Title:
PACKAGING BAG
Document Type and Number:
WIPO Patent Application WO/2020/256423
Kind Code:
A1
Abstract:
A packaging bag according to the present invention is configured such that the left and right ends of a first sheet and a second sheet are bonded in a line shape by thermal bonding in a state in which the first sheet and the second sheet are overlapped, the upper ends of the first sheet and the second sheet are not attached to form an inlet, and the lower ends of the first sheet and the second sheet are attached to form an enclosure. The packaging bag has an opening penetrating the bonded portion bonded in the line shape at each of the left and right ends of the first sheet and the second sheet, such that the force for opening the inlet is dispersed through the openings to the first sheet and the second sheet, rather than to the bonded portion, thereby preventing the bonded portion from separating.
