Why is the appearance and development of containers a revolution in packaging and transportation?

Containers and pallets are used more and more, and the international composite transportation centered on container transportation in developed countries has accounted for 80% of the total transportation packaging, which greatly facilitates the packaging of scattered groceries. Using revolving containers to load groceries, and using corrugated boxes and pallets for preliminary packaging, can be stored and kept conveniently to avoid damage to goods. Moreover, when large containers and pallets are used for transit, the goods in the box do not need to be inverted or reloaded, and they are transported as a whole in the logistics process, which can limit and prevent the damage of goods and improve the transit efficiency. In terms of loading and unloading, for short-distance transportation and distribution, about two-thirds of the time is spent on loading and unloading of scattered goods, so it is particularly important to improve the efficiency of loading and unloading of scattered goods and reduce logistics costs. With the improvement of the overall level of logistics facilities, forklifts, cranes and other machinery are mostly used for loading and unloading of transportation packages, avoiding the damage caused by manual rough loading and unloading; Mechanized loading and unloading and handling of forklifts and cranes create conditions for the large-scale and integration of transport packaging containers. The generalization of forklift and crane machinery in the process of loading and unloading and handling also promotes the standardization of large containers and pallets. Therefore, the use of large containers and pallets to package products is conducive to the realization of civilized loading and unloading services, mechanized loading and unloading, standardized operation and scientific management; At the same time, the use of large or integrated containers and pallets for transportation also facilitates the loading and unloading of mechanical forklifts, which is conducive to shortening the loading and unloading time, thus reducing the logistics cost. In warehouse management, containers and pallets can be neatly stacked and managed as a whole. With more and more kinds of containers, such as heat preservation containers, ventilation containers and other functional containers, it is possible to manage a large container as a warehouse. It does not need a traditional warehouse, and in the process of logistics, it saves a series of warehousing operations such as warehousing, acceptance, counting, palletizing, storage and delivery, which reduces the requirements of products for warehouses and makes the on-site management of products easier to realize. In addition, when containers and pallets are used as storage units to store goods in the warehouse, the stacking height can be increased, the storage density can be improved, the capacity utilization rate of the warehouse can be improved, and the automation of stacking in high-rise goods warehouses can be realized, thus reducing the logistics cost. When containers are used as storage units, mechanical building separation can be adopted to improve the mechanization level of cargo building separation.
