[0022] The following will be combined with the attached embodiment of the utility model Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] like Figures 1 to 3 As shown, the utility model discloses a sealed easy-to-open packaging bag, comprising a bag body 1, wherein the bag body 1 comprises a front side 11 and a back side 12.

[0025] The bag body 1 is provided with a tear line group, which includes a straight line segment 21 and a parabola segment 22. In this structure, the front side 11 and the back side 12 of the bag body 1 are both laterally extended with a straight line segment 21. At the same time, the parabola segment 22 is arranged on two sides and is respectively located on the left and right sides of the bag body 1. The ends of the parabola segment 22 are respectively used to connect the straight line segments 21 on the front side 11 and the back side 12 of the bag body 1.

[0026] There are two tear line groups on the bag body 1, which are respectively close to the upper and lower ends of the bag body 1. At the same time, the parabola segment 22 in each tear line group is set as follows: the middle part of the parabola segment 22 is arched toward the end of the bag body 1 where it is located.

[0027] Two second tear lines 31 extend longitudinally from the back surface 12 of the bag body 1 , and each second tear line 31 extends from a straight line segment 21 of one tear line group to a straight line segment 21 of another tear line group.

[0028] Finally, two adhesive layers 41 are arranged inside the bag body 1 , and the adhesive layers 41 are arranged symmetrically on the back side 12 of the bag body 1 .

[0029] The working principle of the above structure is: because the shape of the tear line group on the left and right sides of the bag body 1 is parabolic, when a person's hand moves on that side, this part of the tear line can be easily broken. After the tear line where the parabola segment 22 is located is broken, it is only necessary to pinch the seal 5 of the bag body 1 and pull it, so that the seal 5 of the bag body 1 can be separated from the bag body 1 along the tear line group.

[0030] If the bag body 1 is disassembled along the two tear line groups and the second tear line 31, the area with the pattern theme printed in the middle of the bag body 1 can be unfolded. This design is mainly for the convenience of some card lovers to collect packaging bags. Compared with the traditional cutting with scissors, which is easy to cut crooked, the design of the tear line group and the second tear line 31 can make it convenient for card lovers to obtain a packaging bag souvenir with clear and symmetrical edges. At the same time, the adhesive layer 41 can also be used to stick the packaging bag souvenir to an album or book.

[0031] The position of the second tear line is more specifically: if a heat strip is longitudinally arranged in the middle of the back side 12 of the bag body 1 during processing, the second tear line 31 is respectively located on both sides of the heat strip.

[0032] In addition, the position of the parabola segment 22 and the setting of the arch direction can make the parabola segment 22 close to the seal 5 of the bag body 1 where the tearing hole is easily formed in the bag body 1. When people do not see the tear line group but directly tear the bag using the traditional method, the packaging bag will pass through the parabola segment 22 during the tearing process, and people will be able to find the tear line group at this time.

[0033] Note: Figure 3 The dotted lines on the middle packaging bag do not represent the actual structure, but are only used to facilitate the distinction between the front side 11 and the back side 12 of the bag body 1. Figure 3 The front side 11 and the back side 12 of the middle bag body 1 are both facing backwards.

[0034] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
