<P>PROBLEM TO BE SOLVED: To provide a packaging material having the function as the packaging, and the function as a kind of a container after the packaging body is unsealed. <P>SOLUTION: In a bag-shaped body in which two opposing ridges of four ridges respectively form first and second sealing parts consisting of a folding line, a sealing line, a perforation or the like; one ridge of two remaining ridges forms a third sealing part consisting of a folding line, a seal line or the like; and one remaining ridge is opened, a fourth sealing part is formed substantially orthogonal to the third sealing part by joining the opened ridges with each other while an object to be packaged is stored inside the bag, and a pair of first and second triangles with the fourth sealing part being a common bottom ridge, and a pair of third and fourth triangles with the third sealing part being a common bottom ridge are formed. Thus, a tetrahedral packaging body with the diagonals of the triangles adjacent in the peripheral direction being connected to each other is formed. A packaging material is in a ship-shape when the packaging body is unsealed along unsealing guides while the folding lines, the seal lines, the perforation lines or the like of the first and second sealing parts form the unsealing guides. <P>COPYRIGHT: (C)2008,JPO&INPIT |
