摘要:本文综述了可降解阻隔涂层在纸基食品包装材料中的应用，系统地介绍了涂层的阻隔机理和涂料流变性，基底材料特性对涂层结构和材料阻隔性能的影响；并对纳米纤维素、聚乙烯醇（PVA）、聚羟基丁酸酯（PHB）、聚乳酸（PLA）、淀粉5种常见的可降解聚合物涂层材料的突出优势、不足之处和改性方法进行了对比和总结，对其应用价值进行了展望。

Abstract:The application of degradable barrier coatings in paper-based food packaging was reviewed. Firstly， the barrier mechanism and rheological features of the coatings were systematically introduced. Then， the effects of substrate material characteristics on coating structure and material barrier ability were analyzed. Finally， The advantages， disadvantages and modification methods of five common degradable polymer coating materials （nanocellulose， PVA， PHB， PLA， starch） were contrasted and summarized， and their application value was prospected.
