In order to consider the effects of honeycomb cardboard on the cushion performance of foam packaging system, the paper analyzes the dynamic performance of foam packaging system based on the finite element code Abaqus/Explicit. The simulation results reveal that the foam layer plays the key role in the buffer system under low initial impact kinetic energy, however, when the initial impact kinetic energy reaches a relative large value, the foam layer is insufficient to reduce the impact velocity and the honeycomb cardboard will assume important responsibility in the whole buffer process. The honeycomb cardboard can reduce the peak acceleration of the impact object significantly and thus improve the cushion performance of the whole system. So it is necessary to take the honeycomb cardboard into consideration in the process of designing cushion packaging system to avoid excessive package.
