Containers and pallets are two types of packaging containers that are increasingly used. In developed countries, the international composite transportation system centered on container transportation accounts for 80% of the total transportation packaging, which greatly facilitates scattered packaging. Packaging of groceries. When using a turnover container to load groceries, you only need to use corrugated boxes and pallets for initial packaging, which can be conveniently stored and kept to avoid damage to the goods. Moreover, when large containers and pallets are used for transshipment, the goods in the container do not need to be flipped or reloaded. They are transshipped as a whole during the logistics process, which can limit and prevent cargo damage and improve transshipment efficiency. In terms of loading, unloading and handling, for short-distance transportation and distribution, more than two-thirds of the time is spent on loading, unloading, and handling of scattered goods. Therefore, it is particularly important to improve the efficiency of loading, unloading, and handling of scattered goods and reduce logistics costs. With the improvement of the overall level of logistics facilities, forklifts, cranes and other mechanical loading and handling are mostly used for transportation and packaging, which avoids cargo damage caused by manual rough loading and unloading. The mechanized loading, unloading and handling of forklifts and cranes facilitate the large-scale and collection of transportation packaging containers. It has created conditions for the realization of industrialization, and the generalization of forklifts and cranes during loading, unloading and transportation has also promoted the standardization of large containers and pallets. Therefore, the use of large-scale containers and pallets for packaging products is conducive to the realization of civilized loading and unloading services, mechanization of loading and unloading, standardization of operations, and scientific management; at the same time, the use of large-scale or collective containers and pallets for transportation also facilitates mechanical forklift loading, unloading, and transportation. It is helpful to shorten loading, unloading and transportation time, thereby reducing logistics costs. In terms of warehouse management, the use of containers and pallets allows the containers or pallets to be neatly stacked and managed as a whole. As there are more and more types of containers, the emergence of functional containers such as insulated containers and ventilated containers makes it possible to manage a large container as a warehouse. It does not require a traditional warehouse. In the logistics process , which also eliminates the need for a series of storage operations such as warehousing, acceptance, counting, stacking, storage, and outbound storage, which reduces the requirements for products on the warehouse and makes the warehouse management of products easier to implement; in addition, the use of containers and pallets When storing goods as storage units in the warehouse, you can increase the storage stacking height, increase storage density, improve warehouse capacity utilization, realize the automation of high-rise cargo warehouse stacking, thereby reducing logistics costs. Using containers as storage units for counting, stacking, During processes such as warehouse transfer, mechanical sorting operations can be used to improve the mechanization level of cargo sorting.
