摘要

PROBLEM TO BE SOLVED: To provide a bag packaging body having an easily unsealable structure capable of selecting a bonding surface to be peeled by utilizing a center seal part of a heat-bonded packaging material, and a packaging machine for manufacturing the bag packaging body. SOLUTION: In the easily unsealable structure 7 provided on a pillow bag packaging body 1, a transverse seal part 5 is formed leaving a non-seal part 9 which is expanded in a projecting manner across the center seal portion 4 inwardly from an outer edge 8 of a cylindrical edge part 5a. The center seal part 4 and the non-seal part 9 facing it are picked and opened, and a transverse seal part 5b of a narrow seal area is peeled to unseal a cylindrical edge part 5a. An end part 4c of the center seal part 4 is peeled from the inner side, and side edge parts 4a and 4b are successively peeled to unseal the pillow packaging body 1.
