PACKAGING BAG

To solve the problems of conventional resealable packaging bags: that at development of resealable packaging bags with a new design, requirement for securing a position for a protruding piece restricts the degree of freedom in the new design; and that capacity of the bag is reduced when the bag is resealed with a fold part folded.SOLUTION: A packaging bag 1 comprises: a main bag body 2; and at least a pair of sub-bag bodies 3,4 which is integrally connected with the main bag body 2 and into which the main bag 2 is divided in two branches. An opening 6 to be torn for opening is provided near a tip of at least one of the sub-bags, and the opening 6 can be simply resealed with the root part 8 of the sub-bag bodies that has been torn to form the opening 6 folded back toward the main bag body side of the packaging bag 1.SELECTED DRAWING: Figure 1 【課題】従来の再封可能な包装袋では、製袋時に、突出片を設ける位置を設計しなければならず、製袋の自由度が制限される。また、折り返し部分を折り返して再封した際の袋の容量が小さくなる。【解決手段】主袋体２と、主袋体２と一体に繋がっており、主袋体２から二股に分かれた少なくとも一対の副袋体３，４とを有する包装袋１において、少なくとも一つの副袋体の先端寄りに、破断して開封するための開口６が設けられており、破断して開口６を形成した副袋体の根元部８を主袋体側へ折り返すことにより、開口６を簡易的に再封できる包装袋１。【選択図】図１
