The most basic requirement of the pallet packaging is to ensure close contact with the packaged material. The design of the structural elements of the buffer packaging is the foundation of the structural design of the paper pallet packaging products. At present, the design of the structural elements of the paper pallet packaging products in China is still in the primary stage In the planning stage, the basic structural elements of paper tray packaging products generally include waveform, table shape and hemispherical shape, among which waveform and table shape are more common. Function in all aspects to obtain excellent cushioning effect and adapt to the packaging requirements of different products.
The function of the structural elements of the foundation is mainly represented by the bearing capacity, the absorption and resilience of impact energy:
bearing capacity
The static load and deformation of different paper tray packaging buffer structure methods are selected. General research and tests have proved that the load-deformation of the static test of the ideal buffer packaging structural elements. All the force on the items in the package is no longer added, so that it can be completely absorbed by the paper holder. Tests have shown that another key factor affecting the bearing capacity is the slope. From the perspective of a single bearing capacity, the smaller the slope of the sidewall of the buffer structure, the higher the bearing capacity, but from the perspective of the paper tray forming process, the slope is too small. , will affect the release of the paper tray.
2. Energy absorption
In the process of product circulation, the paper holder can absorb external energy to protect the product. The greater the absorbed energy, the better the buffering ability. The degree of other energy absorption is also related to the physical condition of the paper holder, such as density, quality and deformation rules. .
3. Resilience
The paper tray is restored to its original condition after loading. The structure of the paper tray is very important. The paper tray designed with excellent structure has great advantages in resilience. The better the protection of the product, therefore, at the initial stage of the product, we require planners to comprehensively consider the structure, process and other aspects in the planning process.
