COMPOSITE POLYMER MATERIAL Russian patent published in 2022 - IPC C08K3/26 C08K3/34 C08K3/14 C08K7/02 

FIELD: composite polymeric materials.

SUBSTANCE: invention relates to composite polymeric materials and can be used mainly for the manufacture of an additional layer in the main polymer structure of the package in the form of a co-extrusion layer to give it additional protective properties, such as grease resistance, protection from ultraviolet radiation, and reduces the need for the use of aluminum in the package, PVC and PET. The effect is achieved in a material that contains components with the following composition, wt.%: HDPE 293-285 (PVD 15803-020, polyolefins) 34, polypropylene 7, chemically deposited chalk 23, microtalc 13, hairstanite 5, glass fiber 5, UV stabilizer 4 , antioxidant 4, rubber 3, antimicrobial additive 2.

EFFECT: increasing environmental friendliness, protective properties and mechanical and chemical strength.
