が強くなることが明らかになってきた。In order to solve this problem, the inventor of the present application provided utility model registration No. 3072321 to solve this problem. However, as the size of the plastic bag increases, it is housed in the plastic bag. It has become clear that as the capacity of the bottom seal increases, the load on the bottom seal increases and the tensile strength increases, and as a result, the tendency to damage the bottom seal increases over time.

Both side downward curved concave seals are configured such that the lower sides of both downward curved concave seals intersect the inner end of the bag body gusset, and an auxiliary bottom seal of the same type as this bottom seal is provided below the one bottom seal. Since it is formed separately and adjacent to
Even when the contents are put inside this gusseted plastic bag, the seal part is less likely to be damaged, and it has about three times the strength of the conventional parallel-sealed plastic bag. Damage at the intersection of the edge and bottom seal is extremely unlikely to occur. 3. The gusseted plastic bag according to claim 2, wherein the gusseted plastic bag body has a substantially horizontal lower seal formed below the gusseted plastic bag body, wherein the bottom seal is a two-sided slant seal, a central bottom seal, and both side lower seals. The lower curved concave seal portion on both sides intersects with the inner end of the bag body gusset, and at the lower portion of the downward curved concave seal portion, a substantially horizontal bottom seal portion is provided at an adjacent position. Since it is formed, even in this case, even if the contents are put in this gusseted plastic bag, damage from the seal part is unlikely to occur, and the strength is about three times that of the conventional parallel sealed plastic bag. Have By providing a downward curved concave seal portion at a selected position of the bottom seal portion, the occurrence of breakage at the intersection of the inner end of the gusset portion and the bottom seal is minimized. Moreover, in the plastic bag with a gusset according to claim 3, since the upper end portion of the downward curved concave seal portion has a curved shape without forming a corner portion, the damage from the upper periphery of the downward curved concave seal portion can be substantially eliminated. .
