This paper studies the carrying capacity and cushioning performance of multi- layer corrugated pallets with different structures to improve their cushioning performance. The bending resistance, compressive strength and cushioning performance of different structures of multi-layer corrugated pallets were analyzed by means of bending test, pressure test and compression test. The results show that multi- layer corrugated fiberboards have the maximum bending resistance when the corrugation is in parallel direction and the fiberboards are in longitudinal lamination, which is consistent with the linear relation between the maximum bending resistance and layer numbers. Vertical compressive strength of multi-layer corrugated fiberboards was greater than parallel compressive strength, which was greater than plane compressive strength, and vertical compressive strength and parallel compressive strength increased with the increase of layers, but plane compressive strength decreased. Vertical carrying capacity of foot piers was high, but their cushioning performance was unsatisfactory. Multi- layer corrugated fiberboards and EVA foam were combined to improve the cushioning performance. When the EVA foam accounted for 3/5 and the multi-layer corrugated fiberboard accounted for 2/5 of the total thickness of a foot pier, the cushioning efficiency and compressive strength of feet piers reached optimal. This paper may provide references for production of multi-layer corrugated pallets.
