A packaging bag with a point-tear line structure

Abstract

This utility model discloses a point-tear line structure for packaging bags, including a bag body composed of a front bag surface and a back bag surface. The upper part of the front bag surface has a point-tear line for easy tearing of the bag body. The point-tear line is divided into two opposing vertical segments and a horizontal segment located above the two vertical segments. The two ends of the horizontal segment are connected to the upper ends of the corresponding vertical segments by an arc segment. Neither of the two arc segments penetrates the front bag surface. In this way, the tear line guides the user to tear the bag body along a preset trajectory, avoiding skewed or deviated tear lines and significantly reducing the difficulty of tearing the bag. Secondly, the arc segments that do not penetrate the front bag surface improve the structural strength and can prevent the tear line from breaking prematurely due to external forces during production and packaging.

Description

Technical Field

[0001] This utility model relates to the field of product packaging, specifically to a tear-off line structure for packaging bags. Background Technology

[0002] In the packaging industry, film packaging bags are widely used for packaging various items due to their lightweight, low cost, and good sealing properties. Common film packaging bags typically consist of a bag body, which is composed of a front bag face and a back bag face. The top, left, and right edges of the front and back bag faces are sealed together to enclose the receiving cavity, leaving only the bottom opening as a passage for the items to be placed inside.

[0003] During the packaging process, workers place the items to be packaged into the receiving cavity through the opening at the bottom of the bag, and then heat-seal the opening to complete the packaging. To facilitate user access to the contents, a U-shaped tear line is provided on the front of the bag. Users simply tear along this tear line to open the bag and retrieve the contents.

[0004] However, in the actual packaging process, when items are placed into the bag's containment cavity, a certain impact is exerted on the bag's interior. Because the tear line is U-shaped, its curved corners are relatively weak, making them prone to tearing under this impact. This premature damage, not caused by intentional user action, not only ruins the original appearance of the packaging bag, diminishing the product's aesthetic appeal, but also provides a poor user experience, negatively impacting the user's overall evaluation of the product. Utility Model Content

[0005] Based on this, and in response to the aforementioned technical problems, this utility model provides a point-tear line structure for packaging bags.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A perforated tear line structure for a packaging bag includes a bag body composed of a front bag face and a back bag face. The upper part of the front bag face has a perforated tear line for easy tearing of the bag body. The perforated tear line is divided into two opposing vertical segments and a horizontal segment located above and between the two vertical segments. The two ends of the horizontal segment are connected to the upper ends of the corresponding vertical segments by an arc segment. Neither of the two arc segments penetrates the front bag face.

[0008] By employing the above technical solution, the tear line guides the user to tear the bag along a preset trajectory, preventing the tear from being crooked or deviating, and significantly reducing the difficulty of tearing the bag. Simultaneously, the transition between the horizontal and vertical sections via a rounded section is not only more aesthetically pleasing than a right-angle transition, but also better suits the hand's force application habits, reducing the feeling of jamming during tearing and making the bag opening process smoother and less strenuous. Furthermore, the rounded section that does not penetrate the entire bag surface enhances structural strength, preventing the tear line from prematurely breaking due to external forces during production and packaging.

[0009] In a specific embodiment of this utility model: the vertical segment is a straight line, and the horizontal segment is an arc.

[0010] In a specific embodiment of this utility model: both the front bag surface and the back bag surface are made of PE or PVC.

[0011] In summary, in this utility model, the two corner arc segments of the point-break tear line do not penetrate the front of the bag, which improves the structural strength and effectively prevents the tear line from breaking prematurely due to external forces during production and packaging.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 and Figure 2As shown, this utility model discloses a tear-off line structure for a packaging bag, comprising a bag body consisting of a front bag face 10 and a back bag face 11. The upper, left, and right edges of the front bag face 10 and the back bag face 11 are sealed together to form a receiving cavity. The opening at the lower end of the bag body serves as a channel for inserting items. During packaging, the items to be packaged are placed into the receiving cavity through the opening at the lower end of the bag body. The opening is then sealed. In this embodiment, the sealing connection can be achieved using heat fusion welding.

[0019] In this embodiment, both the front pocket 10 and the back pocket 11 are made of PE or PVC material.

[0020] To facilitate users in tearing open the bag, a tear line 13 is provided on the upper part of the front of the bag 10.

[0021] In this embodiment, the tear line 13 has a U-shaped structure, consisting of two opposing vertical segments 14 and a horizontal segment 15 located above and between the two vertical segments 14. Both ends of the horizontal segment 15 are connected to the upper ends of their respective vertical segments 14 by an arc segment 16. Here, the tear line 13 guides the user to tear the bag along a preset trajectory, preventing the tear from being crooked or deviating, significantly reducing the difficulty of tearing the bag. Simultaneously, the horizontal segment 15 and the vertical segment 14 are connected by the arc segment 16. Compared to a right-angle transition, the arc transition is not only more aesthetically pleasing but also better suits the hand's force application habits, reducing the feeling of sticking during tearing and making the bag opening process smoother and less strenuous.

[0022] In this embodiment, the vertical segment 14 is a straight line, and the horizontal segment 15 is an arc.

[0023] In this embodiment, both the vertical segment 14 and the horizontal segment 15 penetrate the front of the bag 10. Neither of the two arc segments 16 penetrates the front of the bag 10. With this structure, the arc segments that do not penetrate the front of the bag increase the structural strength and can prevent the tear lines from breaking prematurely due to external forces during production and packaging.

[0024] The aforementioned point-tear line 13 can be used as follows Figure 3 and Figure 4 The tool 1 in the process achieves this. The tips of the cutting teeth 2 on the tool 1 corresponding to the positions of the arc segments can be ground to be slightly lower than the tips of the cutting teeth in other positions. This allows the point-break tear lines processed by the tool 1 to maintain the effect of penetrating the front of the bag in the horizontal and vertical segments, while the depth of the scratches in the arc segments will be shallower and unable to penetrate the front of the bag, thereby improving the tear strength of the arc segment.

[0025] In summary, in this utility model, the two corner arc segments of the point-break tear line do not penetrate the front of the bag, which improves the structural strength and effectively prevents the tear line from breaking prematurely due to external forces during production and packaging.

[0026] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
