[0031] Example 1

[0032] Please refer to Figure 1 - Figure 6The present invention provides a non-slip and easy-tear packaging bag, comprising a packaging bag body 1, and an easy-tear opening 10 is provided on the heat-sealed portion 12 of at least one side edge of the packaging bag body 1 to prevent the easy-tear opening 10 from communicating with the inner cavity of the packaging bag body 1. Among them, easy-tear openings 10 are provided on the top heat-sealed portion 12 on the opposite side edges of the packaging bag body 1. By increasing the number of easy-tear openings 10, it is convenient for users to have multiple options for tearing. In addition, anti-slip portions 2 are provided on the packaging bag body 1 on the opposite sides of the outer periphery of each easy-tear opening 10 on the opposite sides. The anti-slip portions 2 are used to increase the friction between the user's hand and the packaging bag body 1. Of course, the anti-slip portion 2 is also provided on the heat-sealed portion 12 of the packaging bag body 1 to prevent the anti-slip portion 2 from communicating with the inner cavity of the packaging bag body 1.

[0033] In summary, the anti-slip and easy-tear packaging bag of the present invention is equipped with an anti-slip portion 2 at the outer gripping position of the easy-tear opening 10. When the packaging bag is torn from the easy-tear opening 10, the anti-slip portion 2 is used to increase the friction between the user's hand and the packaging bag body 1, effectively preventing the user's fingers from slipping when they are sweaty, and avoiding increased difficulty in tearing the packaging bag. This overcomes the defect of the existing packaging bag that if the user's fingers are sweaty, they are prone to slipping when tearing from the easy-tear opening 10, resulting in increased difficulty in tearing the packaging bag.

[0034] In this embodiment, the anti-slip portion 2 includes an anti-slip area 20 and an anti-slip structure. The anti-slip area 20 is disposed on the surface of the packaging bag body 1 and is located at the peripheral gripping position of the easy-tear notch 10, while the anti-slip structure is disposed within the anti-slip area 20. Therefore, it can be understood that the anti-slip effect of the anti-slip portion 2 of this embodiment comes from the anti-slip structure. The anti-slip area 20 is formed by a wireframe engraved on the surface heat-sealed portion 12 of the packaging bag body 1. The wireframe has a different color than the packaging bag body 1. For example, the wireframe is black, while the packaging bag body 1 is white. This facilitates quick identification of the position of the anti-slip portion 2 by the user.

[0035] In this embodiment, the anti-slip structure includes a plurality of anti-slip stripes 21 engraved within the anti-slip region 20 and not connected to the inner cavity of the packaging bag body 1. These anti-slip stripes 21 increase the friction between the user's fingers and the packaging bag body 1. The anti-slip stripes 21 are perpendicular to the direction in which the easy-tear opening 10 is formed, thereby preventing the anti-slip stripes 21 from interfering with the ability to tear the packaging bag through the easy-tear opening 10. For example, if the direction in which the easy-tear opening 10 is formed is the horizontal X direction, and the direction perpendicular to the horizontal X direction is the horizontal Y direction, then the anti-slip stripes 21 extend along the horizontal Y direction, with the plurality of anti-slip stripes 21 spaced apart along the horizontal X direction.

[0036] It should be noted that the anti-slip stripes 21 of this embodiment can be achieved by carving the anti-slip area 20 with a grinding knife. In other embodiments, the anti-slip stripes 21 can also be achieved by heating strips or cooling strips.

[0037] It should be noted that, in other embodiments, if the anti-slip stripes 21 are parallel to the direction of opening the above-mentioned easy-tear opening 10, then when the packaging bag is torn at the position of the easy-tear opening 10, the torn cracks may be torn along the extension direction of the anti-slip stripes 21, which is not conducive to tearing the packaging bag.

[0038] In addition, the anti-slip structure of this embodiment adopts anti-slip stripes 21. Compared with other anti-slip coating structures, the anti-slip stripes 21 of this embodiment can further increase the friction between the fingers and the packaging bag body 1.

[0039] In this embodiment, the above-mentioned anti-slip parts 2 are provided on the relative surfaces of the packaging bag body 1, that is, the above-mentioned anti-slip parts 2 are provided on the front and back sides of the packaging bag body 1, which can further increase the friction between the fingers and the packaging bag body 1 and improve the tearing effect of the packaging bag.

[0040] In this embodiment, the end of the easy-tear notch 10 facing away from the opening is connected to a linear notch 11 that is not connected to the inner cavity of the packaging bag body 1. Each linear notch 11 is perpendicular to the edge of the easy-tear notch 10. It can be seen that, without changing the original structure of the easy-tear notch 10, the linear notch 11 is equivalent to increasing the depth of the easy-tear notch 10. The linear notch 11 concentrates the force required to tear the packaging bag on a point at the end of the linear notch 11 facing away from the easy-tear notch 10, achieving the effect of saving effort when tearing the packaging bag. At the same time, the linear notch 11 acts as a linear guide, facilitating the straight-line tearing of the packaging bag, thereby effectively making the tear mark after the packaging bag is torn into a straight line, thereby effectively preventing the product from spilling out of the torn packaging bag.

[0041] In this embodiment, the above-mentioned easy-to-tear packaging bag is an environmentally friendly facial mask packaging bag. Of course, in other embodiments, the above-mentioned easy-to-tear packaging bag can also be a food packaging bag, which is not limited here.

[0042] In this embodiment, the opening center point of each tearable opening 10 falls on the extension line of each straight cut 11 extending toward each tearable opening 10. In this way, the relative two sides of the tearable opening 10 can be mirror-symmetrical about the straight cut 11, making it easier for users to tear open the packaging bag.

[0043] In this embodiment, if Figure 2 As shown, the easy-tear notch 10 is a V-shaped tear notch 101, and the connection between the V-shaped tear notch 101 and the straight line notch 11 forms a Y-shaped tearing portion. Since the V-shaped tear notch 101 can save effort when tearing the packaging bag, and the straight line notch 11 acts as a straight line guide, the Y-shaped tearing portion allows the user to tear the packaging bag along a straight line with very little force when tearing the packaging bag from the position of the V-shaped tear notch 101.

[0044] Of course, in other embodiments, such as Figure 3 and Figure 4 As shown, the easy tearing notch 10 can also be a U-shaped tearing notch 102; Figure 5 and Figure 6 As shown, the easy-tear notch 10 can also be formed by a rectangular notch 103 and a V-shaped notch 104, with the rectangular notch 103 contacting and communicating with the linear notch 11 through the V-shaped notch 104. It can be seen from this that, for those skilled in the art, by reasonably changing the structure of the easy-tear notch 10 based on the linear notch 11, it should also fall within the scope of protection of the present invention.

[0045] In this embodiment, the opening size of the easy tearing notch 10 is 2-3mm; the length of the straight cut 11 is 1-3mm. Specifically, in this embodiment, the opening size of the easy tearing notch 10 is 2mm, and the length of the straight cut 11 is 3mm. The size of the easy tearing notch 10 and the straight cut 11 is limited in this way, so that the easy tearing notch 10 is prevented from being too large without affecting the tearing effect. Of course, in other embodiments, the opening size of the easy tearing notch 10 can also be 3mm, and the length of the straight cut 11 can be 1mm, which is not limited here. Therefore, for those skilled in the art, by reasonably changing the size of the easy tearing notch 10 and the straight cut 11, it should also fall within the scope of protection of the present invention.

[0046] In this embodiment, the distance between the edge of the wire frame of the anti-slip area on both sides of the horizontal Y direction and the straight cut is set to D, and D is 4 mm. This can avoid the anti-slip area being too large, causing the anti-slip structure in the anti-slip area to affect the overall strength of the packaging bag body.

[0047] In summary, the anti-slip and easy-tear packaging bag of the present invention can not only play an anti-slip role when the packaging bag is torn from the easy-tear position, but also effectively make the tear mark after the packaging bag is torn into a straight line, thereby effectively preventing the product in the torn packaging bag from overflowing and enhancing the consumer experience.

[0048] Example 2

[0049] The difference between this embodiment and the first embodiment lies in the difference in the anti-slip structure.

[0050] like Figure 7 and Figure 8 As shown, in this embodiment, the anti-slip structure also includes a plurality of anti-slip dimples 22 engraved within the anti-slip region 20 and not connected to the inner cavity of the packaging bag body 1, thereby also providing an anti-slip effect. Specifically, the anti-slip dimples 22 may be circular, triangular, rectangular, or elliptical in shape, without limitation herein. Therefore, those skilled in the art will appreciate that reasonable modifications to the structure of the anti-slip dimples 22 will also fall within the scope of protection of the present invention.
