Technical Field

[0001] This utility model relates to the field of cable ties, and in particular to a double-sided adhesive kraft paper cable tie. Background Technology

[0002] Cable ties are frequently used to secure items in industrial production, logistics, and daily life. While traditional plastic cable ties are highly adhesive, they are difficult to degrade, posing a significant environmental pollution problem. Existing kraft paper cable ties are mostly designed with adhesive on one side, which can easily loosen in scenarios requiring high binding strength. Furthermore, some kraft paper cable ties have a simple structure, making it difficult to balance strength and flexibility.

[0003] Therefore, a double-sided adhesive kraft paper tape is proposed, which combines high strength, high flexibility, environmental friendliness, and strong adhesion to solve the above problems. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art and provides a double-sided adhesive kraft paper tape.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a double-sided adhesive kraft paper tape, comprising: a kraft paper base layer, wherein adhesive layers are provided on both sides of the kraft paper base layer, and release paper is attached to the side of the adhesive layer away from the kraft paper base layer;

[0006] The kraft paper base layer adopts a three-layer composite structure, consisting of a high-strength kraft paper layer, a buffer fiber layer, and a flexible kraft paper layer from the outside to the inside. The three layers are bonded and fixed together with environmentally friendly plant-based adhesive.

[0007] In a preferred embodiment of this utility model, the kraft paper base layer includes at least four types, and the lengths of each type are 100mm, 150mm, 200mm, 250mm and 300mm respectively.

[0008] In a preferred embodiment of this utility model, the width of the kraft paper base layer of all four models is 10mm.

[0009] In a preferred embodiment of this utility model, the adhesive layer has a length of 30mm and a width of 10mm.

[0010] In a preferred embodiment of the present invention, the adhesive layer includes a first adhesive layer and a second adhesive layer, wherein the first adhesive layer is disposed on one side surface of the kraft paper base layer and the second adhesive layer is disposed on the other side surface of the kraft paper base layer.

[0011] In a preferred embodiment of the present invention, the release paper includes a first release paper and a second release paper, wherein the first release paper is adhered to the first adhesive layer and the second release paper is adhered to the second adhesive layer.

[0012] In a preferred embodiment of this utility model, the length of the first release paper is 35mm and the width is 10mm.

[0013] In a preferred embodiment of this utility model, the second release paper has a length of 20mm-30mm and a width of 10mm.

[0014] In a preferred embodiment of this invention, the average static shear adhesion force of the adhesive layer is 2.9 N / 10 mm. 2 The average peel strength at 180° is 21.1 N / 10 mm.

[0015] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0016] This invention provides double-sided adhesive tape and release paper on both sides of the kraft paper base, enabling the tape to adhere to both sides. In scenarios where high binding strength is required, it provides stronger adhesion, effectively avoiding the loosening problem that may occur with single-sided adhesive, and improving the stability and reliability of binding.

[0017] Meanwhile, the kraft paper base layer adopts a three-layer composite structure, consisting of a high-strength kraft paper layer, a cushioning fiber layer, and a flexible kraft paper layer from the outside to the inside. The three layers are bonded and fixed together with environmentally friendly plant-based adhesive. The outer high-strength kraft paper layer ensures the overall tensile strength, the middle cushioning fiber layer improves bending resistance and cushioning performance, and the inner flexible kraft paper layer enhances adhesion.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a double-sided adhesive kraft paper tape includes: a kraft paper base layer 1, adhesive layers 2 on both sides of the kraft paper base layer 1, and release paper 3 attached to the side of the adhesive layer 2 away from the kraft paper base layer 1. The double-sided adhesive tape and release paper 3 are provided on both sides of the kraft paper base layer 1, enabling the tape to be adhered to both sides. In scenarios requiring high binding strength, this provides stronger adhesion, effectively avoiding the loosening problem that may occur with single-sided adhesive, and improving the stability and reliability of the binding.

[0027] Specifically, the adhesive layer 2 includes a first adhesive layer 20 and a second adhesive layer 21. The adhesive layer 2 has a length of 30 mm and a width of 10 mm. The first adhesive layer 20 is disposed on one side of the kraft paper base layer 1, and the second adhesive layer 21 is disposed on the other side of the kraft paper base layer 1. The release paper 3 includes a first release paper 30 and a second release paper 31. The first release paper 30 is attached to the first adhesive layer 20, and the second release paper 31 is attached to the second adhesive layer 21. The first release paper 30 has a length of 35 mm and a width of 10 mm, and the second release paper 31 has a length of 20 mm-30 mm and a width of 10 mm.

[0028] The kraft paper base layer 1 adopts a three-layer composite structure, consisting of a high-strength kraft paper layer 10, a cushioning fiber layer 11, and a flexible kraft paper layer 13 from the outside to the inside. The kraft paper base layer 1 is composed of a high-strength kraft paper layer 10, a cushioning fiber layer 11, and a flexible kraft paper layer 13. It has high tensile strength, can withstand a certain amount of tension, and has good flexibility, making it easy to wrap around items of different shapes.

[0029] The three layers are bonded and fixed together with environmentally friendly plant-based adhesive. The kraft paper base layer 1 adopts a three-layer composite structure, and each layer is bonded with environmentally friendly plant-based adhesive. It can be naturally degraded and will not cause long-term pollution to the environment.

[0030] Specifically, the kraft paper base layer 1 includes at least four models, each with corresponding lengths of 100mm, 150mm, 200mm, 250mm, and 300mm. The width of the kraft paper base layer 1 in all four models is 10mm. It provides multiple length models with a uniform width of 10mm to meet the binding needs of items of different sizes. The double-sided adhesive layer 2 is designed with release paper 3. When using it, you only need to tear off the release paper 3 to perform the adhesive operation, which is simple and convenient.

[0031] In a preferred embodiment of this invention, the average static shear adhesion force of the adhesive layer 2 is 2.9 N / 10 mm. 2 The average 180° peel strength is 21.1 N / 10 mm, which ensures that the bound items are not easily loosened or detached during handling and storage, and can stably maintain the binding state.

[0032] When using this utility model, select a double-sided adhesive kraft paper cable tie of the appropriate length according to the circumference of the item to be bound and the binding requirements. Tear off the first release paper 30 and the second release paper 31 in sequence to fully expose the first adhesive layer 20 and the second adhesive layer 21. Wrap the kraft paper base layer 1 around the item to be bound, adjust the position so that the first adhesive layer 20 and the second adhesive layer 21 are accurately aligned and adhered. Press the adhered part of the adhesive layer 2 with your hand and press continuously for a few seconds to ensure that the adhesive layer 2 is fully in contact and firmly adhered, thus completing the binding.

[0033] Example 1: Land Transportation Logistics Parcel Binding

[0034] In land transportation logistics scenarios, when securing packages containing small electronic components (containing small accessories such as resistors and capacitors, with an outer circumference of approximately 200mm after being wrapped in bubble wrap), double-sided adhesive kraft paper straps with a length of 250mm are selected for securing the packages, taking into account the possibility of collisions and falling during transportation.

[0035] During operation, tear open the first release paper 30 and the second release paper 31, wrap the cable tie around the package to ensure precise adhesion between the first adhesive layer 20 and the second adhesive layer 21. Press the adhered area continuously for 5 seconds to ensure full adhesion. After binding, simulate a common drop scenario in land transportation by dropping the package vertically from a height of 1.5 meters (equivalent to the common height from the edge of a truck bed to the ground) onto a concrete surface, repeating this 3 times (simulating multiple collisions during transportation).

[0036] The results showed that the cable ties did not open or break after each drop and impact: the adhesive layer, with a strength of 2.9 N / 10 mm, effectively prevented them from breaking. 2 The static shear adhesion and 180° peel strength of 21.1 N / 10 mm ensure that the material remains tightly bonded and does not separate when subjected to impact. The three-layer composite structure of the kraft paper base (high-strength kraft paper layer 10 provides tensile strength, buffer fiber layer 11 absorbs impact energy, and flexible kraft paper layer 13 enhances overall toughness) effectively withstands the instantaneous tensile and impact forces when falling, and the base layer shows no tearing or breakage.

[0037] The test showed that the double-sided adhesive kraft paper cable tie can maintain a stable binding state when faced with collisions or drops during land transportation, preventing the package from coming apart, ensuring the safety of the goods during transportation, and the cable tie itself is not damaged, which meets the requirements of land logistics for binding reliability.

[0038] Example 2: Binding of Daily Necessities

[0039] In daily life, when organizing and binding books, if the circumference of the stacked books is approximately 180mm, a 200mm long kraft paper cable tie can be selected. After tearing off the first release paper 30 and the second release paper 31, wrap the cable tie around the book, making the first adhesive layer 20 and the second adhesive layer 21 adhere together. Press the adhesive area for about 3 seconds to achieve a secure binding of the books. Because the cable tie is flexible, it will not damage the book cover, and the environmentally friendly material also avoids environmental pollution.

[0040] Example 3: Temporary Fixation of Industrial Articles

[0041] In a factory, when temporarily securing and moving small metal parts, if the assembled part has a circumference of approximately 230mm, a 250mm long cable tie can be used. During operation, tear off the release paper 3, wrap the cable tie around the part, ensuring the two adhesive layers 2 adhere, and press firmly. The adhesive layer provides 22.9N / 10mm. 2 The static shear adhesion ensures that parts will not scatter during handling. Furthermore, when disassembly is required later, the adhesive joints can be easily separated without damaging the surface of the parts. The removed cable ties are biodegradable and do not generate industrial waste pollution.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
