PROBLEM TO BE SOLVED: To provide a manufacturing method of a lateral gusset bag with a suspension header, capable of inexpensively molding a blister pack-like packing bag with the header, by using a thin film material.SOLUTION: A storage part forming process 100 forms a lateral gusset 11 by folding in along longitudinal both side edges of a belt-like film 1. A storage part 10 is formed by cutting the belt-like film 1 in the predetermined length. A positioning process 200 places and temporarily fastens the storage part 10 on a roll-like film 2. A header forming process 300 provides the suspension header 21 on the upper end part side of the roll-like film. A longitudinal seal process 400 welds the storage part 10 to the roll-like film 2. A cut process 500 forms the lateral gusset bag with the header 21 by cutting the roll-like film 2. |
