Food sectors are facing issues as a result of food scarcity, which is exacerbated by rising populations and demand for food. Food is ordinarily wrapped and packaged using petroleum-based plastics such as polyethylene, polyvinyl chloride, and others. However, the excessive use of these polymers has environmental and health risks. As a result, much research is currently focused on the use of bio-based materials for food packaging. Biodegradable polymers that are compatible with food products are used to make edible packaging materials. These can be ingested with food and provide consumers with additional health benefits. Recent research has shifted its focus to multilayer coatings and films-based food packaging, which can provide a material with additional distinct features. The aim of this review article is to investigate the properties and applications of several bio-based polymers in food packaging. The several types of edible film and coating production technologies are also covered separately. Furthermore, the use of edible films and coatings in the food industry has been examined, and their advantages over traditional materials are also discussed.
由于食物短缺，食品行业正面临诸多问题，而人口增长和对食物的需求加剧了这一情况。食品通常使用聚乙烯、聚氯乙烯等石油基塑料进行包装。然而，过度使用这些聚合物存在环境和健康风险。因此，目前许多研究都集中在使用生物基材料进行食品包装。与食品兼容的可生物降解聚合物被用于制造可食用包装材料。这些材料可以与食物一起食用，并为消费者带来额外的健康益处。最近的研究已将重点转向基于多层涂层和薄膜的食品包装，这种包装可为材料提供额外的独特特性。这篇综述文章的目的是研究几种生物基聚合物在食品包装中的性能和应用。几种可食用薄膜和涂层的生产技术也分别进行了介绍。此外，还考察了可食用薄膜和涂层在食品工业中的应用，并讨论了它们相对于传统材料的优势。
