According to some embodiments of the utility model, the packaging structure 100 is a foam piece. Wherein, the foam has light weight, environmental protection, low production cost and elasticity. Therefore, the weight, pollution and production cost of the packaging structure 100 can be reduced, and certain elastic deformation can be generated at the same time, so that the packaging structure 100 can buffer the external force extrusion generated in the loading, unloading and transporting processes, thereby reducing the influence of the external force on the packaged piece 200 in the groove, and improving the safety in the loading, unloading and transporting processes of the packaged piece 200. In addition, in the process of placing the packaged piece 200 in the groove, the groove can be pressed and deformed by pushing the packaged piece 200 so as to ensure that the groove can be tightly attached to the packaged piece 200, and the packaged piece 200 is prevented from shaking in the transportation process, so that the safety of the packaged piece 200 in the transportation process is further improved. In addition, the packaging structure 100 is also softer, and the damage to the packaged piece 200 caused by the excessively high hardness of the packaging structure 100 can be effectively prevented.
