Research into alternative packaging materials is becoming more and more popular as a result of growing eco-friendly concerns regarding the usage of some petroleum-based polymeric packaging materials and coatings, as well as growing buyer demands for products with nutritious quality and extended shelf lives. Barrier coatings made of naturally renewable biopolymers can be applied to paper packing materials. These biopolymer coatings have the potential to replace the current synthetic paper and paperboard coatings, are strong oxygen and oil barriers, and may prevent the unintended moisture transfer in food goods. An appealing method of controlling the growth and spread of microorganisms in food packaging is the integration of antimicrobial compounds into coatings to create active/functional paper-based packaging materials. Here, in this review of the oxygen/moisture barrier, mechanical, and other characteristics of paper coated with bio-based materials. Examples are used to discuss the current and future uses of bio-based material coatings on paper packaging materials to improve barrier performance.

由于人们对使用某些石油基聚合物包装材料和涂料的环保问题日益关注，以及买家对营养品质和延长保质期的产品的需求不断增长，对替代包装材料的研究变得越来越受欢迎。由天然可再生生物聚合物制成的阻隔涂层可应用于纸包装材料。这些生物聚合物涂层有潜力取代当前的合成纸和纸板涂层，具有很强的氧气和油屏障作用，并且可以防止食品中意外的水分转移。控制食品包装中微生物生长和传播的一种有吸引力的方法是将抗菌化合物整合到涂料中以创建活性/功能性纸基包装材料。在此，我们回顾了涂有生物基材料的纸张的氧气/湿气阻隔性、机械特性和其他特性。通过实例讨论生物基材料涂层当前和未来在纸质包装材料上的应用，以提高阻隔性能。
