Combining the visco-elastic plasticity and the compression damage mechanism of honeycomb paperboard and corrugated paperboard, the strain-stress curve and cushioning-coefficient curves were acquired and the static constitutive relation of honeycomb paperboard and the superposed paperboard was established based on results of static compression test, and the cushion performance curve was analyzed. The result showed the cushion performance of honeycomb superposed corrugated paperboard is better than honeycomb paperboard. The purpose was to provide reference for the optimal design of packaging system using honeycomb paperboard as cushion material.
