LAMINATING ROLLER, METHOD FOR PROVIDING PACKING LAMINATE AND PACKING LAMINATE Russian patent published in 2015 - IPC B32B37/00 B32B38/04 B65D65/40 

FIELD: transport, package.

SUBSTANCE: invention relates to package for liquid or fluid food products and concerns laminating machine with laminating roller, method for providing packing laminate, packing laminate and packing. The laminating machine includes laminating roller for laminating packing laminate sheet and cooling support roller. The laminating roller contains at least one groove running along roller periphery and forming border between two peripheral areas of roller, herewith each one of peripheral areas runs continuously along the groove. Packing laminate contains core layer having at least one through hole which on its one side is covered with protective film and external layer of polymeric material. External polymeric layer and protective film laminate over each other so that polymeric layer and protective film are mutually separated along parallel, visually detectable air-filled channels formed by these two layers within area of through hole. The method consists in feeding canvas of core layer and thermoplastic material layer via contact area between cooling roller and laminating roller.

EFFECT: processing procedure optimisation and high quality of packing laminated materials production.
