PROBLEM TO BE SOLVED: To provide a packaging bag in which a stored object extraction passage can be bent without holding a portion of an extraction port with fingers directly, the bent state of the stored object extraction passage can be maintained, and the bag can be resealed repeatedly with simple operation without being contaminated.SOLUTION: An extraction port is provided at an upper part of a packaging bag 1. A ceiling engaging part 21 is formed in a part of a ceiling seal part 8 near the extraction port. A side part engaging part 31 capable of engaging with the ceiling engaging part 21 is formed in either one of side seal parts 13. When the ceiling engaging part 21 is folded toward the side part engaging part 31, the extraction port is also folded following the ceiling engaging part. The folded state can be maintained by engaging the ceiling engaging part 21 and the side part engaging part 31.SELECTED DRAWING: Figure 1 |
