最近对塑料包装引起的环境问题的敏感性急剧增加，这促进了对替代可持续包装材料的兴趣。这一新趋势促进了壳聚糖基薄膜知识的工业化开发。壳聚糖因其独特的生物学和功能性而得到广泛的研究和应用。然而，包括低机械性能和对湿度的高敏感性在内的固有缺点代表了其工业应用（包括食品包装）的主要限制。在本研究中，对过去五年的科学文献进行了广泛的综述（来源：Web of Science），讨论了壳聚糖薄膜在食品包装行业中的潜在应用。本文总结了为克服壳聚糖薄膜的固有缺陷和提高其性能而采取的各种策略，特别是与天然和合成生物聚合物的共混。
The recent sharp increase of sensitivity towards environmental issues arising from plastic packaging has boosted interest towards alternative sustainable packaging materials. This new trend promotes the industrial exploitation of knowledge on chitosan-based films. Chitosan has been extensively investigated and used due to its unique biological and functional properties. However, inherent drawbacks including low mechanical properties and high sensitivity to humidity represent major limitations to its industrial applications, including food packaging. In the present study, the scientific literature of the last five years has been extensively reviewed (source: Web of Science) addressing chitosan-based films for their potential application in the food packaging industry. The contribution summarizes the various strategies adopted to overcome inherent drawbacks and improve the properties of chitosan-based films, with special regards for blending with natural and synthetic biopolymers.
