ANTISKID FLEXIBLE MATERIALS AND METHODS FOR PRODUCTION AND USE THEREOF Russian patent published in 2020 - IPC B29C59/02 B65D33/00 B32B5/16 C08J5/18 

FIELD: packaging.

SUBSTANCE: group of inventions relates to flexible anti-slip packaging materials. Proposed method comprises feeding flexible thermoplastic material, feeding first layer of discrete thermoplastic particles on hot separating surface. Discrete particles have a temperature higher than their softening temperature, providing a first layer of stickiness. Method includes contacting the carrier with a sticky first layer for attaching the first layer to the carrier, and then removing the carrier, and with it, an adhesive first layer adhered thereto from the separating surface. Temperature of the hot separating surface is higher than the temperature of melting of the carrier. Invention discloses: a method of producing an anti-slip material, a packing bag or wrapper made from the obtained material, a method of making a packing bag, a method of packaging into a packaging material obtained using the disclosed method.

EFFECT: group of inventions enables to obtain a packaging material with anti-slip properties.
