Zusammenfassung:It is an object of the present invention to provide a packaging bag that is able to minimize the destruction of the packaging bag from a connection part between a first linear welded part and a second linear welded part. The packaging bag includes a first reinforcement part and a second reinforcement part. In the packaging bag, near the first linear welded part, one of a pair of sheet-shaped walls has a surface opposite to a surface of one of a pair of opposite parts, which opposite surfaces are bonded to each other; the pair of opposite parts have surfaces opposite to each other, which opposite surfaces are bonded to each other; and the other of the pair of sheet-shaped walls has a surface opposite to a surface of the other of the pair of opposite parts, which opposite surfaces are bonded to each other. Thereby, the first reinforcement part is formed. The pair of sheet-shaped walls have surfaces opposite to each other and these opposite surfaces are bonded to each other near the second linear welded part. Th
