Description

Technical Field

[0001] This utility model relates to the field of kraft paper tape technology, specifically to a kraft paper tape structure with high tensile strength. Background Technology

[0002] Kraft paper tape is a packaging material consisting of a layer of kraft paper and an adhesive. Kraft paper is made from pulp, pigments, and inks and has a textured surface. The adhesive is made from components such as resin, solvent, pigments, and thickeners. Kraft paper tape is constructed by coating layers of kraft paper and adhesive together to form a tape.

[0003] However, current kraft paper tape has a simple structure and lacks tensile strength. Kraft paper tape is often used for sealing boxes and bundling items (such as cardboard boxes, building materials, furniture, etc.). If the tensile strength is insufficient, it is easily torn during handling, stacking or transportation, resulting in loose packaging and scattered goods. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a kraft paper tape structure with high tensile strength, which increases tensile strength by reinforcing strips and reinforcing filaments, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a kraft paper tape structure with high tensile strength, comprising a kraft paper layer and an adhesive layer, wherein the kraft paper layers are arranged in parallel, one above the other, and the middle of the kraft paper layer is bonded and fixed to the adhesive layer. The two sides of the kraft paper layer are bent to form L-shaped portions, and installation channels are formed between the L-shaped portions and the adhesive layer. Reinforcing strips are bonded and fixed in the installation channels, and multiple reinforcing wires are longitudinally installed between the reinforcing strips.

[0006] As a preferred technical solution, the middle arch of the kraft paper layer is provided with multiple mounting parts, and mounting holes are formed between the mounting parts and the adhesive layer. The reinforcing wires are all installed in the mounting holes and are fixed by bonding and adhering the kraft paper layer and the adhesive layer. Both ends of the reinforcing wires are inserted into the reinforcing strip and are bonded and fixed to the reinforcing strip.

[0007] As a preferred technical solution, the kraft paper layer is made of long-fiber pure wood pulp or mixed bamboo pulp.

[0008] As a preferred technical solution, the reinforcing strip is made of foam substrate.

[0009] As a preferred technical solution, all reinforcing wires are transparent threads.

[0010] As a preferred technical solution, the outer surfaces of the L-shaped plate, reinforcing strip, and adhesive layer are flush.

[0011] As a preferred technical solution, the L-shaped part is integrally formed with the kraft paper layer, and the curved part of the L-shaped part is thickened.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure, the kraft paper layer made of reinforcing strips and long fibers increases the transverse tensile strength, and the reinforcing filaments increase the longitudinal tensile strength. Moreover, the reinforcing strips made of foam and the longitudinally arranged reinforcing filaments do not affect the tearing of the kraft paper layer or the efficiency of adhesion.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a kraft paper tape structure with high tensile strength, comprising a kraft paper layer 1 and an adhesive layer 2. The kraft paper layers 1 are arranged in parallel, one above the other, and the middle of the kraft paper layer 1 is bonded and fixed to the adhesive layer 2. The two sides of the kraft paper layer 1 are bent to form L-shaped portions 3. An installation channel is formed between the L-shaped portions 3 and the adhesive layer 2. Reinforcing strips 4 are bonded and fixed in the installation channels. Multiple reinforcing wires 6 are longitudinally installed between the reinforcing strips 4.

[0022] In this embodiment, the middle arch of the kraft paper layer 1 is provided with multiple mounting parts 5. Mounting holes are formed between the mounting parts 5 and the adhesive layer 2. The reinforcing wires 6 are all installed in the mounting holes and are fixed by the kraft paper layer 1 and the adhesive layer 2. Both ends of the reinforcing wires 6 are inserted into the reinforcing strips 4 and are fixed by the reinforcing strips 4.

[0023] In this embodiment, the kraft paper layer 1 is made of long-fiber pure wood pulp or mixed bamboo pulp. The longer the fiber, the better the tensile strength.

[0024] In this embodiment, the reinforcing strip 4 is made of foam substrate. The foam material is soft but has a certain elasticity, which can increase the lateral tensile strength of the kraft paper tape. However, it can be torn during use without affecting the normal use of the kraft paper tape.

[0025] In this embodiment, the reinforcing filaments 6 are all transparent threads. The transparent threads can provide longitudinal strength to the kraft paper tape, greatly increasing the longitudinal tensile strength.

[0026] In this embodiment, the outer surfaces of the L-shaped plate, reinforcing strip 4, and adhesive layer 2 are flush, which increases the smoothness of the edges.

[0027] In this embodiment, the L-shaped part 3 is integrally formed with the kraft paper layer 1, and the bending part of the L-shaped part 3 is thickened to avoid breakage at the bending point and ensure its service life.

[0028] The kraft paper layer, made of reinforcing strips and long fibers, increases the transverse tensile strength, while the reinforcing filaments increase the longitudinal tensile strength. In use, the kraft paper layer can be torn from the middle of the reinforcing filaments, and the reinforcing strips can be torn directly, thus avoiding affecting the normal use of the kraft paper tape.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
