Pallets are the medium to transform static goods into dynamic goods, a loading platform, and a moving platform, or a movable ground. Even if the goods on the ground lose their flexibility, once they are loaded on the pallet, they immediately acquire mobility and become flexible mobile goods, because the goods on the pallet are ready to move into motion at any time. This dynamic loading and unloading method, which is composed of pallets as basic tools, is called pallet operation.

Pallet operation can not only significantly improve the loading and unloading effect, but also change the form of warehouse buildings, the structure of ships, the loading and unloading facilities of Railways and other modes of transportation and the management organization. In the aspect of goods packaging, it promotes the standardization and modularization of packaging, and even has a significant impact on the general mode of production activities other than loading and unloading. With the production equipment becoming more and more sophisticated, the automation level getting higher and higher, the production planning and management methods becoming more and more advanced, the work of handling between processes and supplying materials and semi-finished products to the production line becomes more and more important.
