DETAILED DESCRIPTION

[0020] ​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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] like Figures 1-5 As shown, this utility model provides a PET packing strap that is easy to cut, including a packing strap body 1. The packing strap body 1 has a breakage mark 2, which divides the packing strap body 1 into segment A 3 and segment B 4. The breakage mark 2 includes a first horizontal rib 5 and a second horizontal rib 6. The first horizontal rib 5 is fixedly connected to the second horizontal rib 6 by a first connecting rib 7. The first horizontal rib 5 is fixedly connected to segment A 3 by a second connecting rib 8. The second horizontal rib 6 is fixedly connected to segment B 4 by a third connecting rib 9. The first horizontal rib 5 has a first indentation 10, and the second horizontal rib 6 has a second indentation 11. The distance between segment A 3 and the first horizontal rib 5, the distance between the first horizontal rib 5 and the second horizontal rib 6, and the distance between the second horizontal rib 6 and segment B 4 are all 1mm. Reinforcing layers 12 are fixedly connected to both the upper and lower sides of the packing strap body 1. An indicator line 13 is provided on the outer side of the reinforcing layer 12 at the breakage mark 2. The packing strap body 1 has breakage marks 2 at 30cm intervals.

[0023] Through the above technical solution, the packing strap body 1 of this utility model is provided with a breakage mark 2. The breakage mark 2 divides the packing strap body 1 into section A 3 and section B 4. The breakage mark 2 includes a first horizontal rib 5 and a second horizontal rib 6. The first horizontal rib 5 is fixedly connected to the second horizontal rib 6 through a first connecting rib 7. The first horizontal rib 5 is fixedly connected to section A 3 through a second connecting rib 8. The second horizontal rib 6 is fixedly connected to section B 4 through a third connecting rib 9. When the packing strap body 1 is cut, it is torn open from the breakage mark 2. Under the action of tension, the first connecting rib 7, the second connecting rib 8, or the third connecting rib 9 breaks, causing the packing strap body 1 to break.

[0024] The easy-break mark 2 of this utility model includes a first transverse rib 5 and a second transverse rib 6, which are then connected by multiple connecting ribs to improve the tensile strength of the packing strap body 1.

[0025] Example 2:

[0026] like Figures 1-5As shown, the packing strap body 1 of this utility model is provided with a breakage mark 2. The breakage mark 2 divides the packing strap body 1 into segment A 3 and segment B 4. The structure of the breakage mark 2 includes a first horizontal rib 5 and a second horizontal rib 6, which are arranged in parallel and fixedly connected by a first connecting rib 7. The first horizontal rib 5 is fixedly connected to segment A 3 by a second connecting rib 8, and the second horizontal rib 6 is fixedly connected to segment B 4 by a third connecting rib 9. This structural design allows the packing strap to maintain sufficient strength during normal use, while also allowing for easy breakage from the breakage mark 2 when cutting is required.

[0027] The first horizontal rib 5 and the second horizontal rib 6 are elongated strips, running side by side across the width of the packing strap. The first connecting rib 7 is located between the two horizontal ribs, serving to connect and fix them; multiple first connecting ribs are provided. The second connecting rib 8 connects the first horizontal rib 5 and section A 3, and the third connecting rib 9 connects the second horizontal rib 6 and section B 4. These two connecting ribs ensure the connection strength between the fragility 2 and the packing strap body 1.

[0028] During use, when it is necessary to cut the packing strap, the user can apply tensile or bending force to the breakage mark 2. Due to the special structure of the breakage mark 2, the stress will concentrate at the connecting ribs. The first connecting rib 7, the second connecting rib 8, or the third connecting rib 9 will break due to stress concentration. In this way, the packing strap will break at the predetermined position without the need for additional tools.

[0029] Example 3:

[0030] like Figures 1-5 As shown, a first indentation 10 is provided on the first transverse rib 5, and a second indentation 11 is provided on the second transverse rib 6. The addition of these two indentations further enhances the cutting effect of the breakage mark 2. The first indentation 10 is located on the surface of the first transverse rib 5 and is perpendicular to the length direction of the first transverse rib 5. Similarly, the second indentation 11 is located on the surface of the second transverse rib 6 and is also perpendicular to the length direction of the second transverse rib 6. When an external force is applied to the packing strap, the stress will preferentially concentrate at the indentation. This stress concentration effect makes the cutting process easier to initiate and carry out. Specifically, when the user applies tensile or bending force to the breakage mark 2, the crack will preferentially start from the indentation and then rapidly expand along a preset path, eventually causing the packing strap to break neatly at the breakage mark 2. The design of the indentation enhances the cutting effect without significantly affecting the tensile strength of the breakage mark 2.

[0031] Example 4:

[0032] like Figures 1-5As shown, the upper and lower sides of the packing belt body 1 are fixedly connected with the reinforcing layer 12. The reinforcing layer 12 is made of the same PET material as the packing belt body 1, and is firmly connected with the packing belt body 1 through a hot melting or bonding process. The thickness of the reinforcing layer 12 is slightly thinner than that of the packing belt body 1, but is sufficient to significantly improve the overall strength and toughness of the packing belt. The width of the reinforcing layer 12 is the same as that of the packing belt body 1, ensuring that the entire packing belt is provided with comprehensive reinforcing effect. On the outer side of the reinforcing layer 12, a clear indication line 13 is arranged at the position of the breakage mark 2. The indication line 13 adopts a color that is in sharp contrast with the color of the packing belt body 1, for example, when the packing belt body 1 is white, the indication line 13 can be selected to be red or black. The indication line 13 is directly marked on the surface of the reinforcing layer 12 through a printing or embossing process, ensuring that it will not wear off during long-term use. The width of the indication line 13 is moderate, which is easy to identify and does not affect the appearance of the packing belt. The setting position of the indication line 13 accurately corresponds to the breakage mark 2, and on both sides of the breakage mark 2 of the packing belt body 1, the outer surface of the reinforcing layer 12 has a corresponding indication line 13.

[0033] The existence of the reinforcing layer 12 not only enhances the strength of the packing belt, but also provides a good carrier for the indication line 13. The clear marking of the indication line 13 greatly improves the efficiency and accuracy of workers positioning the breakage mark 2. In actual use, workers can quickly identify the indication line 13 to find the position of the breakage mark 2, thereby realizing rapid and accurate cutting operation.
