Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging paperboard technology, specifically to a UV-resistant composite honeycomb packaging paperboard. Background Technology
[0002] In existing traditional packaging cardboard designs, to meet diverse packaging needs, a single material or a simple composite structure is often used to accomplish the task. While this design concept has a certain application basis in long-term practice, in-depth analysis has revealed that this method has significant shortcomings in terms of practicality.
[0003] Specifically, traditional packaging cardboard often falls short in terms of both strength and UV protection. Regarding strength, due to its simple material composition or composite structure, cardboard is prone to deformation and breakage when subjected to external pressure or impacts, compromising the safety of packaged goods during transportation. Similarly, traditional cardboard performs poorly in UV protection, directly impacting the lifespan of packaged goods in direct sunlight or environments with strong UV radiation.
[0004] Therefore, in order to overcome the shortcomings of traditional packaging paperboard in terms of practicality, it is necessary to improve and innovate existing designs. By adopting new materials and optimizing composite structures, the strength, UV resistance, moisture resistance, and oil resistance of packaging paperboard can be improved to meet packaging needs in different environments. Utility Model Content
[0005] The purpose of this invention is to provide a UV-resistant composite honeycomb packaging paperboard to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a UV-resistant composite honeycomb packaging paperboard, comprising...
[0007] The cardboard body has a honeycomb board layer in the center, and a base layer one and a base layer two are respectively provided on both sides of the honeycomb board layer. A decorative panel layer and a protective inner panel layer are respectively provided on the outer side of the base layer one and the base layer two. A waterproof outer layer and a waterproof inner layer are respectively provided on the outer side of the decorative panel layer and the protective inner panel layer.
[0008] The honeycomb panel layer includes a cardboard frame and a honeycomb core disposed inside the cardboard frame, and the honeycomb core is uniformly provided with honeycomb holes, and each honeycomb hole is provided with foam particles.
[0009] The inner protective plate layer is uniformly filled with nano-titanium dioxide particles.
[0010] Furthermore, the inner side of the cardboard layer frame is provided with a cavity groove for accommodating the honeycomb core, and the inner contour of the cavity groove matches the outer contour of the honeycomb core to ensure structural stability.
[0011] Furthermore, adhesive layer one and adhesive layer two are respectively provided at the connection between substrate layer one and substrate layer two and the honeycomb panel layer to enhance the firmness of the interlayer connection.
[0012] Furthermore, the shape of the foam particles matches the shape of the honeycomb holes to ensure filling effect and structural integrity.
[0013] Furthermore, the size of the nano-titanium dioxide particles is less than 100 nanometers, thereby providing highly efficient ultraviolet blocking performance.
[0014] Furthermore, the waterproof outer layer and waterproof inner layer are made of waterproof materials, and both the waterproof outer layer and waterproof inner layer are sprayed onto the outside of the decorative panel layer and the protective inner board layer, which can effectively block water penetration and ensure the dryness and durability of the cardboard.
[0015] This utility model provides a UV-resistant composite honeycomb packaging paperboard, which has the following significant advantages and positive effects compared with the prior art:
[0016] Firstly, this invention employs a multi-layered structural design. The inner layer uses a material with UV protection, while the outer layer is a high-strength honeycomb structure. This innovative technical solution not only effectively ensures the strength of the cardboard but also successfully achieves UV protection. This structural design allows the inner and outer layers to work together. The outer honeycomb structure effectively protects the inner UV-protective layer, preventing damage to the packaging cardboard from collisions during transportation and storage. This ensures the protective effect of the inner UV-protective layer and improves the overall protective performance of the packaging cardboard.
[0017] Secondly, this invention incorporates foam particles between the honeycomb structures to form a cushioning structure. This design increases the rigidity of the board while significantly improving softness and cushioning effect by utilizing the columnar foam particles within the cushioning layer. In practical applications, this cushioning structure effectively mitigates and disperses impact forces, helping to extend the service life of the cardboard. Furthermore, it provides superior cushioning protection for packaged goods, ensuring their safety during transportation, while maintaining the lightweight and low-cost nature of the cardboard, meeting the demands of modern logistics for packaging materials.
[0018] Furthermore, this invention adds a waterproof coating to the surface and inside of the cardboard, achieving multi-functional integration of moisture resistance and oil resistance. This improvement significantly broadens the application range of packaging cardboard, making it suitable not only for packaging general goods but also for food, pharmaceuticals, and other applications requiring special moisture and oil resistance. This multi-functional integrated design greatly enhances the practicality and market competitiveness of packaging cardboard.
[0019] In summary, this utility model has significant advantages and positive effects in solving the problems existing in the prior art, and has made important contributions to the development of the packaging industry. Attached Figure Description
