Description

Technical Field

[0001] The utility model relates to the field of tape structures, in particular to a degradable self-adhesive water-based kraft paper tape. Background Art

[0002] With the rise of online shopping and the express delivery industry, a large number of express packages use tapes made of OPP materials. The OPP tape is based on a polypropylene film substrate and is basically non-recyclable and non-degradable, which is not conducive to environmental protection. Content of the Utility Model

[0003] In view of the deficiencies in the above-mentioned background art, the utility model provides a degradable self-adhesive water-based kraft paper tape.

[0004] The utility model adopts the following technical scheme:

[0005] A degradable self-adhesive water-based kraft paper tape, characterized in that the tape comprises:

[0006] A base cloth layer, and the base cloth layer is made of virgin paper;

[0007] A reinforcing layer, and the reinforcing layer is composed of yarns distributed in a staggered manner;

[0008] An adhesive layer, and the adhesive layer is a water-based glue.

[0009] In a possible implementation manner, the yarns of the reinforcing layer include first yarns arranged on both sides of the base cloth layer and second yarns arranged in the middle of the base cloth layer. The first yarns extend linearly along the length direction of the base cloth layer, and the second yarns extend in a wavy line along the length direction of the base cloth layer, and the wave crests and wave troughs of the second yarns are respectively superimposed and staggered with the two first yarns.

[0010] From the above description of the structure of the utility model, compared with the prior art, the utility model has the following advantages: The utility model uses virgin paper as the base cloth layer and water-based glue as the adhesive layer. Compared with the OPP material tape, it has good tensile strength and adhesiveness, can better ensure the safety of the items in the package, avoid the package from falling apart or being damaged during transportation, and the virgin paper and water-based glue are easier to degrade and will not leave pollutants in the natural environment. Therefore, the utility model is more environmentally friendly. Description of the Drawings

[0013] Figure 3It is a schematic diagram of one of the ways in which yarns are distributed in the base fabric layer in the prior art. Detailed implementation mode

[0014] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0015] Hereinafter, terms such as "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

[0016] In addition, in the present application, orientation terms such as "upper" and "lower" are defined relative to the orientation in which the components in the drawings are schematically placed. It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and they may change accordingly with the change of the orientation in which the components in the drawings are placed.

[0017] What the present utility model discloses is a degradable self-adhesive water-based kraft paper tape. As shown in the attached Figure 1 , the tape includes a base fabric layer 1, a reinforcing layer 2 and a paste layer 3 arranged in this way. Among them, the base fabric layer 1 is made of raw kraft paper, making the present utility model have strong toughness and tensile strength. The paste layer 3 is a water-based glue, preferably starch glue, making the present utility model relatively easy to degrade and thus more environmentally friendly.

[0018] Referring to the attached Figure 2 again, the reinforcing layer 2 is composed of yarns distributed in a staggered manner. Specifically, the yarns of the reinforcing layer 2 include first yarns 21 arranged on both sides of the base fabric layer 1 and second yarns 22 arranged in the middle of the base fabric layer 1. Among them, the first yarns 21 extend linearly along the length direction of the base fabric layer 1, and the second yarns 22 extend in a wavy line along the length direction of the base fabric layer 1, and the peak and valley positions of the second yarns 22 are respectively superimposed and staggered with the two first yarns 21. In this structure, both the first yarns 21 and the second yarns 22 can improve the tensile strength of the tape along its length direction, and the wavy setting of the second yarns 22 is beneficial to improving its tensile strength in the width direction. Further, the superimposed and staggered arrangement of the second yarns 22 and the first yarns 21 can improve the overall structural strength of the reinforcing layer, making it not easy to deform or displace. At the same time, when it is necessary to tear the tape transversely, only the second yarns 22 and the two first yarns 21 need to be torn. Compared with the structure in which multiple yarns are distributed as shown in the attached Figure 3 , while ensuring the tensile strength, it is also easier to tear, which is beneficial to improving the convenience of use.

[0019] In addition, since the reinforcing layer 2 is composed of yarns and has a height difference from the base fabric layer 1, an antifoaming agent can be added to the water-based glue to avoid the formation of air bubble holes between the yarns and the base fabric layer 1 during the roll pressing and laminating process, which helps to improve the adhesiveness of the adhesive layer 3 to the base fabric layer 1 and the reinforcing layer 2 respectively.

[0020] In summary, the present utility model uses virgin paper as the base fabric layer 1 and water-based glue as the adhesive layer 3. Compared with tapes made of materials such as OPP, it has good tensile strength and adhesiveness, can better ensure the safety of the items in the package, and avoid the package from scattering or being damaged during transportation. Moreover, virgin paper and water-based glue are more easily degradable and will not leave pollutants in the natural environment. Therefore, the present utility model is also more environmentally friendly.

[0021] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
