Abstract

The search for sustainable green alternatives in food packaging continues, as petroleum-based plastics remain a major environmental and health concern. Among naturally abundant polymers, starch is an attractive candidate due to its substantial availability, low cost, and structural flexibility for targeted modifications. This review critically examines potential starch sources for biodegradable film fabrication, highlighting physical and thermal modifications that have achieved notable performance gains—for example, acetylation improving tensile strength by up to 35 % and nanocellulose reinforcement reducing oxygen permeability by over 50 %. Film-making methods such as solution casting, extrusion, and blow moulding are evaluated for their influence on mechanical and barrier properties. The integration of nanocarriers and bioactive compounds is discussed in relation to mechanical enhancement, barrier improvement, and shelf-life extension. Additionally, processing parameters including moisture content, drying methods, and temperature are assessed for their impact on final film performance. Inorganic nanofillers such as zinc oxide, carbon nanotubes, graphene oxide, and titanium dioxide are compared with sustainable bio-based fillers, emphasizing their property enhancements and safety considerations. Unlike earlier reviews, this work synthesizes recent advances (2020–2024) with a dual focus on performance metrics and regulatory implications, providing a concise framework for guiding future development of high-performance, sustainable starch-based food packaging materials.
用于可持续食品包装薄膜的淀粉的物理、化学和纳米改性:最近的趋势、挑战和前景
寻找可持续的绿色食品包装替代品的工作仍在继续,因为石油基塑料仍然是一个主要的环境和健康问题。在天然丰富的聚合物中,淀粉是一个有吸引力的候选者,因为它具有大量的可用性,低成本和结构灵活性的靶向修饰。这篇综述严格审查了生物可降解薄膜制造的潜在淀粉来源,强调了物理和热改性已取得显着性能增益的淀粉来源,例如,乙酰化可提高高达35%的拉伸强度,纳米纤维素增强可降低50%以上的透氧性。薄膜制作方法,如溶液铸造、挤压和吹塑,评估了它们对机械和阻隔性能的影响。纳米载体和生物活性化合物的整合讨论了机械增强、屏障改善和保质期延长的关系。此外,还评估了包括水分含量、干燥方法和温度在内的加工参数对最终薄膜性能的影响。将氧化锌、碳纳米管、氧化石墨烯和二氧化钛等无机纳米填料与可持续生物基填料进行比较,强调其性能增强和安全性考虑。与之前的综述不同,本研究综合了近期进展(2020-2024),双重关注性能指标和监管影响,为指导高性能、可持续淀粉基食品包装材料的未来发展提供了一个简洁的框架。
