The accumulation of high amounts of petro-based plastics is a growing environmental devastation issue, leading to the urgent need to innovate eco-safe packaging materials at an equivalent cost to save the environment. Among different substitutes, starch-based types and their blends with biopolymers are considered an innovative and smart material alternative for petrol-based polymers because of their abundance, low cost, biodegradability, high biocompatibility, and better-quality film-forming and improved mechanical characteristics. Furthermore, starch is a valuable, sustainable food packaging material. The rising and growing importance of designing starch-based films from various sources for sustainable food packaging purposes is ongoing research. Research on "starch food packaging" is still at the beginning, based on the few studies published in the last decade in Web of Science. Additionally, the functionality of starch-based biodegradable substances is technically a challenge. It can be improved by starch modification, blending starch with other biopolymers or additives, and using novel preparation techniques. Starch-based films have been applied to packaging various foods, such as fruits and vegetables, bakery goods, and meat, indicating good prospects for commercial utilization. The current review will give a critical snapshot of starch-based films' properties and potential applicability in the sustainable smart (active and intelligent) new packaging concepts and discuss new challenges and opportunities for starch bio composites.
大量石油基塑料的积累是一个日益严重的环境破坏问题，这导致迫切需要以同等成本创新生态安全的包装材料以拯救环境。在不同的替代品中，淀粉基类型及其与生物聚合物的共混物被认为是石油基聚合物的一种创新且智能的材料替代品，因为它们储量丰富、成本低、可生物降解、生物相容性高，并且具有更好的成膜质量和改进的机械特性。此外，淀粉是一种有价值的可持续食品包装材料。出于可持续食品包装目的，从各种来源设计淀粉基薄膜的重要性日益凸显，相关研究正在进行中。基于过去十年在《科学引文索引》上发表的少数研究，关于“淀粉食品包装”的研究仍处于起步阶段。此外，淀粉基可生物降解物质的功能在技术上是一项挑战。可以通过淀粉改性、将淀粉与其他生物聚合物或添加剂共混以及使用新颖的制备技术来改善。淀粉基薄膜已应用于包装各种食品，如水果和蔬菜、烘焙食品和肉类，显示出良好的商业利用前景。本综述将对淀粉基薄膜的特性及其在可持续智能（活性和智能）新包装概念中的潜在适用性进行批判性概述，并讨论淀粉生物复合材料面临的新挑战和机遇。
