Non-degradable plastic places a serious burden on the environment, so consumers and researchers are working to develop biodegradable, safe, and sustainable food packaging materials. The starch-based film has become emerging material for food packaging. Not only does it shows excellent physicochemical properties, but also provides the desired degradation characteristics after use or the digestive properties after consumption, thus needing to comprehensively evaluate the quality of starch-based food packaging materials. This review summarizes the degradation behavior of the starch-based film in different degradation environments, and compares the suitability of degradation environments. Besides, the physicochemical properties of the composite or blend film during the degradation process were further discussed. The factors affecting the digestibility of starch-based edible film were reviewed and analyzed. Finally, the application and the future trend of the biodegradable starch-based film in the food packaging field were proposed. Future studies should combine and evaluate the physical properties and biodegradability of the composite/blend film, to develop food packaging materials with good characteristics and biodegradability.
不可降解塑料对环境造成了严重负担，因此消费者和研究人员正在努力开发可生物降解、安全和可持续的食品包装材料。淀粉基薄膜已成为食品包装的新兴材料。它不仅表现出优异的物理化学性能，而且在使用后或消费后提供所需的降解特性，因此需要综合评估淀粉基食品包装材料的质量。本综述总结了淀粉基薄膜在不同降解环境中的降解行为，并比较了降解环境的适宜性。此外，还进一步讨论了复合或共混膜在降解过程中的物理化学性质。综述了影响淀粉基可食用膜消化性的因素，并进行了分析。最后，提出了可生物降解淀粉基薄膜在食品包装领域的应用和未来发展趋势。未来的研究应结合和评估复合/共混膜的物理性能和生物降解性，开发具有良好特性和生物降解性的食品包装材料。
