FLEXIBLE PACKAGE HAVING RECLOSABLE CLIP Russian patent published in 2014 - IPC B65D33/20 

Abstract RU 2533534 C2

FIELD: packaging industry.

SUBSTANCE: flexible package comprises opposed front and rear panels joined together to form a cavity, a reclosable clip comprising opposing cohesive layers formed using a solution of the solvent from a mixture of thermoplastic elastomer and a diluting polymer, located directly on each of the front and rear panels. The cohesive layers on the front and rear panels face directly each other, so that the flexible package can be closed when the opposite cohesive layers are in contact with each other. The bond strength of cohesive layers to the panels is greater than the cohesive strength of the bond between the opposed cohesive layers.

EFFECT: invention provides multiple opening of the front and rear panels by delamination without delamination of cohesive layers from panels.
