- the first thick portion 121B and the second thick portion 122B respectively formed in the first region R 1 and the third region R 3 is, the second region R 2 Extends beyond the widthwise end of. That is, in the second portion 120B, the first thick portion 121B and the second thick portion 122B are a part of the first region R 1 or the third region R 3 to the second region R 2, respectively. It is formed across. Thin portions 123C formed in the second region R 2 at the second portion 120B is opposed to the intermediate portion 124 of the first portion 120A.
- the first portion 120A thin portions 123A and the thin portion 123B in is formed at both end portions of the second width direction of the region R 2, the second portion 120B since the first thick section 121B and the second thick section 122B extends beyond the end of the second region R 2 in the width directions, the thin portion 123A, 123B in the thin portion of the second portion 120B Not facing each other.
- the thin-walled portion 123C formed in the second portion 120B does not face between the thin-walled portions 123A and 123B of the first portion 120A, but faces the intermediate portion 124 formed between the thin-walled portions 120A.
- the thin-walled portion 123A to the thin-walled portion 123C alternate in the width direction of the tape 120, specifically, in order from the top seal portion 112 side.
- the portion 123A, the thin-walled portion 123C, and the thin-walled portion 123B are arranged in this order without overlapping.
- the ends of the tape 120 and the bag body 110 after opening can be staggered.
- the force F for tearing the bag body 110 acts from the first surface 111A side as shown in FIG. 3A, the thin portion 123A is broken at the first portion 120A of the tape 120, and the second portion 123A is broken.
- the thin-walled portion 123C is broken at the portion 120B, and the tearing of the bag main body 110 is guided along the thin-walled portions 123A and 123C, so that the ends of the tape 120 and the bag main body 110 after opening are stepped.
- the thin portion 123C is broken at the second portion 120B of the tape 120, and the thin portion 123C is broken at the first portion 120A.
- the 123B breaks and the tearing of the bag body 110 is guided along the thin-walled portions 123B and 123C, so that the ends of the tape 120 and the bag body 110 after opening become staggered.
- the thin-walled portion formed on the side on which the force F for tearing the bag body 110 acts (the first surface 111A side in the example of FIG. 3A, the second surface 111B side in the example of FIG. 3B).
- the thin-walled portion formed on the opposite side is located on the storage space SP side, the end portion of the tape 120 after breaking tends to be misaligned. Therefore, for example, in the above example, when the thin-walled portion 123B is not formed on the first portion 120A of the tape 120, or when the force F acts from the first surface 111A side as in the example shown in FIG. 3A, the thin-walled portion 123B is formed.
- the end of the tape 120 after opening becomes staggered due to the breakage of the 123A and the thin portion 123C, but when the force F acts from the second surface 111B side as in the example shown in FIG. 3B, the force F acts. Since the thin-walled portion 123A is located closer to the top seal portion 112 than the thin-walled portion 123C, the first portion 120A is not the thin-walled portion 123A but near the intermediate portion 124 (note that if the thin-walled portion 123B is not formed, it is referred to as the intermediate portion. Is not called), and there is a possibility that the ends of the tape 120 and the bag body 110 after opening will not be staggered.
- the thin-walled portion formed on the side on which the force acts is applied. Since the thin-walled portion formed on the opposite side is located on the storage space SP side, the ends of the tape 120 and the bag body 110 after opening are more reliably staggered regardless of the direction in which the force acts. Can be.
- ribs facing the inside of the bag body may be formed at the ends of each portion (thick portion or intermediate portion) other than the thin portion.
- the thin-walled portions 123A, 123B, and 123C may be thinner than the adjacent portions, that is, the thick-walled portions 121, 122 and the intermediate portion 124, but are easily broken by the above force.
- it may be formed with a thickness of 200 ⁇ m or less.
