【摘要】 采用模压成型法制备了一种新型的可生物降解的缓冲包装材料,并通过正交试验研究了原材料配比对材料表观密度的影响,获得了主要的影响因素和各组分的最优配比。试验结果表明,马铃薯淀粉与纤维的质量比为5∶1,PVC含量为45g,增塑剂甘油含量为50g,AC发泡剂含量为0.70g时,淀粉/纤维缓冲包装材料的表观密度最大。最后对材料的缓冲性能和泡孔结构进行了研究,并就其缓冲性能与传统的塑料缓冲包装材料进行了比较。更多还原

【Abstract】 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.更多还原
