This paper aims to design a safe cushioning package for eggs express delivery, which is suitable for small batch and multi-batch transportation. In order to verify the cushioning effect of packages, the area and thickness of cushion pads were calculated by the classical six-step cushioning packaging method, and the stretching cushioning structure was made. The strength of packages was checked by the formula, and the drop and random vibration tests of packages were carried out according to ISTA 3A standard. The results of 3 groups of repeated tests on different falling faces, edges and angles of 5 boxes of eggs showed that the breakage rate was much lower than the 10% breakage rate of cushioning packages on the market, which had good protection effect. Random vibration test showed that there were no eggs in cushioning packages. Finally, it is concluded that the safe express packaging of eggs designed in this paper has good cushioning performance, can ensure that eggs are effectively protected under the transportation of express logistics. It has good application prospects.
