EPE and honeycomb paperboard combination, and EPS and honeycomb paperboard combination were taken as objects. Static compression test were carried out and the stress-strain curves and cushion coefficient curves of the three materials and two combinations were obtained. The result showed that the mechanical performance of combination structure is better; at the smaller stress, the combination structure presented the cushion performance of EPE and EPS respectively; and EPE and honeycomb paperboard combination is superior to EPS and honeycomb paperboard combination; in the intermediate stage of compression, the cushion performance curves of the two combination structures are basically identical, which are similar with the honeycomb paperboard; at the later larger stress stage, the combination structures still have some cushion ability. The combination structures combine the advantages of the two materials, and have better cushion performance under smaller or larger stress.
