Plastic pallets are indispensable products in the logistics industry, but the size of plastic pallets is related to the loading and unloading of goods. Therefore, the size of the cardboard is the basis for considering the size of other logistics equipment. When considering the multi-functionality of card sizes, the specifications of international standard cards should be appropriately supplemented to replace the exchange and use of cards. 2. Consider the packaging specifications of the goods to be loaded on the card. According to the packaging specifications of the goods to be loaded on the cardboard, select the appropriate cardboard. The extension line of the cardboard should be as short as possible, and the height of the center of gravity of the goods to be loaded should be controlled. The reasonable indicators for pallet loading are: 80% utilization rate of pallet size, and the height of the center of gravity of the goods exceeding two-thirds of the pallet width.

3.When considering the dimensions of transportation and transportation equipment, the appropriate card size should be that of the transportation vehicle, which can fully utilize the space of the transportation vehicle, increase the loading rate, and reduce transportation costs. Special attention should be paid to the dimensions of transportation containers and containers of commercial transportation vehicles. 4. Consider the size of the card for the usable area. Generally, for goods destined for Europe, 1210 cardboard or 1208 cardboard should be chosen. For products from Japan and South Korea, the 1111 pallets should be chosen. For Oceania, cardboard of 1140mm or 1067mm should be chosen. For goods destined for the United States, please choose 48-inch and 40-inch cards. In the United States, 1210 cards are usually used.
