18 C08G63/08 C08G63/183 B65D1/02 

FIELD: packaging and storage; chemistry.

SUBSTANCE: invention relates to plastic articles, particularly, to degradable plastic bottle, method of its production and method of its decomposition. Bottle is made by blowing combined degradable material formed by melting and extruding mixture of resins. Mixture of resins contains the following components: 10-60 wt.pts. of polylactic acid, 20-50 wt.pts. of polybutylene-adipate-terephthalate, 0.5-20 wt.pts. of polymethylethylene carbonate, 0.5-20 wt.pts. of polyglycolic acid and 1-10 wt.pts. of calcium carbonate.

EFFECT: disclosed approach provides an increase in the crystallinity of polylactic acid by adding polymethylethylene carbonate and due to the effect of nucleation of polyglycolic acid, which increases the barrier action of the bottles with respect to pesticides and organic solvents, reducing the loss of the pesticide component and facilitating its prolonged storage.
