PROBLEM TO BE SOLVED: To provide a tetrahedron packaging body which can be kept and sealed easily in an original tetrahedron shape after opening the packaging body, taking out a part of a content, and resealing it, can prevent collapse of stored food or the like, and can keep its freshness, and provide a bag body used for the same.SOLUTION: A bag body comprises a left side face seam or folding part, a right side face seam or folding part, and an upper end side face seam or upper side face folding part. A lower side face is open, a fastener is provided on an inner face separated by a predetermined distance from the upper end side face seam or upper side face folding part, and a packaged object is stored from the lower side face. In a tetrahedron packaging body formed from the bag body, the lower side face is sealed by a wider side face seam in a direction orthogonal to the fastener while the packaged object is stored from the open lower side face of the bag body.SELECTED DRAWING: Figure 8 |
