<p>PROBLEM TO BE SOLVED: To provide a packing bag whose respective cut areas can be easily picked by fingers, without aligning the cut area of one side sheet and the cut area of the other side sheet, when tearing off a pair of opposed sheets.SOLUTION: When adding tearing-off directional force by picking mutually opposed parts by sandwiching an overlapping part 21 of a sealing part 9, a packing sheet 5 is torn off with a bottom apex part 13d of one side notch 13 as a starting point, and a packing sheet 7 is torn off with a bottom apex part 17c of the other side notch 17 as a starting point simultaneously with this. Thus, the cut area 29 is formed in the packing sheet 5, and the cut area 31 is also formed in the packing sheet 7, and an opening port 33 is formed in a bag body 3. Since the bottom apex parts 13d and 17d are deviatively provided in the vertical direction, a step difference is caused between the cut area 29 of the packing sheet 5 and the cut area 31 of the packing sheet 7. Thus, the respective cut areas 29 and 31 can be easily picked, and the opening port 33 can be easily opened.</p> |
