To provide a packaging body which is easily unsealed and suitable for packaging vegetables by using a sealing part necessary for manufacturing a bag body with one end thereof being opened as an unsealing guide for tearing.

A packaging body 6 uses a bag body comprising first and second sealing parts 2 and 3 with two opposing ridges of four ridges consisting of seal lines by thermo-compression bonding, and a third sealing part 4 with one ridge out of the two remaining ridges consisting of a folding line, while the remaining ridge is opened. A fourth sealing part 5 is formed by joining the opened ridges with each other at an angle substantially orthogonal to the third sealing part 4 while an object to be packaged is stored inside the bag body. A pair of first and second triangles with the fourth sealing part 5 as a common bottom ridge, and a pair of third and fourth triangles with the third sealing part 4 as a common bottom ridge are formed, and the tetrahedral packaging body 6 with diagonal ridges of the triangles adjacent to each other in the peripheral direction connected to each other is formed. Vegetables such as lettuce and spinach are sealed with air in the packaging body 6 as the object to be packaged. The seal lines by thermo-compression bonding of the first and second sealing parts 2 and 3 located on the perpendiculars of the first and second triangles are formed to be unsealing guides for tearing.
