The paper tray is an ideal lining cushioning package. It is made by dewatering paper pulp in a net-shaped mold. It uses waste newspapers, carton paper, paper tubes, and pure wood pulp as the main raw materials. After pulping and mixing The slurry is mixed into a certain concentration of slurry by other processes, and is vacuum-adsorbed on a special mold to form a semi-finished product of wet green pulp. Then, it is dried and hot-pressed to form a variety of lining environmentally friendly packaging products, which are shock-proof, moisture-proof and waterproof Static electricity and other functions. So what are the elements of the paper support structure?
1, carrying capacity
Paper tray manufacturers use different paper tray packaging to cushion the structure, and the static load and deformation are different. Ideal to cushion the static test load deformation of packaging structural elements. The force on the contents of the package is not increasing, and the capacity is absorbed by the paper tray. Another important factor that affects the load-bearing capacity is the slope. From the perspective of a single load-bearing capacity, the smaller the slope of the side wall of the buffer structure, the higher the load-bearing capacity. However, considering the paper tray forming process, the slope is too small. Will affect the release of the paper tray.
2. Resilience
The paper tray package is restored to its original size after loading, which is very important for the structure of the paper tray package. For a paper tray designed with a good structure, it has great advantages in resilience. The protection of the product is better. Therefore, the paper tray manufacturer must ask the designer to consider the structure and technology in the design process at the initial stage of the product.
3, energy absorption
The paper tray can absorb external energy during the product circulation process to protect the product. The greater the absorbed energy, the better the buffering capacity. In addition, the degree of energy absorption is also related to the physical state of the paper tray, such as density, quality and deformation laws.
The above content is an introduction to the elements of the paper tray structure. A number of cavities with simple shapes and good dynamic cushioning performance are evenly distributed in the paper tray structure to play a role in buffering, stabilizing and improving strength. The problems of large-area cavity structure instability and strength reduction caused by the paper support structure can be solved by arranging multiple or symmetrical reinforcing ribs. In daily life, paper trays are often used around us, and its application range is very wide, which brings great convenience to our lives.
