摘要 为制备高强度羧甲基纤维素（Carboxymethyl cellulose,CMC）包装膜,通过对各成分添加量的分析,寻找最佳工艺条件.就CMC、聚乙二醇（PEG-400）和无水乙醇添加量对CMC包装 膜性能的影响进行了研究,并对各因素进行了响应面分析,对CMC膜的最佳工艺配方进行了研究.结果表明：在一定条件下,CMC膜的物理机械性能随CMC、 PEG-400和无水乙醇添加量的升高先增大后降低,响应面分析得到制备200 mm×200 mm CMC膜的最佳工艺参数：40 m L水中CMC 2.0 g,ω（PEG-400）=30%,无水乙醇添加量10 m L,此时膜的拉伸强度为19.53 MPa,断裂伸长率为39.82%.
Abstract：In order to prepare high strength carboxymethyl cellulose （ CMC ） packaging film, the additive amount of each component was analysed to find the best process conditions. Effect of additive amount of CMC, PEG-400 and ethanol on the packaging film properties was studied, and the factors of response surface test was analysed. The optimum formula of CMC film was studied. The results showed that under certain conditions, with the additive amount of CMC, PEG-400 and ethanol increased, the physical and mechanical properties of CMC films increased first and then decreased, the optimum process parameters of 200 mm ×200 mm CMC film by response surface analysis were obtained： 2.0 g CMC, ω（PEG-400） = 30%, and 10 mL ethanol in 40 mL water, the tensile strength of the film was 19.53 MPa, the elongation was 39.82%.
