METHOD TO MANUFACTURE FLEXIBLE PACKAGING LAMINATED MATERIAL Russian patent published in 2012 - IPC B31B19/14 B31B23/00 B65D75/58 

FIELD: construction.

SUBSTANCE: method to manufacture a flexible packaging laminated material, including supply of the first structure, containing at least one layer, onto the first cutting station, where an external cutting line is formed, application of a contact glue onto one surface of the first structure and application of a permanent laminating glue onto one surface of the first structure so that the permanent glue does not cover the contact glue. Afterwards adhesive connection of the first structure with the second structure is carried out with the help of the permanent glue to form the laminated material. The second structure includes at least one layer of a flexible material. Then the laminated material is sent to the second cutting station, on which the inner cutting line is formed on the second structure, in which the external cutting line is used for the external opening part of the first structure, which is made as capable of separation from the first structure along the external cutting line. At the same time the inner cutting line is used for the inner opening part of the second structure, which is connected with the outer opening part with the permanent glue and is arranged as capable of separation from the second structure along the inner cutting line.

EFFECT: invention provides for creation of an improved process to manufacture a flexible packaging laminated material designed for manufacturing packages.
