Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically a box sealing tape. Background Technology

[0002] To ensure the safety and integrity of goods before use, manufacturers typically package them before transportation or storage. As part of the packaging process, sealing tape is usually used to seal the boxes to ensure their airtightness and containment. However, with the widespread use of sealing tape in the packaging process, some problems associated with traditional sealing tape have begun to emerge.

[0003] On the one hand, traditional sealing tape, to ensure sufficient strength for a secure seal, generally uses polyethylene (PE plastic) and fiberglass (fiberglass cloth) as its main materials. However, these materials are difficult to degrade naturally or be recycled, leading to the long-term accumulation of used sealing tape waste and causing environmental pollution. On the other hand, in high-temperature or low-temperature environments, the adhesive layer inside traditional sealing tape may experience delamination or seepage, causing the sealing tape to detach from the surface of the packaging box or damage the surface structure.

[0004] In the existing technology, some sealing tapes use pure paper substrate in pursuit of environmental protection, which results in insufficient overall strength of the sealing tape and makes it difficult to meet the reliability requirements of heavy packaging or long-distance transportation. Utility Model Content

[0005] To address the above problems, this utility model provides a sealing tape that, while ensuring sufficient strength, not only achieves zero-plasticization manufacturing by completely eliminating the use of plastic or plastic-based materials during production, but also avoids damaging the packaging surface of goods, making the packaging process more environmentally friendly and reliable.

[0006] This utility model provides a sealing tape, including a substrate layer, an adhesive layer, and a film layer; wherein, the substrate layer is made of cotton cloth; the adhesive layer is directly attached to one side of the substrate layer; and the film layer is made of paper or aluminum foil and is attached to the other side of the substrate layer.

[0007] Optionally, the weather resistance temperature limit of the adhesive layer is -20℃ to 100℃.

[0008] Optionally, a release layer is also provided on the surface of the paper.

[0009] Optionally, the thickness of the substrate layer and the film layer ranges from 0.05mm to 0.2mm, and the thickness of the adhesive layer ranges from 0.005mm to 0.2mm.

[0010] The sealing tape provided by this utility model uses cotton cloth as the base layer and paper or aluminum foil as the film layer. This not only ensures sufficient overall strength of the sealing tape, preventing breakage when workers pull and attach it to the surface of the packaging box, but also achieves zero plasticization during the manufacturing process, avoiding the generation of large amounts of non-biodegradable waste after use, thus reducing the environmental impact of the sealing tape. Furthermore, the paper or aluminum foil film layer not only prevents glue seepage during use and avoids adhesion between stacked packaging boxes, but also provides good release properties, making the sealing tape more convenient and efficient to use.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] To ensure the packaging of goods is sufficiently reliable and to make the packaging materials more environmentally friendly to avoid serious environmental impact from packaging waste, this embodiment provides a sealing tape 100A, comprising: a substrate layer 2, an adhesive layer 3, and a film layer 1. The substrate layer 2 is made of cotton cloth; the adhesive layer 3 is directly attached to one side of the substrate layer 2; and the film layer 1 is made of paper or aluminum foil and is attached to the other side of the substrate layer 2.

[0015] During the use of the sealing tape 100A, the substrate layer 2, as the main load-bearing carrier and support platform for the adhesive layer 3, needs to have a certain tensile strength to prevent the sealing tape 100A from easily breaking during pulling and pasting. Simultaneously, the substrate layer 2 also needs to maintain a certain degree of flexibility, allowing the sealing tape 100A to be applied to various types of packaging boxes without breaking due to bending. Therefore, in this embodiment, the substrate layer 2 is made of cotton cloth. Besides achieving the aforementioned tensile strength and flexibility, the cotton substrate layer 2 can also undergo natural degradation in a relatively short time. Compared to traditional sealing tapes 100A that use fiberglass cloth or polyethylene to make the substrate layer 2, the materials used in the substrate layer 2 of the sealing tape 100A provided in this embodiment are more environmentally friendly, which to some extent reduces the manufacturing cost and waste disposal cost of the sealing tape 100A.

[0016] refer to Figure 1 The adhesive layer 3 is directly attached to one side of the substrate layer 2, formed by the curing of adhesive applied to one side of the substrate layer 2. The finished sealing tape 100A is specifically designed to adhere the adhesive layer 3 to the outer surface of the packaging box to ensure the goods are securely enclosed inside. To ensure good adhesion of the adhesive layer 3 to the packaging box surface under both high and low temperature conditions, the weather resistance temperature of the adhesive layer 3 in this embodiment is -20℃ to 100℃. Due to the wide weather resistance temperature range of the adhesive layer 3, when the sealing tape 100A is used in a normal low-temperature environment, the adhesive layer 3 will not easily cure and detach from the substrate layer 2 or the packaging box surface, thus preventing goods from leaking out of the packaging box.

[0017] Considering that packaging boxes sealed with sealing tape 100A may be stacked during storage or transportation, with the sealing tape 100A on the outer surface of the packaging boxes positioned between adjacent boxes, if the stacked packaging boxes are transferred to a high-temperature environment for storage or transportation, the conventional adhesive layer 3 may melt due to the high temperature, causing it to seep out from the surface or sides of the substrate layer 2, ultimately resulting in glue flowing between the outer surfaces of the stacked packaging boxes. After the glue solidifies again, the boxes will stick together, damaging the surface of the boxes during separate handling and affecting their packaging appearance. In this embodiment, the high weather resistance temperature range of the adhesive layer 3 prevents it from melting at conventional high temperatures, thus preventing the stacked packaging boxes from being damaged due to glue adhesion.

[0018] Considering that the adhesive applied to one side of the substrate layer 2 requires a certain curing time to form the adhesive layer 3, or that the packaging boxes packaged by the sealing tape 100A may be transported to extreme environments, causing the adhesive in the adhesive layer 3 of the sealing tape 100A to melt. Furthermore, since the substrate layer 2 in this embodiment is made of porous and easily absorbent cotton cloth, there is a possibility that the liquid adhesive could penetrate from the initial coating surface of the substrate layer 2 to the other side, leading to adhesion between adjacent packaging boxes after stacking, ultimately damaging the box surfaces during separate handling. Therefore, in this embodiment, the sealing tape 100A also includes a film layer 1, which is attached to one side of the substrate layer 2 relative to the adhesive layer 3, and the film layer 1 is attached to the other side of the substrate layer 2. The film layer 1 is made of paper or aluminum foil, which prevents the glue that has not yet solidified or the glue that has melted from the glue layer 3 at extreme temperatures from penetrating through the film layer 1 and seeping onto the surface of other packaging boxes. This prevents or reduces damage to the packaging boxes caused by mutual adhesion when they are stacked.

[0019] In this embodiment, to facilitate the assembly, handling, and use of the sealing tape 100A, the sealing tape 100A can be fixed to the outer surface of the take-up drum 100B in a layered manner by being wound around the outer surface of the take-up drum 100B. (Reference) Figure 1 The take-up drum 100B is a hollow circular ring. The width of the outer circumference of the take-up drum 100B is the same as or slightly larger than the width of the sealing tape 100A. When one end of the sealing tape 100A is fixed to a certain point on the outer circumference of the take-up drum 100B and winding begins, the adhesive layer 3 of the sealing tape 100A first adheres to the outermost surface of the take-up drum 100B. Subsequently, after the sealing tape 100A has wrapped around the take-up drum 100B once, the adhesive layer 3 of the sealing tape 100A begins to cover the side of the film layer 1 away from the take-up drum 100B and continues to be layered and wound around the take-up drum 100B. Finally, when the layers of sealing tape 100A on the take-up drum 100B are stacked and wound to a fixed thickness, the sealing tape 100A can be cut, so that the take-up drum 100B and the sealing tape 100A layered and wound on its outer circumference form a fixed whole. In this embodiment, the take-up drum 100B comes from the molded part. The reserved opening in the middle of the take-up drum 100B allows the worker to hold it and complete the packaging work of the packaging box, or to fix the sealing tape 100A together with the take-up drum 100B to the preset position of the sealing machine (not shown in the figure) through this opening. The sealing machine then conveys the packaging box and pulls the sealing tape 100A to complete the packaging process of the packaging box.

[0020] When the sealing tape 100A is wound and fixed on the take-up drum 100B, since the adhesive surface of the adhesive layer 3 is in contact with the outer surface of the film layer 1, when the sealing tape 100A is used, it is necessary to pull the outermost end of the sealing tape 100A to separate the adhesive layer 3 from the surface of the film layer 1. In order to ensure that the sealing tape 100A can be smoothly unwound from the take-up drum 100B during the pulling process, and to maintain a good adhesive effect after straightening the adhesive layer 3 for packaging the box, the sealing tape 100A needs to have a certain "release" property. Specifically, in this embodiment, the adhesive layer 3 can be easily and conveniently peeled off from the surface of the film layer 1 while maintaining the original appearance and adhesive effect of the adhesive layer 3 as much as possible. In this embodiment, when aluminum foil is used to make the film layer 1 of the sealing tape 100A, the aluminum foil has a low surface energy and a dense, smooth surface with a certain degree of adhesive repellency, giving it release capability. This allows the adhesive layer 3 of the sealing tape 100A wound on the take-up drum 100B to easily detach from the surface of the film layer 1. Finally, the adhesive layer 3 is used to bond the sealing tape to the packaging box to complete the packaging. When paper is used to make the film layer 1 of the sealing tape 100A, the paper needs to have a certain strength and flexibility to ensure its abrasion resistance and tear resistance, preventing the sealing tape 100A from being easily torn or broken during the pulling process.

[0021] Due to the porous nature and high surface energy of paper, when it overlaps with adhesive layer 3, the small amount of moisture contained in adhesive layer 3 may cause the paper to be over-wetted, reducing its strength and causing the sealing tape 100A to tear during the pulling process. On the other hand, adhesive layer 3 may penetrate to the other side of film layer 1, causing it to stick to the cotton cloth of substrate layer 2 or another layer of adhesive layer 3, ultimately making it difficult for sealing tape 100A to be easily peeled off and unwound from the outer circumference of take-up drum 100B. Therefore, in this embodiment, a release agent is also coated on the surface of the paper, forming a release layer between the adhesive layer 3 and the paper's contact surface. This significantly reduces the surface energy of the paper, preventing excessive adhesion between adhesive layer 3 and the paper, thus allowing adhesive layer 3 to be easily peeled off from take-up drum 100B without causing the sealing tape 100A to tear or adhesive layer 3 residue. Since silicone oil has good release properties and is inexpensive, silicone oil is preferred as the release agent in this embodiment. In other embodiments, other types of release agents may be selected according to the actual use environment and release requirements, and no specific restrictions are imposed here.

[0022] When faced with a lateral pulling force on one end of the sealing tape 100A, to ensure that the overall strength of the sealing tape 100A is sufficient to prevent it from tearing, and to ensure that the sealing tape 100A has sufficient adhesiveness to package the box, in this embodiment, the thickness of the film layer 1 and the substrate layer 2 in the sealing tape 100A should be no less than 0.05mm, and the thickness of the adhesive layer 3 should be no less than 0.005mm.

[0023] In this embodiment, the sealing tape 100A wound on the outer surface of the take-up drum 100B can be fixed at a preset position on the sealing machine and work together with the sealing machine to complete the packaging process of the box. Specifically, when the box passes through the inside of the sealing machine, the outermost end of the sealing tape 100A on the take-up drum 100B adheres to the preset position of the sealing machine. Then, the sealing machine pulls part of the sealing tape 100A out from the take-up drum 100B and straightens it. Subsequently, the adhesive layer 3 is laid flat on the position of the box to be sealed inside the sealing machine. Finally, the sealing tape 100A, which is attached to the box and the take-up drum 100B respectively, is cut and separated by the cutting blade of the sealing machine, thereby realizing the automatic packaging of the box. In order to ensure that the sealing machine can cut the sealing tape 100A smoothly, and considering the manufacturing cost of the sealing tape 100A, in this embodiment, the film layer 1, the substrate layer 2 and the adhesive layer 3 in the sealing tape 100A are all no larger than 0.2mm.

[0024] In this embodiment, all materials used in the manufacture of the sealing tape 100A are environmentally friendly. At the end of the service life of the sealing tape 100A, these environmentally friendly materials enable the waste of the sealing tape 100A to degrade quickly into harmless substances in the natural environment, ultimately returning to nature. Simultaneously, some components of the sealing tape 100A can be recycled for reuse, effectively conserving raw resources.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
