Wooden cases are widely used all over the country. In order to make the wooden case packing universal in the future application, it is best to choose the international size to facilitate the communication and application of wooden cases in the future. Of course, it is understandable that different industries have different requirements for the standard size of wooden cases because they have formed their own inherent packaging size for a long time. However, in the long run, we should still choose the national standard size. This also lays the foundation for wooden cases to meet international demand. Whether it is the international size or the inherent wooden box size of the enterprise, its ultimate goal is to make the wooden box fully play its role. Among them, whether it is an enterprise that buys wooden boxes or an enterprise that makes wooden boxes, it is necessary to first consider the specifications and sizes of transportation tools and transportation equipment. The suitable size of wooden cases should just meet the size of the means of transport, which can improve the full and reasonable utilization of the space of means of transport and save the transportation cost, especially considering the box size of containers and transport trucks. In addition to considering the standard size, we should also consider the size of the warehouse and the size of each cargo hold; Think about the packaging standard of goods packed in wooden cases. According to the packaging standard of goods packed in wooden cases, choose wooden cases with appropriate size and make maximum use of them. The wooden box is composed of side faces, end faces, bottom and cover, which has the unique characteristics of moisture resistance, wear resistance, breakage resistance, good processability and easy recovery of combustible materials. Install the end face on the side first, and then install the bottom and cover on the side and end face. The maximum weight and the maximum external dimension of the contents in the frame are determined on the premise that vehicles are usually transported. Sliding wooden cases are packed in medium-sized wooden cases, and their contents are limited to 200- 1500_, the sum of their external dimensions is limited to 7m, and their width and height are below1.5m. They are mainly used for wooden cases of mechanical products and containers of small goods. The structural difference between the sliding wooden box and the wooden box is that the frame wooden box is outside and the skeleton is inside the box; When assembling the frame wooden case, first install two sides on the base and two sides, and finally bind the top cover; Both of them are based on the base, but the frame wooden box has more frame structures at the end and side than the sliding wooden box. It is precisely because of these frame structures that the load that the frame wooden box can bear is much more important than the sliding wooden box.
