Embodiment 1

[0135] get ready figure 1 , figure 2 The packaging bag 100 of the first embodiment is shown. In this packaging bag 100 , a first slit 40 extending from the vicinity of the top surface 11 in the vertical direction (Z direction) to the vicinity of the bottom surface 12 is formed on the side surface 13 a of the main body 10 . Further, on the side of the top surface portion 11 of the side surface portion 13a, a second slit 50 extending in the lateral direction (X direction) is formed continuously from the one end 40a of the first slit 40 . In addition, on the side of the bottom surface portion 12 of the side portion 13a, it is continuous with the other end 40b of the first slit 40 and faces the second slit 50 in the vertical direction (Z direction). Extended third slot 60 . In addition, the length L1 of the first slit 40 is set to about 228mm (L1 ratio: about 100%), the length L2 of the second slit 50 is set to about 66mm (L2 ratio: 60%), and the length of the third slit 60 L...

Embodiment 2

[0137] get ready Figure 9 The packaging bag 100 of the second embodiment is shown. In this packaging bag 100, the length L1 of the first slit 40 is set to about 160 mm (L1 ratio: about 70%), the second slit 50 has a base 51, and one end of the second slit 50 is inclined relative to the base 51. Slope portion 52, in addition, the third slit 60 has a base portion 61, and the slope portion 62 in which one end of the third slit 60 is inclined relative to the base portion 61, except that the packaging bag 100 was produced in the same manner as in Example 1, and carried out evaluate. The results are shown in Table 1.

Embodiment 3

[0139] get ready Figure 10 A third embodiment of the packaging bag 100 is shown. In this packaging bag 100, the length L3 of the third slit 60 is set to be shorter than the length L2 of the second slit 50, the length L2 of the second slit 50 is set to about 66 mm (L2 ratio: 60%), and the second The packaging bag 100 was produced and evaluated in the same manner as in Example 1 except that the length L3 of the triple slit 60 was about 33 mm (L3 ratio: about 30%). The results are shown in Table 1.

Description

technical field [0001] The present invention relates to packaging bags. Background technique [0002] In recent years, daily necessities that can be used for a long time and have high storage and storage properties have become more and more popular due to changes in the actual living conditions of the residents. In sanitary thin paper such as kitchen paper towels, many long-sized products have been developed, such as increasing the winding length of the roll. For example, it takes a certain amount of time to use up one paper towel in a long size, and in many cases food is handled in the kitchen, so packaging bags that can store paper towels in a hygienic manner are required. In addition, when tearing the packaging bag of kitchen paper towels, it may not be torn neatly in many cases, so an easy-to-open packaging film is also required. [0003] For example, Japanese Unexamined Patent Publication No. 2003-104449 (Patent Document 1) discloses a package for packaging roll-shape...
