PROBLEM TO BE SOLVED: To provide a packaging bag in which cut-off unsealing lines can proceed along unsealing scheduled lines and the unsealing lines after the bag is unsealed are formed at different positions on front and rear films.SOLUTION: A packaging bag A comprises a front film 1 and a rear film 2. In the front film 1 and the rear film 2 are provided a left side seal part 3 at a left edge side of which the front film 1 and the rear film 2 are sealed and a right side seal part 4 at a right edge side of which the front film 1 and the rear film 2 are sealed. In the rear film 2 is formed a rear half cut line 8 linearly shaped. In the front film 1 is formed a plurality of front half cut lines 7 shaped linearly. The plurality of front half cut lines 7 and the rear half cut line 8 are overlapped with each other so that the rear half cut line 8 crosses the plurality of front half cut lines 7.SELECTED DRAWING: Figure 1 |
