Dangerous goods are goods with dangerous characteristics. Improper handling during transportation and storage will cause certain harm to people, animals, environment and property. Therefore, great changes have taken place in the transportation of dangerous goods, including protective packaging regulations. The packaging of dangerous goods mainly focuses on the details of materials and structures.

The packaging scheme must pass the performance evaluation. There are drop tests, top load tests, and other similar methods. Therefore, if the package of very dangerous goods passes the drop test at the height of 1.8m, it is a highly dangerous material, which is called class I package; If it is a medium-sized dangerous goods package, it shall pass the drop test with a height of 1.2m. If the packing box is used for the packing preparation of explosives, special tests of explosives shall also be carried out to judge whether it is a secondary packing; If it is a package of slightly dangerous goods, it shall pass the 0.8m drop test, which is called class III package.

There are also some concepts about the packaging of dangerous goods. Including inner packaging, outer packaging, combined packaging, composite packaging, etc. The inner packaging is the surface packaging of goods during transportation, while the outer packaging is the exterior of composite packaging or combined packaging to protect product adsorption materials and other components required to maintain the gas content. Combined packaging is a packaging combination for the purpose of transportation, so that one or more inner packaging can be fixed together and synthesized, and then packaged in the outer packaging. The composite packaging has only one outer packaging and one containing gas. In addition, it forms a complete package structurally and will always be a whole in storage and transportation after combination.
