Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive tape technology, specifically a tensile-resistant, environmentally friendly, and water-resistant kraft paper tape. Background Technology
[0002] As people's living standards improve, they are paying more and more attention to environmental protection, and the packaging industry is also placing higher demands on the environmental performance and mechanical strength of adhesive tapes.
[0003] Currently available kraft paper tapes for packaging generally improve tear resistance by using a double-layer kraft paper structure with reinforcing layers of nylon yarn and glass fiber yarn sandwiched between them. The principle is to utilize the high toughness of the nylon yarn and the rigidity of the glass fiber yarn to form a mesh support.
[0004] However, nylon yarn and glass fiber yarn are difficult to degrade by conventional means, resulting in poor environmental performance. Furthermore, due to their sharp and easily broken characteristics, glass fiber yarn can easily cause adverse effects on operators during recycling, exacerbating the difficulty of recycling and increasing recycling and reprocessing costs. Utility Model Content
[0005] The purpose of this utility model is to provide a tensile-resistant and environmentally friendly wet-water kraft paper tape that improves the environmental friendliness of the tape while ensuring tear resistance.
[0006] To achieve the above objectives, the solution of this utility model is: a tensile-resistant, environmentally friendly, and water-resistant kraft paper tape, comprising a first kraft paper layer, a first adhesive, a yarn layer made of plant fiber material, a second kraft paper layer, and a second adhesive;
[0007] The yarn layer is disposed between the first kraft paper layer and the second kraft paper layer and bonded together with the first adhesive, and the second adhesive is applied to the first kraft paper layer or the second kraft paper layer.
[0008] The yarn layer consists of multiple first yarns and multiple second yarns. Each first yarn is straight, and each second yarn is serrated. The multiple first yarns extend along the length of the tape. Each second yarn is interwoven or overlapped with the adjacent multiple first yarns. The serrations formed by each second yarn face the width of the tape.
[0009] In a preferred embodiment, the plant fiber material includes one, two, or all three of paper fiber, bamboo fiber, and cotton and linen fiber.
[0010] In a preferred embodiment, the first adhesive is a polyacrylate adhesive.
[0011] In a preferred embodiment, the second adhesive is a starch adhesive.
[0012] In a preferred embodiment, the yarn layer is composed of multiple third yarns, each of which is wavy, with the crests and troughs of each third yarn facing the length or width of the tape. The third yarns are interwoven or staggered in pairs, or multiple third yarns are interwoven or staggered in pairs.
[0013] In a preferred embodiment, the yarn layer is composed of a fourth yarn, and multiple fourth yarns are interwoven to form a honeycomb structure.
[0014] In a preferred embodiment, the yarn layer is composed of multiple fifth yarns and multiple sixth yarns. Each fifth yarn is straight, and each sixth yarn is wavy. The multiple fifth yarns extend along the length or width of the tape, and the crests and troughs of each sixth yarn face the length or width of the tape. Each fifth yarn and the multiple sixth yarns are interwoven or staggered.
[0015] After adopting the above solution, the beneficial effects of this utility model are as follows:
[0016] The yarn layer of this invention is disposed between a first kraft paper layer and a second kraft paper layer and bonded together with a first adhesive. A second adhesive is applied to either the first or second kraft paper layer. The yarn layer consists of multiple first yarns and multiple second yarns. Each first yarn is straight, and each second yarn is serrated. The multiple first yarns extend along the length of the tape, and each second yarn is interwoven or staggered with adjacent first yarns. The serrations formed by each second yarn face the width of the tape, allowing the yarn layer to better disperse stress when subjected to tensile force, thereby improving the overall tear resistance of the tape. Furthermore, because the yarn layer is made of plant fiber material, it is more environmentally friendly and easier to recycle, which helps reduce recycling and remanufacturing costs.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0027] Example 1:
[0028] Example 1 provides a tensile-resistant, environmentally friendly, wet-wet kraft paper tape, such as... Figure 1 and Figure 2 As shown, it includes a first kraft paper layer 1, a first glue 3, a yarn layer 5 made of plant fiber material, a second kraft paper layer 2, and a second glue 4;
[0029] The yarn layer 5 is disposed between the first kraft paper layer 1 and the second kraft paper layer 2 and is bonded together with the first glue 3. The second glue 4 is applied to the first kraft paper layer 1 or the second kraft paper layer 2.
[0030] The yarn layer 5 is composed of multiple first yarns 51 and multiple second yarns 52. Each first yarn 51 is straight, and each second yarn 52 is serrated. The multiple first yarns 51 extend along the length of the tape, and each second yarn 52 is interwoven or overlapped with the adjacent multiple first yarns 51. The serrations formed by each second yarn 52 face the width of the tape.
[0031] In Example 1, the yarn layer 5 is made of plant fiber material, and the first kraft paper layer 1 and the second kraft paper layer 2 are also made of plant fiber, making the tape more environmentally friendly, easier to recycle and reproduce, and helping to reduce costs.
[0032] Furthermore, in Embodiment 1, multiple first yarns 51 in the yarn layer 5 extend along the length of the tape, providing tensile strength in the length direction of the tape. Each second yarn 52 is serrated and interwoven or staggered with multiple adjacent first yarns 51, providing tensile strength in the width direction of the tape. This allows the yarn layer 5 to better disperse stress when subjected to external force, thereby improving the overall tensile strength and tear resistance of the tape.
[0033] The yarn layer 5 is firmly bonded between the first kraft paper layer 1 and the second kraft paper layer 2 using the first adhesive 3, ensuring the stability of the tape during use. Simultaneously, the second adhesive 4 is applied to either the first kraft paper layer 1 or the second kraft paper layer 2, ensuring the tape can firmly adhere to various object surfaces.
[0034] Furthermore, the plant fiber material includes one, two, or all three of paper fiber, bamboo fiber, and cotton and linen fiber, which ensures tensile strength while being more environmentally friendly.
[0035] Furthermore, the first adhesive 3 is a polyacrylate adhesive, but it is not limited to this. The yarn layer 5 can be bonded to the first kraft paper layer 1 and the second kraft paper layer 2 by a heat pressing process, which is simple to operate.
[0036] Furthermore, the second adhesive 4 is a starch adhesive. In Embodiment 1, the second adhesive 4 can be an existing starch adhesive, which is coated onto the first kraft paper layer 1 or the second kraft paper layer 2, so that the starch adhesive becomes sticky when it comes into contact with water, making it convenient to use.
[0037] Example 2:
[0038] like Figure 3 and Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that the yarn layer 5 in Embodiment 2 is composed of multiple third yarns 53, each third yarn 53 is wavy, and the crests and troughs of each third yarn 53 are oriented towards the length or width of the tape. The third yarns 53 are interwoven or staggered in pairs, or multiple third yarns 53 are interwoven or staggered in pairs.
[0039] Figure 3 The crests and troughs of each third yarn 53 shown are oriented towards the length of the tape. Of course, users can also set the crests and troughs of each third yarn 53 to face the width of the tape according to actual needs, such as... Figure 4 As shown. In Example 2, the third yarn 53 is wavy, which allows the yarn to disperse stress through deformation when under force, reducing the risk of fiber breakage. The third yarns 53 are interwoven in pairs or staggered, or multiple third yarns 53 are interwoven or staggered, so that the yarns support each other and improve the overall tear resistance and tensile strength.
[0040] Example 3:
[0041] like Figure 5 As shown, the difference between Embodiment 3 and Embodiment 1 is that the yarn layer 5 in Embodiment 3 is composed of fourth yarns 54, and multiple fourth yarns 54 are interwoven to form a honeycomb structure.
[0042] In Example 3, multiple fourth yarns 54 are interwoven to form a honeycomb structure. Specifically, the yarns can be woven into a honeycomb structure on the production line, or commercially available woven yarns can be directly used to cover the first kraft paper layer 1 and the second kraft paper layer 2. Users can make the settings according to actual production.
[0043] The hexagonal units with a honeycomb structure can disperse stress through deformation, thereby improving the overall tear and tensile resistance.
[0044] Example 4:
[0045] like Figure 6 and Figure 7 As shown, the difference between Embodiment 4 and Embodiment 1 is that the yarn layer 5 in Embodiment 4 is composed of multiple fifth yarns 55 and multiple sixth yarns 56. Each fifth yarn 55 is straight, and each sixth yarn 56 is wavy. The multiple fifth yarns 55 extend along the length or width of the tape, and the crests and troughs of each sixth yarn 56 face the length or width of the tape. Each fifth yarn 55 and the multiple sixth yarns 56 are interwoven or staggered.
[0046] Figure 6 Each fifth yarn 55 extends along the length of the tape, and the crests and troughs of each sixth yarn 56 face the length of the tape. Of course, users can also adjust the arrangement so that each fifth yarn 55 extends along the width of the tape, and the crests and troughs of each sixth yarn 56 face the width of the tape, as needed. Figure 7 As shown in Example 4, in yarn layer 5, multiple fifth yarns 55 extend along the length of the tape, providing tensile strength in the length direction. Each sixth yarn 56 is wavy, and multiple sixth yarns 56 are arranged along the length of the tape. The crests and troughs of each sixth yarn 56 face the length direction of the tape, providing tensile strength in the width direction. Each fifth yarn 55 and multiple sixth yarns 56 are interwoven or staggered, so that when yarn layer 5 is subjected to external tension, stress can be better dispersed, thereby improving the overall tensile strength and tear resistance of the tape.
[0047] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.
[0048] The above description is only a preferred embodiment of this utility model and is not a limitation on the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
