目的 对运输包装的案例进行分析，使得运输包装的优化设计能达到增强保护性，降低包装综合成本的效果。方法 在收集大量运输包装设计案例的基础上，通过对新旧方案的分析比较，归纳总结出结构、材料、尺寸等优化方法，全面覆盖了运输包装优化设计的各个方面。结果 根据企业实际案例，提供了不同的优化参数，如产品体积减小了34%，角跌落和面跌落G值减小，单件包装材料成本降低，产品的集合装载率提高了46%等。结论 提出“三步走”的运输包装优化设计方法，最终实现了减量、减容、减费、增效的目的，从而降低了包装的综合成本。

The work aims to analyze the transport package cases so as to enhance protection and reduce the comprehensive cost of package. Based on the collection of numerous transport design cases, original and improved schemes were compared and the methods of structure optimization, material optimization, size optimization were summarized, covering all respects of transport optimal design. According to the actual case of enterprise, different optimization parameters were provided, such as product volume decreased by 34%, G value of corner drop decreased, cost of single package material reduced, product compact loading rate increased by 46% etc. In conclusion, three-step transport optimal design is put forward. It reduces quantity, volume and cost, improves efficiency and finally reduces the comprehensive cost.
