Abstract
Description
Technical Field
[0001] This utility model relates to the field of product packaging technology, and in particular to a novel paper tape structure. Background Technology
[0002] Packing straps are a widely used packaging material, and there are many types, mainly including paper straps, plastic straps, and metal straps. Paper straps are made from natural plant fibers and are renewable, recyclable, and biodegradable. Plastic straps are usually made from molten PP or PET material granules and then extruded. Metal straps are usually made from high-quality cold-rolled steel sheets. In daily life, the handling, transportation, and storage of goods typically require the use of PP straps, PET straps, or metal straps for bundling.
[0003] The existing technology has at least the following problems: First, although paper tape is environmentally friendly, it has low strength and is easy to tear and break. Second, the recycling of plastic and metal strapping is difficult and risky, and the cost is also high. In most cases, these plastic or metal strapping will become landfill waste, and some will enter rivers, lakes and oceans, which will harm the ecological environment and wildlife. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by developing a novel paper tape structure. This invention not only improves the strength of the paper tape but also enables it to be recycled and reused, effectively enhancing the performance of the paper tape.
[0005] The technical solution of this utility model to solve the technical problem is as follows: a novel paper tape structure, including a paper tape body, the paper tape body including a U-shaped surface layer and two sets of folded parts, the end of the U-shaped surface layer is connected to the first end of the folded part, and the folded part is disposed inside the U-shaped surface layer.
[0006] As an optimization, the fold section has a single layer. This reduces the overall thickness of the paper tape while maintaining its strength, thus lowering production costs and making it suitable for packing small items or carrying them by hand.
[0007] As an optimization, the folding section has two layers, with the second ends of the two sets of folding sections tightly touching each other. By setting the double-layered folding section, the tensile strength and stiffness of the paper tape can be improved, while maintaining the strength of the paper tape and reducing the overall thickness of the paper tape, thus reducing production costs. It can be used for packaging medium-sized goods or for carrying by hand.
[0008] As an optimization, the second end of the fold is positioned between the U-shaped surface layer and the first end of the fold. By setting a double-layer fold, the tensile strength and stiffness of the paper tape can be improved, while maintaining the strength of the paper tape and reducing the overall thickness of the paper tape, thereby reducing production costs. It can be used for packaging medium-sized goods or for carrying by hand.
[0009] As an optimization, the fold section has at least three layers, folded in an "S" or "e" shaped path. By setting multiple layers of fold sections, the strength of the paper tape can be further enhanced, the interlayer cohesion of the paper tape can be strengthened, the tensile strength and stiffness of the paper tape can be significantly improved, and the resistance to side tearing of the paper tape can be improved, making it suitable for packaging and bundling large goods.
[0010] As an optimization, a first adhesive layer is provided on both sides of the fold. By setting the first adhesive layer, the strength of the paper tape core can be enhanced, the interlayer cohesion of the paper tape can be strengthened, and the internal waterproofing ability of the paper tape can be improved, thereby improving the resistance to side tearing of the paper tape.
[0011] As an optimization, a second adhesive layer is provided on the outside of the U-shaped surface layer. By setting the second adhesive layer, the U-shaped surface layer can be wrapped, improving the thermal adhesion of the paper tape, facilitating heat bonding during packaging, and also improving the external waterproofing of the paper tape, thereby improving the paper tape's resistance to side tearing.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] By designing the paper tape body, it can be recycled and reused, minimizing environmental impact. The U-shaped surface layer can wrap around the folds, maintaining consistency in feel and appearance. The complete double-sided layer enhances the strength of the paper tape and improves its waterproof capability. The folds serve as the load-bearing structure of the paper tape and, together with the U-shaped surface layer, form a multi-layer paper tape structure, further enhancing its strength, interlayer cohesion, tensile strength, stiffness, and resistance to side tearing.

[0019] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0020] Example 1
[0021] Figure 1 and Figure 2 As one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a novel paper tape structure includes a paper tape body 1, characterized in that: the paper tape body 1 includes a U-shaped surface layer 2 and two sets of folded portions 3, the end of the U-shaped surface layer 2 is connected to the first end of the folded portion 3, and the folded portion 3 is disposed inside the U-shaped surface layer 2.
[0022] By setting the paper tape body 1, it can be recycled and reused, minimizing environmental harm; by setting the U-shaped surface layer 2, it can wrap the folded part 3, maintaining consistency in feel and appearance, and the complete upper and lower double-sided layers can enhance the strength of the paper tape and improve its waterproof ability; by setting the folded part 3, it can serve as the main load-bearing body of the paper tape, and can work with the U-shaped surface layer 2 to form a dense structure of multiple layers of paper tape, further enhancing the strength of the paper tape, strengthening the interlayer cohesion of the paper tape, improving the tensile strength and stiffness of the paper tape, and improving the anti-tear performance of the paper tape.
[0023] like Figure 1 and Figure 2 As shown, the fold 3 has one layer. This can reduce the overall thickness of the paper tape while maintaining its strength, thereby reducing production costs. It can be used for packaging small items or for carrying by hand.
[0024] like Figure 1 and Figure 2 As shown, a first adhesive layer 4 is provided on both sides of the folded portion 3. By providing the first adhesive layer 4, the strength of the paper tape core can be enhanced, the interlayer cohesion of the paper tape can be strengthened, and the internal waterproofing ability of the paper tape can be improved, thereby improving the anti-tear performance of the paper tape.
[0025] like Figure 1 and Figure 2 As shown, a second adhesive layer 5 is provided on the outer side of the U-shaped surface layer 2. The second adhesive layer 5 is a hot melt adhesive. By setting the second adhesive layer 5, the U-shaped surface layer 2 can be wrapped, improving the thermal adhesion of the paper tape, facilitating heat bonding during packaging, and improving the external waterproof capability of the paper tape, thereby improving the anti-tear performance of the paper tape.
[0026] Example 2
[0027] like Figure 3 As shown, the difference from Embodiment 1 is that the second ends of the two sets of folded portions 3 are tightly pressed together. By setting double-layered folded portions 3, the tensile strength and stiffness of the paper tape can be improved, while maintaining the strength of the paper tape, the overall thickness of the paper tape can be reduced, and the production cost can be reduced. It can be used for packaging medium-sized goods or for carrying by hand.
[0028] Example 3
[0029] like Figure 4 As shown, the difference between this embodiment and Embodiment 2 is that the folded portion 3 has two layers, with the second end of the folded portion 3 positioned between the U-shaped surface layer 2 and the first end of the folded portion 3. By providing a double-layered folded portion 3, the tensile strength and stiffness of the paper tape can be improved, while maintaining the strength of the paper tape and reducing the overall thickness of the paper tape, thereby reducing production costs. This design allows it to be used for packaging medium-sized goods or for carrying by hand.
[0030] Example 4
[0031] The difference between this embodiment and embodiments 1-3 is that the folded portion 3 has at least three layers, and the folded portion 3 is folded in an "S" or "e" shaped path. By setting multiple layers of folded portions 3, a dense structure can be formed, which further enhances the strength of the paper tape, strengthens the interlayer cohesion of the paper tape, improves the waterproof effect, significantly improves the tensile strength and stiffness of the paper tape, and improves the anti-tear performance of the paper tape, making it suitable for packaging and bundling large goods.
[0032] During production, the U-shaped surface layer 2 and the two sets of folded portions 3 are formed by folding paper as a single unit. When the folded portions 3 are folded into shape, a first adhesive layer 4 is applied to both sides of the folded portions 3, ensuring a firm bond inside the folded portions 3. Simultaneously, when the U-shaped surface layer 2 is bent into shape, the two sets of folded portions 3 are firmly bonded together. Finally, a second adhesive layer 5 is applied to the outside of the paper tape body 1 and then dried to further enhance the stiffness of the paper tape and improve its thermal adhesion during packaging. This invention not only improves the strength of the paper tape but also allows for recycling, effectively enhancing the performance of the paper tape.
