摘　　要：以玉米交联淀粉和稻草秸秆纤维作为主料,聚乙烯醇(PVA)和羧甲基纤维素(CMC)作为复合增强剂,甘油作为增塑剂,采用单因素实验方法开发新型复合包装膜,确定成膜工艺参数和分析膜性能。实验结果表明,玉米交联淀粉的添加量为膜溶液的3.0%,聚乙烯醇(PVA)和羧甲基纤维素(CMC)添加量为膜溶液的3.0%,甘油添加量为膜溶液的3.0%,稻草秸秆纤维添加量为膜溶液1.0%,膜的性能最好。膜的拉伸强度19.67 MPa,断裂伸长率25.66%。Crosslinked corn starch and straw stalk fiber were used as main ingredients,Polyvinylalcohol （PVA）and carboxymethyl cellulose（CMC ）as composite reinforcing agents, glycerol as plasticizer to develop new composite packaging film by using single factor experimental method to determine the deposition process parameters and analyse film properties.Experimental results showed that crosslinked corn starch was 3.0% of the membrane solution,polyvinylalcohol（PVA）and carboxymethyl cellulose（CMC）solution was 3.0% ,glycerin was 3.0% ,straw stalk fiber was 1.0% .Tensile strength of the film was 19.67 MPa,elongation at break was up to 25.66%.
