PROBLEM TO BE SOLVED: To provide a packaging bag which can be more surely cut to open along a half-cut line.SOLUTION: A packaging bag 10 comprises: sealed parts 11 made by adhering peripheral edges of laminated films 12 and 13; a storage part 18 formed between the laminated films 12 and 13; and unsealing means 20 for unsealing the packaging bag 10. The unsealing means 20 has: a first half-cut line 21 which crosses linearly a space between easily unsealed/processed parts 24 of the laminated film 13; second and third half-cut lines 22 and 23 which are formed to bulge toward a lower end part 16 and an upper end part 17 respectively between the easily unsealed/processed parts 24 of the laminated film 12; and a pair of auxiliary half-cut lines 26 which sandwich parts of the second and third lines. An endpoint of the second half-cut line 22 and an endpoint of the third half-cut line 23 are positioned between the pair of auxiliary half-cut lines 26.SELECTED DRAWING: Figure 1 |
