Recent years have witnessed great developments in biobased polymer packaging films for the serious environmental problems caused by the petroleum-based nonbiodegradable packaging materials. Chitosan is one of the most abundant biopolymers after cellulose. Chitosan-based materials have been widely applied in various fields for their biological and physical properties of biocompatibility, biodegradability, antimicrobial ability, and easy film forming ability. Different chitosan-based films have been fabricated and applied in the field of food packaging. Most of the review papers related to chitosan-based films are focusing on antibacterial food packaging films. Along with the advances in the nanotechnology and polymer science, numerous strategies, for instance direct casting, coating, dipping, layer-by-layer assembly, and extrusion, have been employed to prepare chitosan-based films with multiple functionalities. The emerging food packaging applications of chitosan-based films as antibacterial films, barrier films, and sensing films have achieved great developments. This article comprehensively reviews recent advances in the preparation and application of engineered chitosan-based films in food packaging fields.
近年来，由于石油基不可生物降解包装材料引发了严重的环境问题，生物基聚合物包装薄膜取得了巨大进展。壳聚糖是仅次于纤维素的最丰富的生物聚合物之一。基于壳聚糖的材料因其生物相容性、生物降解性、抗菌能力和易于成膜的特性，已在各个领域得到广泛应用。不同的基于壳聚糖的薄膜已被制备并应用于食品包装领域。大多数与基于壳聚糖的薄膜相关的综述文章都集中在抗菌食品包装薄膜上。随着纳米技术和聚合物科学的进步，许多策略，如直接浇铸、涂层、浸渍、层层组装和挤出，已被用于制备具有多种功能的基于壳聚糖的薄膜。基于壳聚糖的薄膜作为抗菌薄膜、阻隔薄膜和传感薄膜在新兴食品包装应用中取得了巨大进展。本文全面综述了工程化基于壳聚糖的薄膜在食品包装领域的制备和应用的最新进展。
