METHOD FOR MANUFACTURING POUCH CONTAINER PACKAGING MATERIAL, DEVICE FOR MANUFACTURING POUCH CONTAINER PACKAGING MATERIAL, AND INTERMEDIATE PRODUCT OF POUCH CONTAINER PACKAGING MATERIAL

Document Type and Number:

WIPO Patent Application WO/2017/056558

Kind Code:

A1

Abstract:

To provide a method for manufacturing a pouch container packaging material, whereby it is possible to more efficiently manufacture a pouch container packaging material which can be independent and which is used in a pouch container whereby discomfort during gripping can be suppressed, a device for manufacturing a pouch container packaging material, and an intermediate product of a pouch container packaging material. This method for manufacturing a pouch container packaging material is provided with: a first step for forming a cylindrical film 1 having a vertical seal part 20; a second step for forming a first bottom seal part 21; a third step having a process for forming a pair of main film parts 10 by discharging a portion of gas in the cylindrical film 1, a process for forming a transition part 12 expanded by residual gas, and a process for causing both ends of the first bottom seal part 21 to approach each other while discharging the gas in the transition part 12 and thereby folding the first bottom seal part 21 and the transition part 12 into a flat shape along the pair of main film parts 10 so divide the first bottom seal part 21 and the transition part 12 in two; a fourth step for forming a pair of second bottom seal parts 22; and a fifth step for cutting the cylindrical film 1 so as to vertically cut the pair of second bottom seal parts 22.
