目的 介绍羧甲基纤维素与淀粉、海藻酸钠、明胶、纳米纤维素、壳聚糖和其他材料制备复合膜在国内外的研究进展，以及该类具有抑菌性能的食品包装复合膜的最新研究进展，为羧甲基纤维素复合膜的研究提供一定的思路和依据。方法 总结该方向研究中不同材料的最佳添加量对羧甲基纤维素复合膜性能的提升情况，及一些复合膜添加不同的有机抑菌剂或无机抑菌剂后抑菌性能的提升情况和对一些食品的保鲜效果。结论 羧甲基纤维素复合膜具有较大的应用潜力，添加一些材料后具有抑菌活性，该类复合膜在食品保鲜方面具有一定的应用价值。

The work aims to introduce the research progress of preparing composite film by CMC and starch, sodium alginate, gelatin, nanocellulose, chitosan and other materials at home and abroad and the latest research progress of such food packaging composite film with antibacterial properties, so as to provide certain ideas and basis for the research of carboxymethyl cellulose composite film. The improvement of carboxymethyl cellulose composite film performance by the optimum addition amount of different materials was summarized in this research direction and the enhancement of antibacterial properties of some composite films after addition of different organic or inorganic antibacterial agents and the preservation effect on some food were also concluded. The carboxymethyl cellulose composite film has a great application potential. Some of the added materials have antibacterial activity and this type of composite film has certain application value in food preservation.
