Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a sealing structure of a pole roll protective film. Background Art

[0002] The pole roll is the basic material form of many high-tech products (such as semiconductor chips, precision electronic components, etc.), and its transportation process needs to be extremely cautious. The protective film is a thin film designed to protect the pole roll from the external environment (such as humidity, dust, etc.) during transportation and storage. The seal thickness refers to the thickness of the protective layer formed by this protective film on the surface of the pole roll, which directly determines the protective ability and stability of the protective film. The pole roll transportation process is a key link in the manufacturing process of many high-tech products. Its details and precision are directly related to the quality and performance of the final product.

[0003] However, in this complex and delicate process, the thickness of the protective film seal will have a certain impact on the water content of the product. Summary of the invention

[0004] The present application provides a sealing structure for an extreme roll protective film, which can reduce the thickness of the sealing structure, thereby achieving the effect of reducing the overall water vapor penetration of the protective film.

[0005] In a first aspect, the present application provides a sealing structure for a pole roll protective film, which is used to seal a protective film wrapped around a pole roll to be transported, wherein after the sealing structure seals the protective film, the overall water vapor penetration of the sealing structure and the protective film is M, and M is less than or equal to a first preset value;

[0006] The thickness of the sealing structure is T, the length of the sealing structure is L, the width of the sealing structure is W, and the effective packaging surface area of ​​the protective film is S;

[0007] Based on the fact that M is less than or equal to the first preset value, according to the formula M=ATLS / W, the thickness of the sealing structure is calculated to be T less than or equal to the second preset value;

[0008] Among them, after the material of the protective film and the package volume of the pole roll to be transported are determined, A is the performance constant of the corresponding material, L and S are quantitatively based on the package volume, and the water vapor penetration amount M is changed by adjusting the thickness T of the sealing structure.

[0009] As an indispensable component in the electronics, energy and other industries, the safety and stability of the polar coil during transportation is directly related to the final quality of the product. The sealing structure of the protective film is even more important.

[0010] The sealing structure of the present application not only undertakes the task of sealing the protective film behind the pole roll to be transported, but also ensures that the pole roll is protected from water vapor during long-distance travel or long-term storage with its excellent water vapor penetration performance. According to empirical research data in the industry, when the sealing structure and the protective film work together to form a protective layer, the overall water vapor penetration M can be controlled within the first preset value as needed, and this value is often much lower than the industry standard.

[0011] There is a certain relationship between the physical parameters of the seal structure and its water vapor protection ability. The four key indicators of the seal structure thickness T, length L, width W and the effective packaging surface area S of the protective film together constitute the basic framework of its performance. In particular, when the material of the protective film and the packaging volume of the polar roll to be transported are determined, the value of the performance constant A is determined. The A value is a manifestation of the inherent properties of the material.

[0012] Based on the above theoretical framework, it is not difficult to derive the formula M = ATLS / W. This formula is like a precise navigator, leading us to explore the mystery of how to affect the water vapor penetration M by adjusting the thickness T of the sealing structure. Specifically, when other conditions remain unchanged, there is a positive correlation between the thickness T of the sealing structure and the water vapor penetration M. This means that by reducing the thickness T of the sealing structure, we can effectively reduce the overall water vapor penetration M of the protective film, thereby providing a drier and safer transportation environment for the extreme roll.

[0013] In some examples, the thickness T of the sealing structure is: (0.2t1+t2+t3)*2≤T≤(t1+t2+t3)*2.2;

[0014] The protective film comprises a protective layer, an isolation layer and an adhesive layer. The total thickness of the protective film is t, the thickness of the protective layer is t1, the thickness of the isolation layer is t2, and the thickness of the adhesive layer is t3.

[0015] In some examples, when the thickness of the protective film is 200 mm, the thickness of the sealing structure is one of 395 mm, 362 mm, 219 mm, 210 mm, and 165 mm; or,

[0016] When the thickness of the protective film is 152 mm, the thickness of the sealing structure is one of 357 mm, 202 mm, 172 mm, and 88 mm;

[0017] When the thickness of the protective film is 133 mm, the thickness of the sealing structure is one of 164 mm, 156 mm, 126 mm, 111 mm, and 81 mm.

[0018] There is a complex and precise relationship between the thickness of each layer of the protective film. Specifically, the thickness T of the sealing structure, a key parameter, is not only directly related to the overall performance and stability of the product, but also affects its performance in practical applications. According to the given formula: (0.2t1+t2+t3)*2≤T≤(t1+t2+t3)*2.2, it can be clearly seen that the thickness T of the sealing structure is jointly determined by the thickness of each layer of the protective film (i.e., protective layer t1, isolation layer t2, adhesive layer t3), and this relationship presents a state of dynamic balance.

[0019] Each layer of the protective film has a corresponding structure and function. Among them, the protective layer is the first line of defense that is directly in contact with the external environment. Its thickness t1 not only determines the wear resistance and corrosion resistance of the product, but also affects the overall aesthetics. The isolation layer t2 effectively separates the protective layer from the adhesive layer to prevent adverse interactions between the two and ensure the long-term stability of the sealing structure. The adhesive layer t3 is the key to achieving a firm bond of the sealing structure, and its thickness is closely related to the bonding force and sealing performance.

[0020] When the thickness of the protective film is 200mm, the thickness of the sealing structure may show various changes, such as 395mm, 362mm, 219mm, 210mm, 165mm, etc. These different thickness values ​​actually reflect the different requirements and considerations for the performance of the sealing structure in different application scenarios. For example, in situations where higher strength and sealing are required, a thicker sealing structure may be selected; while in areas where there are strict restrictions on weight and space, a lighter and thinner design may be preferred.

[0021] When the thickness of the protective film is adjusted to 152mm or 133mm, the thickness of the seal structure will also change accordingly. These changes not only reflect the flexibility and diversity of design, but also deeply reveal the important role of material science and engineering technology in product design and manufacturing. By precisely controlling the thickness and ratio of each layer of material, the performance of the seal structure can be precisely controlled and optimized.

[0022] In some examples, the first preset value is less than or equal to 780 mm, and the second preset value is less than or equal to 400 mm.

[0023] In the field of maritime transportation, safety and efficiency are always the core goals pursued by the shipping industry. The first preset value and the second preset value are used to significantly reduce the amount of water vapor infiltration and optimize the thickness of the sealing structure, thereby creating a safe and efficient maritime transportation environment for the extreme volume.

[0024] The first preset value is usually set to be less than or equal to 780mm. This value is not set randomly, but is based on a large amount of empirical research and data analysis. It is directly related to the water vapor control level of the environment where the pole roll inside the seal is located. Excessive water vapor content may not only corrode the pole roll, but also affect the durability and effectiveness of the pole roll. Therefore, controlling the water vapor penetration below the first preset value is an important part of ensuring the safe transportation of pole rolls at sea.

[0025] The second preset value, the thickness T of the seal structure, is set to be less than or equal to 400mm. This setting also contains profound considerations. On the one hand, a thinner seal structure helps to reduce the weight of the overall package and improve navigation efficiency; on the other hand, the seal structure must also ensure sufficient strength and sealing to resist the damage to the pole roll caused by the impact of severe sea conditions on the ship and prevent seawater penetration.

[0026] In some examples, the effective packaging surface area of ​​the protective film is S, which includes other surfaces of the protective film corresponding to the packaging volume except the contact placement surface.

[0027] Specifically, the effective packaging surface area S refers to the area covered and effectively protected by the protective film. The calculation method of this area covers all surfaces of the corresponding packaging volume of the protective film, but excludes the part that is in direct contact with the placement surface. Compared with traditional packaging methods, this design strategy not only greatly reduces unnecessary material consumption, but also reduces production costs.

[0028] In some examples, the sealing structure also includes at least one isolation rib, which is disposed at the edge of the sealing structure, or the isolation rib is disposed on both sides of the sealing structure to seal the area of ​​the protective film to be sealed, and the isolation rib is used to enhance the sealing performance of the sealing structure.

[0029] As a crucial process, packaging technology is not only related to product safety and protection, but also directly affects product performance and life. Isolation ribs are a reinforcing component located at the edge or specific position of the sealing structure, and their role is far more than simple separation. During the packaging process, isolation ribs are set on both sides of the area to be sealed by the protective film, effectively preventing the mutual penetration of external impurities and internal substances. This design not only improves the tightness of the seal, but also greatly enhances the stability and durability of the overall structure.

[0030] In order to more intuitively demonstrate the role of isolation ribs, some actual cases can be introduced. In the field of food packaging, the use of a sealing structure with isolation ribs can effectively isolate air and moisture and extend the shelf life of food. The protection of the polar coil can also refer to the setting to improve the containment effect of the polar coil.

[0031] From a technical perspective, the design of the isolation bar also incorporates many scientific principles and engineering wisdom. The shape, size and material selection must be carefully calculated and verified experimentally to ensure that it can meet the strength requirements and perfectly integrate with the overall structure.

[0032] In some examples, the sealing structure further includes at least one reinforcing rib, which is disposed at an edge or inside of the sealing structure, and is used to enhance the overall strength of the sealing structure.

[0033] Ribs are reinforcing elements that are integrated into the edge or interior of a package structure. These elements, whether made of the same material as the main body of the package structure or made of a different material for specific performance requirements, are designed to provide additional support and protection for the entire package structure through their unique shape and size design. This design concept stems from a deep understanding and clever use of the mechanical properties of materials.

[0034] In practical applications, the design of reinforcement ribs often needs to be comprehensively considered based on multiple factors, such as the specific purpose of the packaging structure, the nature of the goods carried, and the expected transportation environment. For example, in the packaging design to protect precision electronic components, the reinforcement ribs may be designed as thin strips to maximize the structural strength with the minimum increase in mass; while in the packaging structure for transporting heavy mechanical parts, the reinforcement ribs may be more robust to ensure that the integrity of the packaging structure can be maintained under extreme transportation conditions.

[0035] In some examples, a side of the sealing structure close to the protective film is provided as a sealant layer.

[0036] The sealant layer has excellent adhesion and sealing properties, and can effectively block the penetration of water vapor and other harmful substances, thereby protecting the pole coil from damage. The thickness and material of the sealant layer need to be selected according to specific needs to ensure compatibility with the sealing structure and protective film.

[0037] In some examples, at least one of the material, thickness, number and position of sealing ribs, and number and position of reinforcing ribs of the sealing structure can be adjusted.

[0038] The sealing structure of the pole roll protective film of the present invention is designed with adjustable sealing strength. Considering the different requirements of pole roll protective films in different transportation environments, different degrees of sealing effects can be achieved to meet the needs of different transportation environments. This design makes the pole roll protective film more flexible and practical, and can adapt to a wider range of application scenarios.

[0039] In some examples, the sealing structures at least partially overlap, and an easily removable structure is provided at the overlapping position.

[0040] The overlapping characteristics of the seal structure are different from the traditional one-piece seal. This design achieves tight connection and stability in structure through carefully planned overlapping areas. This overlap is not a simple stacking, but a clever layout based on mechanical principles, which ensures that the seal is stable and does not fall off during transportation, and effectively prevents the goods from being accidentally opened or damaged during transportation. At the same time, the design of the overlapping part also takes into account the convenience of disassembly, and reserves space and possibilities for subsequent easy-to-disassemble structures.

[0041] The easy-to-remove structure overturns the traditional impression that seal removal requires professional tools or complicated operations. Users can easily separate the seal from the protective film through a few simple steps, such as gently pressing, rotating or pulling the preset easy-to-remove parts, without the assistance of any special tools or equipment.

[0042] In order to more clearly illustrate the technical solutions in the present application or the prior art, the drawings required for use in the examples or prior art descriptions will be briefly introduced below. Obviously, the drawings described below are only some examples of the present application. For those skilled in the art, other drawings can be obtained based on these drawings without paying any creative work.

[0043] Figure 1 This is a schematic structural diagram of the sealing structure of the pole roll protective film in an example of the present application. DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0045] To solve the above technical problems, please refer to Figure 1 As shown, the first aspect of the present application proposes a sealing structure for an extreme roll protective film, which can reduce the thickness of the sealing structure, thereby achieving the effect of reducing the overall water vapor penetration of the protective film.

[0046] Reference Figure 1 As shown, in some examples, the sealing structure of the pole roll protective film is used to seal the protective film after wrapping the pole roll to be transported, and after the sealing structure seals the protective film, the overall water vapor penetration of the sealing structure and the protective film is M, and M is less than or equal to a first preset value;

[0047] The thickness of the sealing structure is T, the length of the sealing structure is L, the width of the sealing structure is W, and the effective packaging surface area of ​​the protective film is S;

[0048] Based on the fact that M is less than or equal to the first preset value, according to the formula M=ATLS / W, the thickness of the sealing structure is calculated to be T less than or equal to the second preset value;

[0049] Among them, after the material of the protective film and the package volume of the pole roll to be transported are determined, A is the performance constant of the corresponding material, L and S are quantitatively based on the package volume, and the water vapor penetration amount M is changed by adjusting the thickness T of the sealing structure. The overall water vapor penetration amount M of the protective film is proportional to the thickness T of the sealing structure, and the overall water vapor penetration amount M of the protective film can be reduced by reducing the thickness T of the sealing structure.

[0050] As an indispensable component in the electronics, energy and other industries, the safety and stability of the polar coil during transportation is directly related to the final quality of the product. The sealing structure of the protective film is even more important.

[0051] The sealing structure of the present application not only undertakes the task of sealing the protective film behind the pole roll to be transported, but also ensures that the pole roll is protected from water vapor during long-distance travel or long-term storage with its excellent water vapor penetration performance. According to empirical research data in the industry, when the sealing structure and the protective film work together to form a protective layer, the overall water vapor penetration M can be controlled within the first preset value as needed, and this value is often much lower than the industry standard.

[0052] There is a certain relationship between the physical parameters of the seal structure and its water vapor protection ability. The four key indicators of the seal structure thickness T, length L, width W and the effective packaging surface area S of the protective film together constitute the basic framework of its performance. In particular, when the material of the protective film and the packaging volume of the polar roll to be transported are determined, the value of the performance constant A is determined. The A value is a manifestation of the inherent properties of the material.

[0053] Based on the above theoretical framework, it is not difficult to derive the formula M = ATLS / W. This formula is like a precise navigator, leading us to explore the mystery of how to affect the water vapor penetration M by adjusting the thickness T of the sealing structure. Specifically, when other conditions remain unchanged, there is a positive correlation between the thickness T of the sealing structure and the water vapor penetration M. This means that by reducing the thickness T of the sealing structure, we can effectively reduce the overall water vapor penetration M of the protective film, thereby providing a drier and safer transportation environment for the extreme roll.

[0054] It is worth noting that reducing the thickness of the seal structure is not unlimited. In actual operation, it is also necessary to consider multiple factors such as material strength, toughness, and processing costs. A seal structure that is both thin and tough can be more stable and reliable.

[0055] In summary, the sealing structure of the Jijuan protective film plays a role in transportation and storage with its unique design concept and excellent water vapor resistance. By deeply analyzing the relationship between its physical parameters and performance, and flexibly using the formula M = ATLS / W for optimized design, it is fully capable of creating a safe and efficient transportation environment for Jijuan.

[0056] Reference Figure 1 As shown, in some examples, the thickness T of the sealing structure is: (0.2t1+t2+t3)*2≤T≤(t1+t2+t3)*2.2;

[0057] The protective film comprises a protective layer, an isolation layer and an adhesive layer. The total thickness of the protective film is t, the thickness of the protective layer is t1, the thickness of the isolation layer is t2, and the thickness of the adhesive layer is t3.

[0065] In practical applications, the thickness of the seal structure is also affected by many factors, such as the physical properties of the material, processing technology, environmental conditions, etc. Therefore, in the design and manufacturing process, it is necessary to comprehensively consider various factors and verify and optimize the design through a large number of experiments and tests.

[0066] In some examples, the first preset value is less than or equal to 780 mm, and the second preset value is less than or equal to 400 mm.

[0067] In the field of maritime transportation, safety and efficiency are always the core goals pursued by the shipping industry. The first preset value and the second preset value are used to significantly reduce the amount of water vapor infiltration and optimize the thickness of the sealing structure, thereby creating a safe and efficient maritime transportation environment for the extreme volume.

It is directly related to the water vapor control level of the environment where the pole roll inside the seal is located. Excessive water vapor content may not only corrode the pole roll, but also affect the durability and effectiveness of the pole roll. Therefore, controlling the water vapor penetration below the first preset value is an important part of ensuring the safe transportation of pole rolls at sea.

[0069] The second preset value, the thickness T of the seal structure, is set to be less than or equal to 400mm. This setting also contains profound considerations. On the one hand, a thinner seal structure helps to reduce the weight of the overall package and improve navigation efficiency; on the other hand, the seal structure must also ensure sufficient strength and sealing to resist the damage to the pole roll caused by the impact of severe sea conditions on the ship and prevent seawater penetration.

[0070] In some examples, the effective packaging surface area of ​​the protective film is S, which includes the surface of the protective film corresponding to the packaging volume except the contact placement surface. This can reduce the consumption of unnecessary sealing structures.

[0071] Specifically, the effective packaging surface area S refers to the area covered and effectively protected by the protective film. The calculation method of this area covers all surfaces of the corresponding packaging volume of the protective film, but excludes the part that is in direct contact with the placement surface.

During the packaging process, isolation ribs are set on both sides of the area to be sealed by the protective film, effectively preventing the mutual penetration of external impurities and internal substances. This design not only improves the tightness of the seal, but also greatly enhances the stability and durability of the overall structure.

In the field of food packaging, the use of a sealing structure with isolation ribs can effectively isolate air and moisture and extend the shelf life of food. The protection of the polar coil can also refer to the setting to improve the containment effect of the polar coil.

[0075] From a technical perspective, the design of the isolation bar also incorporates many scientific principles and engineering wisdom. The shape, size and material selection must be carefully calculated and verified experimentally to ensure that it can meet the strength requirements and perfectly integrate with the overall structure.

[0076] In addition, it is worth noting that the addition of isolation ribs is not an isolated move. In the overall design of the sealing structure, its synergy with other components must also be considered. For example, in the design process, the compatibility and adhesion of isolation ribs with materials such as sealants and protective films must be fully considered to ensure that the overall performance of the sealing structure is optimized.

[0077] In some examples, the sealing structure further includes at least one reinforcing rib, which is disposed at the edge or inside of the sealing structure, and is used to enhance the overall strength of the sealing structure. The material of the reinforcing rib is the same as or different from that of the main body of the sealing structure, and its shape and size are designed according to actual needs to ensure that the pole coil can be effectively protected from external impact and extrusion during transportation and storage.

[0078] Ribs are reinforcing elements that are integrated into the edge or interior of a package structure. These elements, whether made of the same material as the main body of the package structure or made of a different material for specific performance requirements, are designed to provide additional support and protection for the entire package structure through their unique shape and size design. This design concept stems from a deep understanding and clever use of the mechanical properties of materials.

[0079] In practical applications, the design of reinforcement ribs often needs to be comprehensively considered based on multiple factors, such as the specific purpose of the packaging structure, the nature of the goods carried, and the expected transportation environment. For example, in the packaging design to protect precision electronic components, the reinforcement ribs may be designed as thin strips to maximize the structural strength with the minimum increase in mass; while in the packaging structure for transporting heavy mechanical parts, the reinforcement ribs may be more robust to ensure that the integrity of the packaging structure can be maintained under extreme transportation conditions.

[0080] In addition, the shape and size design of the reinforcement ribs must also fully consider their role in preventing external impact and extrusion. During transportation, goods are often exposed to vibration, collision and extrusion from all directions. The clever layout and reasonable design of the reinforcement ribs can effectively disperse the impact of these external forces on the packaging structure, thereby protecting the internal goods from damage. According to relevant empirical research data, under the same conditions, the deformation of the packaging structure equipped with reinforcement ribs when subjected to external impact is significantly lower than that of the packaging structure without reinforcement ribs, which fully proves the significant effect of reinforcement ribs in improving the overall strength of the packaging structure.

[0081] In addition to the above functions, the introduction of reinforcing ribs also brings other advantages. For example, in the manufacturing process of the packaging structure, the reinforcing ribs can be integrated as part of the mold, thereby simplifying the production process and reducing manufacturing costs. At the same time, the presence of reinforcing ribs also helps to improve the sealing and waterproof performance of the packaging structure, further ensuring the safety of the internal goods.

[0082] In some examples, a sealant layer is provided on one side of the seal structure close to the protective film. The sealant layer has excellent adhesion and sealing properties, and can effectively block the penetration of water vapor and other harmful substances, thereby protecting the pole coil from damage. The thickness and material of the sealant layer need to be selected according to specific needs to ensure compatibility with the seal structure and the protective film.

[0083] The adhesiveness of the sealant layer ensures that it fits tightly to the protective film without any gaps. This close contact not only enhances the overall structural strength, but also prevents the intrusion of tiny particles such as water vapor and dust. In the world of electronic devices, even the smallest impurities can cause serious malfunctions or damage. Therefore, the adhesiveness of the sealant layer is undoubtedly the first line of defense to protect the pole coil from damage.

[0084] By selecting materials with excellent sealing properties, the sealant layer can effectively block the penetration of water vapor, corrosive gases and other harmful substances. Once these harmful substances penetrate into the equipment, they will cause serious corrosion and damage to sensitive parts such as the pole coil. With the protection of the sealant layer, these potential risks are greatly reduced or even completely eliminated.

[0085] Of course, in order to give full play to the protective effect of the sealant layer, it is necessary to work hard on the selection of its thickness and material. Different application scenarios have different requirements for the sealant layer. Therefore, during the design process, engineers will carefully calculate and test according to specific needs to ensure that the selected sealant layer can meet the protection requirements without negatively affecting the overall performance of the product.

[0086] In some examples, at least one of the material, thickness, number and position of sealing ribs, and number and position of reinforcing ribs of the sealing structure can be adjusted. The sealing structure of the pole roll protective film of the present invention is designed to have an adjustable sealing strength. Considering the different requirements of pole roll protective films in different transportation environments, different degrees of sealing effects can be achieved to meet the needs of different transportation environments. This design makes the pole roll protective film more flexible and practical, and can adapt to a wider range of application scenarios.

[0087] The material selection of the sealing structure is one of the key factors that determine the sealing performance. Traditionally, manufacturers may rely on a single material to construct the sealing structure, but such an approach is often difficult to cope with complex and changeable transportation environments. The innovation of the present invention is that the material of its sealing structure can be flexibly adjusted according to specific needs. For example, in an environment with high humidity, a polymer material with excellent moisture-proof properties is used as a sealing material, which can effectively block moisture intrusion and protect the internal pole coil from corrosion. In an environment with large temperature changes, materials with better thermal stability can be selected to ensure that the sealing structure will not fail due to thermal expansion and contraction.

[0088] In addition to the choice of material, the thickness of the sealing structure also has a significant impact on the sealing effect. A thicker sealing structure can provide stronger pressure resistance and better sealing performance, but it may also increase material cost and weight. Therefore, the present invention allows the thickness of the sealing structure to be adjusted according to actual needs to achieve the best balance between performance and cost. For example, in transportation scenarios that need to withstand large mechanical shocks, the thickness of the sealing structure can be appropriately increased to improve its impact resistance; in scenarios where there are strict requirements on weight, the thickness can be reduced while maintaining sealing performance by optimizing the structural design.

[0089] In addition, the number and position of sealing ribs and reinforcing ribs are also important factors that affect the performance of the sealing structure. As a key component directly involved in the sealing process, the reasonable layout of the number and position of the sealing ribs can significantly improve the sealing effect. The reinforcing ribs are mainly used to enhance the overall strength and rigidity of the sealing structure to prevent deformation or rupture during transportation. The sealing structure design of the present invention fully considers these factors, allowing the user to adjust the number and position of sealing ribs and reinforcing ribs according to actual needs to achieve different degrees of sealing effects. For example, in scenarios where higher sealing requirements are required, the number of sealing ribs can be increased and their layout can be optimized; in scenarios where higher strength requirements are required, the number of reinforcing ribs can be increased to enhance the overall performance of the sealing structure.

[0090] This adjustable sealing structure design not only makes the polar roll protective film more flexible and practical, but also greatly broadens its application range. Whether it is protecting precision instruments in humid ocean transportation or ensuring the stable operation of electronic equipment under extreme temperature differences, the polar roll protective film of the present invention can show strong vitality with its excellent sealing performance and adaptability. At the same time, this design also reflects the modern industry's pursuit of product customization and personalization, allowing manufacturers to quickly adjust product configurations according to different customer needs and market environments to meet the diverse needs of the market.

[0091] In some examples, the seal structure at least partially overlaps, and an easily removable structure is provided at the overlapping position. The user can remove the seal structure from the protective film by simple operation without using special tools or equipment. This design not only improves the efficiency of transportation and storage, but also reduces the cost and complexity of maintenance.

[0092] The overlapping characteristics of the seal structure are different from the traditional one-piece seal. This design achieves tight connection and stability in structure through carefully planned overlapping areas. This overlap is not a simple stacking, but a clever layout based on mechanical principles, which ensures that the seal is stable and does not fall off during transportation, and effectively prevents the goods from being accidentally opened or damaged during transportation. At the same time, the design of the overlapping part also takes into account the convenience of disassembly, and reserves space and possibilities for subsequent easy-to-disassemble structures.

[0093] The easy-to-remove structure overturns the traditional impression that seal removal requires professional tools or complicated operations. Users can easily separate the seal from the protective film through a few simple steps, such as gently pressing, rotating or pulling the preset easy-to-remove parts, without the assistance of any special tools or equipment.

[0094] Furthermore, the design of this seal structure also brings about a significant improvement in transportation and storage efficiency. Since the seal removal becomes so simple and quick, logistics personnel can handle the warehousing, outbound and transshipment of goods more efficiently, reducing the time and labor costs consumed by removing the seal. At the same time, this design also reduces the risk of damage to goods during storage, because there is no need to frequently replace or adjust the seal position, thereby ensuring the integrity and safety of the goods packaging.

[0095] In addition, from the perspective of cost and maintenance, this seal structure also shows its unique advantages. On the one hand, due to the simplification and efficiency of the disassembly process, the seal damage and replacement requirements caused by improper operation are reduced, thereby reducing maintenance costs. On the other hand, this design also promotes the recycling of logistics packaging and the promotion of environmental protection concepts. Because the seal is easy to disassemble, the recycling and reuse of packaging materials is more convenient and efficient, reducing resource waste and environmental pollution.
