Structural elements of paper tray products
1. The design of the structural elements of cushioning packaging is the basis of the structural design of paper tray products. At present, the design of structural elements of paper tray products in China is still in the preliminary design stage. The basic structural elements of paper tray products usually include wave, table shape, and hemisphere. The more common ones are the wave shape and the table shape. In the actual design, most of them are combined with a series of stiffener settings to improve the performance of all aspects of the elements, so as to obtain a good cushioning effect and adapt to the packaging requirements of different products. The performance of the structural elements is mainly reflected by the carrying capacity, impact energy absorption and resilience
1. Carrying capacity
With different paper tray cushioning packaging structures, the static load and deformation are different. General research and tests have proved that it is ideal to cushion the load-deformation of the static test of the structural elements of the packaging. The force on the contents of the package is not increasing, and the capacity is completely absorbed by the paper tray. Tests have proved that 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 over Small, it will affect the release of the paper tray.
2. Absorption of energy
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.
3. Resilience
The paper tray is restored to its original size after loading, which is very important for the structure of the paper tray. For a paper tray designed with a good structure, it has a great advantage in resilience. The better the protection, therefore, we must ask the designer to consider all aspects of the structure, craftsmanship, etc. in the design process at the initial stage of the product.
