A new degradable starch/fiber cushioning packaging material was prepared by compression molding. The influence of mixture ratios of raw materials on apparent density of the new material was studied through orthogonal experiments. The main influencing factors and optimal mixture ratios were obtained. The results showed that the starch/fiber cushioning packaging material has the maximum apparent density under the operating conditions of the ratio of potato starch and fiber 5∶1, PVA 45 g, glycerol 50 g and AC foaming Agent 0.70 g. The cushioning property and cell structure were studied. The cushioning property of the new material was compared with that of the conventional plastic cushioning packaging material.
