Description

Technical Field

[0001] This utility model relates to the field of packaging tape manufacturing technology, specifically to a foldable multi-layer paper tape. Background Technology

[0002] With increasing environmental awareness, more and more countries and regions are mandating the use of paper-based packaging materials, and the use of paper-based strapping has also become a requirement for the development of environmentally friendly packaging products.

[0003] Existing multi-layer paper packing straps, where each layer is made of independent paper material glued together and then cut into strips, have the disadvantages of having many edge seams that are prone to cracking and poor bonding strength. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a folded multi-layer paper tape, which can reduce the probability of tape cracking and improve the bonding strength of each layer.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A folded multi-layer paper tape includes a tape body, the tape body including paper material and an adhesive layer, the paper material being composed of several adjacent folds in the width direction of the paper material, the several folds being stacked in the thickness direction, and an adhesive layer being provided between adjacent folds in the thickness direction.

[0007] The outer surface of the belt is embossed, and the embossing extends along the length of the belt.

[0008] Furthermore, in this application, a folded multi-layer paper tape has four folds.

[0009] Furthermore, in this application, a folded multilayer paper tape is provided, wherein the folds include a pair of first folds and a pair of second folds;

[0010] In the width direction of the paper stock, a pair of first folds correspond to one outer edge of the paper stock, and a pair of second folds are located between the pair of first folds; in the thickness direction of the strip, a pair of second folds are located on the outer side of the strip, and a pair of first folds are located between the pair of second folds.

[0011] Furthermore, in this application, a folded multi-layer paper tape is provided, wherein the paper material is kraft paper.

[0012] Furthermore, in this application, a folded multi-layer paper tape has embossing arranged at intervals along the width of the tape.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] This invention provides a foldable multi-layer paper tape. The tape body is made of folded paper material and glued together, which can reduce the number of edge glue seams and reduce the probability of cracking. After each layer is glued, the embossing is pressed out by the pressure roller, which can improve the adhesion between each layer. Attached Figure Description

[0018] Combination Figure 1 , Figure 2 The folded multilayer paper tape shown includes a tape body 1, which includes a paper material 10 and an adhesive layer 12. The paper material 10 is composed of several folds 11 that are adjacent in the width direction of the paper material 10. The several folds 11 are stacked in the thickness direction, and an adhesive layer 12 is provided between the adjacent folds 11 in the thickness direction.

[0019] The outer surface of the belt body 1 is provided with embossing 13, which extends along the length direction of the belt body 1. In this embodiment, the embossing 13 is evenly spaced in the width direction of the belt body 1.

[0020] In this application, the tape body 1 is made of paper material 10 folded and glued together, which can reduce the number of edge glue seams and reduce the probability of cracking. After each layer 11 is glued, the embossing 13 is rolled out by the pressure roller, which can improve the bonding strength between each layer 11.

[0021] Specifically, in this embodiment, the number of folds 11 is 4. Fold 11 includes a pair of first folds 111 and a pair of second folds 112; in the width direction of the paper material 10, the pair of first folds 111 respectively correspond to one outer edge of the paper material 10, and the pair of second folds 112 are between the pair of first folds 111; in the thickness direction of the belt body 1, the pair of second folds 112 are located on the outer side of the belt body 1, and the pair of first folds 111 are located between the pair of second folds 112. Based on the above structure, the belt body 1 has only one glue seam on one side, which can minimize delamination and cracking.

[0022] In this embodiment, the paper material 10 is kraft paper. Using kraft paper as the paper material in this application balances the strength of the paper strip with low cost.

[0023] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way.
