Food packaging was not as important in the past as it is now, because the world has more people but fewer food resources. Food packaging will become more prevalent and go from being a nice-to-have to an essential feature of modern life. Food packaging has grown to be an important industry sector in today's world of more people and more food. Food packaging innovation faces significant challenges in extending perishable food products' shelf life and contributing to meeting daily nutrient requirements as people nowadays are searching for foods that offer additional health advantages. Modern food preservation techniques have two objectives: process viability and safe, environmentally friendly end products. Long-term storage techniques can include the use of edible coatings and films. This article gives a succinct overview of the supplies and procedures used to coat food products with conventional packaging films and coatings. The key findings summarizing the biodegradable packaging materials are emphasized for their ability to prolong the freshness and flavor of a wide range of food items; films and edible coatings are highlighted as viable alternatives to traditional packaging methods. We discuss the safety concerns and opportunities presented by applying edible films and coatings, allowing it to be used as quality indicators for time-sensitive foods.
食品包装在过去不像现在这样重要，因为世界上的人口增加了，但粮食资源却减少了。食品包装将变得更加普遍，从可有可无变成现代生活的基本特征。在当今这个人口更多、食物更多的世界里，食品包装已经发展成为一个重要的产业部门。食品包装创新面临着延长易腐食品保质期和满足日常营养需求的巨大挑战，因为现在人们正在寻找提供额外健康益处的食品。现代食品保鲜技术有两个目标：工艺可行性和安全、环保的最终产品。长期储存技术可以包括使用可食用的涂层和薄膜。本文简要概述了用于给食品产品涂上传统包装薄膜和涂层的材料和工艺。强调了可生物降解包装材料的关键发现，因为它们能够延长各种食品的新鲜度和风味；薄膜和可食用涂层被视为传统包装方法的可行替代品。我们讨论了应用可食用薄膜和涂层带来的安全问题和机遇，使它们能够用作对时间敏感的食品的质量指标。
