Chitosan-based composites play an important role in food packaging applications and can be used either as films or as edible coatings. Due to their high costs and lower performance (i.e., lower barrier against water vapor, thermal, and mechanical properties) when compared to the traditional petroleum-based plastics, the use of such biopolymers in large-scale is still limited. Several approaches of chitosan composites in the packaging industry are emerging to overcome some of the disadvantages of pristine polymers. Thus, this work intends to present the current trends and the future challenges towards production and application of chitosan composites in the food packaging industry.

基于壳聚糖的复合材料在食品包装应用中发挥着重要作用，可用作薄膜或可食用涂层。与传统的石油基塑料相比，由于其成本高且性能较低（即对水蒸气的阻隔性、热性能和机械性能较低），这种生物聚合物的大规模使用仍然受到限制。包装行业中出现了几种壳聚糖复合材料的方法，以克服原始聚合物的一些缺点。因此，这项工作旨在介绍壳聚糖复合材料在食品包装行业生产和应用方面的当前趋势和未来挑战。
