摘　　要：目的在设计快递包装时,应综合考虑瓦楞纸板和发泡聚乙烯(EPE)组合材料的缓冲作用,以达到减少缓冲材料用量的目的。方法以快递包装中常用的、不同厚度的EPE、三层瓦楞纸板、五层瓦楞纸板为研究对象,按照GB/T 8167—2008进行试验,得到EPE、三层瓦楞纸板/EPE、五层瓦楞纸板/EPE的最大加速度-静应力曲线,并进行拟合。结果EPE材料越厚,其缓冲性能越好;将EPE、三层瓦楞纸板/EPE、五层瓦楞纸板/EPE等3组数据的双曲线函数进行拟合,拟合度均大于95%,拟合效果较好;在同一静应力下,动态缓冲性能优劣顺序为五层瓦楞纸板/EPE>三层瓦楞纸板/EPE>EPE。结论拟合函数可用于快递包装设计,同时试验结果为快递包装减量化设计提供了依据。In the design of express packaging,the buffering effect of corrugated board and expanded polyethylene(EPE)composite materials should be considered comprehensively to reduce the amount of buffer materials.With EPE,three-layer corrugated board,and five-layer corrugated board commonly used in express packaging as the research object,the experiments were designed according to GB/T 8167—2008.The maximum acceleration-static stress curve of the materials were calculated and fitted.The results showed that the thicker the EPE material,the better its buffering performance.Three groups of materials of EPE,three-layer corrugated board/EPE,five-layer corrugated board/EPE were fitted with hyperbolic function,and the fitting degree was greater than 95%.The fitting effect was good.Under the same static stress,dynamic cushioning performance:five-layer corrugated board/EPE>three-layer corrugated board/EPE>EPE.The fitted function can be used for design of express packaging.The experiment result provides a basis for the reduction design of express packaging.
