Food packaging is an important concept for consumer satisfaction and the increased shelf life of food products. The introduction of novel food packaging materials has become an emerging trend in recent years, which could be mainly due to environmental pollution caused by plastic packaging and to reduce food waste. Recently, numerous studies have been carried out on nanoclays or nanolayered silicate to be used in packaging material development as reinforcing filler composites. Different types of nanoclays have been used as food packaging materials, while montmorillonite (MMT), halloysite, bentonite (BT), Cloisite, and organically modified nanoclays have become of great interest. The incorporation of nanoclays into the packaging matrix improves the mechanical and barrier properties and at the same time prolongs the biodegradation of the packaging material. The purpose of this article is to examine the development of nanoclay-based food packaging materials. The review article highlights the current state of research on bio-based polymers with nanoclay for food packaging. In addition, the report analyses the mechanical, barrier, and antibacterial characteristics of nanoclay-based food packaging materials. Finally, it discusses the migration of nanoclays, toxicity levels, and the legislation associated with the application of nanoclays.
食品包装对于消费者满意度和延长食品保质期而言是一个重要概念。近年来，新型食品包装材料的引入已成为一种新兴趋势，这可能主要是由于塑料包装造成的环境污染以及为了减少食品浪费。最近，人们对用于包装材料开发的纳米粘土或纳米层状硅酸盐进行了大量研究，将其作为增强填料复合材料。不同类型的纳米粘土已被用作食品包装材料，其中蒙脱石（MMT）、埃洛石、膨润土（BT）、有机改性蒙脱石（Cloisite）以及有机改性纳米粘土都备受关注。将纳米粘土加入包装基体中可改善机械性能和阻隔性能，同时延长包装材料的生物降解时间。本文的目的是研究基于纳米粘土的食品包装材料的发展情况。这篇综述文章重点介绍了用于食品包装的含纳米粘土生物基聚合物的研究现状。此外，该报告分析了基于纳米粘土的食品包装材料的机械性能、阻隔性能和抗菌特性。最后，讨论了纳米粘土的迁移、毒性水平以及与纳米粘土应用相关的法规。
