Starch biopolymer films incorporated with chitosan nanoparticles (CNP) or starch/CNP films are promising alternatives to non-degradable food packaging materials. The films can be utilized for active food packaging applications because CNP exhibits antimicrobial and antioxidant properties, which can improve food shelf-life. Nonetheless, knowledge of the effects of CNP inclusion on the properties of starch films is not fully elucidated. This paper reviews the influences of various concentrations of CNP, sizes of CNP, and other additives on the mechanical, thermal, barrier, antimicrobial, antioxidant, biodegradability, and cytotoxicity properties of starch/CNP films as well as the mechanisms involved in relation to food packaging applications. The usage of starch/CNP films for active food packaging can help to reduce environmental issues and contribute to food safety and security.
淀粉基生物聚合物薄膜中加入壳聚糖纳米粒子（CNP）或淀粉/CNP 薄膜是有前途的替代不可降解的食品包装材料。这些薄膜可用于活性食品包装应用，因为 CNP 具有抗菌和抗氧化性能，可延长食品保质期。然而，CNP 对淀粉薄膜性能影响的知识还没有完全阐明。本文综述了不同浓度的 CNP、CNP 的粒径以及其他添加剂对淀粉/CNP 薄膜的力学性能、热性能、阻隔性能、抗菌性能、抗氧化性能、生物降解性能和细胞毒性的影响，以及与食品包装应用相关的作用机制。使用淀粉/CNP 薄膜进行活性食品包装有助于减少环境问题，有助于食品安全和保障。
