Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive tape technology, specifically a wavy edge foam adhesive tape. Background Technology
[0002] In the logistics and express delivery industry, tape is used to seal cardboard boxes. Like ordinary corrugated cardboard boxes, tape can be used to securely seal the lid, ensuring that the contents do not fall out during transportation. Whether it's small e-commerce parcels or large industrial product packaging boxes, tape is an indispensable sealing tool.
[0003] Existing adhesive tapes also have the following problems: Traditional release paper has straight, smooth edges, making it difficult for fingers to apply precise pressure, and users often experience slippage when pinching the release paper. Furthermore, it is easy to accidentally pull up the foam base layer, damaging the foam, contaminating the adhesive layer with foreign matter, compromising the tape's initial performance, and consequently affecting the subsequent bonding effect.
[0004] Therefore, there is an urgent need for a wavy edge foam tape to solve the above problems. Utility Model Content
[0005] Based on the above, the purpose of this utility model is to provide a wavy edge foam tape to solve the problems of tape being difficult to pinch and tear, and the foam base layer being easily pulled up.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A wavy-edged foam tape, comprising:
[0008] The tape body includes release paper, foam base layer and adhesive layer connected in sequence;
[0009] The bottom edge of the release paper is aligned with the bottom edge of the foam base layer, the top edge of the release paper is wavy, the lowest point of the wavy release paper is higher than the top edge of the foam base layer, and the width of the foam base layer is flush with the width of the adhesive layer.
[0010] As a preferred embodiment of wavy edge foam tape, the foam base has a thickness of 0.5 mm. The 0.5 mm foam base is used to absorb and disperse impact forces, protecting the items inside the carton.
[0011] As a preferred embodiment of wavy edge foam tape, the adhesive layer is made of acrylic, and the acrylic adhesive layer is used to firmly bond the various sides of the carton together.
[0012] As a preferred embodiment of wavy edge foam tape, the foam base layer is yellow, which makes the tape body visually striking and easy for workers to identify by color.
[0013] As a preferred embodiment of wavy-edged foam tape, the release paper is white. The white release paper serves as an isolation layer, effectively preventing the adhesive side of the tape body from accidentally sticking to other objects.
[0014] As a preferred option for wavy edge foam tape, the foam base layer is made of PE material, which effectively absorbs and disperses external forces due to its good elasticity and cushioning ability.
[0015] As a preferred embodiment of wavy edge foam tape, it also includes a roll, wherein the tape body is wound in an orderly manner around the outer circumference of the roll, and the roll is used to prevent the tape body from becoming tangled or knotted during storage.
[0016] As a preferred embodiment of wavy edge foam tape, the width of the roll is flush with the width of the foam base layer, and the width of the roll is less than the minimum wavy width of the release paper.
[0017] As a preferred embodiment of a wavy edge foam tape, the outer circumferential surface of the roll is provided with an anti-adhesion layer, which is used to prevent the tape body from sticking to the roll.
[0018] As a preferred embodiment of wavy edge foam tape, the anti-adhesion layer is made of PE material, which reduces the possibility of the tape sticking to the roll.
[0019] The beneficial effects of this invention are as follows: By setting the top edge of the release paper to a wavy shape, users can easily pinch the release paper along the wavy edge and peel it off from the foam base and adhesive layer when tape is needed. The wavy edge provides a clear point of leverage, making it easier to grip and apply force with fingers compared to traditional straight-edged release paper, making the release paper peeling operation more convenient and faster, greatly improving efficiency. Moreover, the lowest point of the wavy shape is higher than the top edge of the foam base, ensuring that during the peeling process, the release paper will not be overly adhered to the foam base or adhesive layer, preventing tearing of the foam base or affecting the adhesive layer's stickiness, thus ensuring the integrity and good performance of the tape body before use. The bottom edge of the release paper aligns with the bottom edge of the foam base, and the width of the foam base is flush with the width of the adhesive layer. This design ensures good integrity and consistency of the tape body at all levels. The wavy shape of the top edge of the release paper adds a unique visual effect, making it more recognizable among many ordinary tapes. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.
[0032] In one embodiment of this utility model, such as Figure 1-6 As shown, a wavy edge foam tape is provided, including: tape body 1, including release paper a, foam base layer b and adhesive layer c connected in sequence; the bottom edge of release paper a is aligned with the bottom edge of foam base layer b, the top edge of release paper a is wavy, the lowest point of the wavy shape of release paper a is higher than the top edge of foam base layer b, and the width of foam base layer b is flush with the width of adhesive layer c.
[0033] This utility model provides a wavy-edged foam tape. By setting the top edge of the release liner a to a wavy shape, when the tape is needed, the user can easily pinch the release liner a along the wavy edge and peel it off from the foam base layer b and the adhesive layer c. The wavy edge provides a clear point of force, making it easier to grip and apply force with fingers compared to the traditional straight-edged release liner a, making the peeling operation more convenient and faster, greatly improving efficiency. Moreover, the lowest point of the wavy shape is higher than the top edge of the foam base layer b, which ensures that during the peeling process, the release liner a will not be overly adhered to the foam base layer b or the adhesive layer c, thus preventing the foam base layer b from being pulled or affecting the adhesiveness of the adhesive layer c, ensuring the integrity and good performance of the tape body before use. The bottom edge of the release liner a is aligned with the bottom edge of the foam base layer b, and the width of the foam base layer b is flush with the width of the adhesive layer c. This design ensures that the tape body 1 maintains good integrity and consistency at all levels. The wavy shape on the top edge of the release liner adds a unique visual effect, making it more recognizable among many ordinary tapes.
[0034] Preferably, the thickness of the release paper a is 0.03-0.1 mm, which ensures that it is easy to peel off without being too thick.
[0035] Preferably, the thickness of the adhesive layer c is about 0.01-0.05 mm to ensure sufficient adhesion and to prevent glue overflow after bonding due to excessive glue amount.
[0036] Preferably, the foam base has a thickness of 0.5 mm. The 0.5 mm foam base is used to absorb and disperse impact force, protecting the items inside the carton.
[0037] Preferably, adhesive layer c is made of acrylic acid, which is used to firmly bond the various surfaces of the carton together. Acrylic acid, as the material of adhesive layer c, has excellent adhesion. It can form a strong bond on different material surfaces, such as the paper surface of the carton. Acrylic adhesive layer c also has good weather resistance, maintaining good adhesion under different environmental conditions, such as temperature and humidity changes. For the carton, regardless of environmental changes encountered during storage or the bumps and climate changes during transportation, acrylic adhesive layer c can ensure the firm bonding of all surfaces of the carton.
[0038] Preferably, the foam base layer b is made of PE material. PE foam base layer b, with its excellent elasticity and cushioning ability, effectively absorbs and disperses these external forces. When external forces such as impact or compression are applied to the foam tape, the PE will compress and deform appropriately to buffer and transform the force, preventing it from directly acting on the protected item.
[0039] For example, in the context of electronic product packaging, when precision electronic products such as mobile phones and tablets are subjected to bumps and collisions during transportation, the PE foam base layer b can absorb vibration energy through elastic deformation, preventing internal components from being damaged by hard impacts.
[0040] PE is chemically stable and does not readily react with most substances. Whether exposed to humid air, weak acids or alkalis, or within a certain temperature fluctuation range, it maintains its structural and performance stability. In outdoor equipment transportation and warehousing scenarios, where it may face rain erosion and large temperature differences between day and night, the PE foam base layer remains reliable and durable, without easily aging or degrading. This ensures consistent cushioning and protection of the tape, extends the tape's lifespan, and reduces the cost of frequent packaging material replacements.
[0041] Preferably, the foam base layer b is yellow. The yellow foam base layer b makes the tape body 1 eye-catching in appearance, making it easy for staff to identify by color.
[0042] In real-world applications, such as in logistics warehouses and production workshops, there are often a large number of different types of items and materials. Workers need to quickly and accurately identify the required tools or materials. This yellow foam base layer (b) plays a crucial role in this identification process, allowing workers to quickly locate the desired item, significantly improving work efficiency and reducing the time spent searching for tools or materials.
[0043] When there are many similar foam tape products on the market, users can more easily and accurately select the product again in subsequent purchases or uses by relying on their memory of the yellow foam base layer b after using it once. This helps to improve the product's market recognition and user repurchase rate.
[0044] Preferably, the release paper a is white. The white release paper a serves as a separator, effectively preventing the adhesive surface of the tape body 1 from accidentally sticking to other objects.
[0045] In warehouse storage scenarios, when tape rolls are stacked, without release paper (a) to separate them, the adhesive layers (c) of adjacent rolls will press and contact each other, quickly sticking together, making it difficult to retrieve and even damaging the entire roll. White release paper (a) effectively avoids this situation, ensuring that each roll of tape remains independent and intact during storage.
[0046] During long-distance transportation and frequent loading and unloading, the environment is complex and changeable. White release paper prevents tape from accidentally sticking to packaging boxes, pallets, and other goods, avoiding uneven tape tearing and damage to packaging materials during unloading, and ensuring that goods can be efficiently and undamagedly transferred to their destination.
[0047] The wavy-edged foam tape also includes a roll 2. The tape body 1 is wound in an orderly manner around the outer circumference of the roll 2. The roll 2 is used to prevent the tape body 1 from becoming tangled or knotted during storage. As a stable support structure, the roll 2 can effectively limit the movement range of the tape, ensuring that it is always wound on the roll 2 in a predetermined manner, thereby completely eliminating the occurrence of tangling.
[0048] Specifically, the width of roll 2 is flush with the width of foam base layer b, and the width of roll 2 is less than the minimum wavy width of release paper a.
[0049] When the width of roll 2 is the same as that of the tape, the tape is wound more neatly on roll 2, and there will be no accumulation or gaps of tape at the edge of roll 2 due to the difference in width. This helps to maintain the stability of the tape during storage and use and avoid damage to the foam base layer b and the adhesive layer c.
[0050] When the width of roll 2 is less than the minimum wavy width of release paper a, during storage, release paper a can completely cover the foam base layer b and adhesive layer c without being disturbed by roll 2, maintaining its good isolation and easy-to-peel properties, ensuring that when the user needs to use the tape, they can easily pinch the release paper a along the wavy edge and peel it off, thus enabling the normal use of the tape.
[0051] Specifically, the outer circumferential surface of the roll 2 is provided with an anti-stick layer d, which is used to prevent the tape body 1 from sticking to the roll 2. Since the tape body 1 has an adhesive layer, during storage, without effective protective measures, the tape is likely to come into direct contact with the outer circumferential surface of the roll 2 and stick. Once sticking occurs, it will have many adverse effects. For example, when the tape needs to be used, it will be difficult to pull the tape smoothly from the roll 2, which may require extra time and effort to tear, and may even cause the tape to break, deform, or be damaged during the extraction process.
[0052] The anti-stick layer d can effectively reduce the affinity between the adhesive layer of the tape and the surface of the roll 2, so that the adhesive of the tape cannot adhere to the roll 2, thereby preventing the two from sticking together.
[0053] Specifically, the anti-adhesive layer d is made of PE material, which reduces the possibility of the tape sticking to the roll 2. PE material has excellent chemical stability and does not easily react with the chemical components such as adhesives and binders used in the tape adhesive layer c. Most tapes may contain acrylates or rubber-based adhesives, but PE, under normal temperature and storage conditions, cannot chemically react with these substances to form new sticky substances. This ensures that the tape and roll 2 are firmly bonded together, effectively maintaining their original independent state.
[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
