| 本文系统综述了生物质基可降解阻隔包装材料的研究现状与发展方向，分析了包括聚乳酸基、淀粉基、纤维素基及纸基等材料体系的优势及面临的关键挑战（如阻隔性能和机械强度不足、成本高等）；深入探讨了用于提升材料阻隔性能的改性技术的优缺点及适用性，如共混改性（如淀粉/聚乳酸）、纳米复合增强（利用“迷宫效应”）、本体疏水改性（化学修饰）和涂布改性（如纸基材料的多功能涂层）等；展望了开发高相容性生物质基阻隔剂、优化结构、改善纳米分散等技术的发展前景，旨在为生物质基可降解阻隔包装材料的科技创新与产业升级提供参考。 |
| Abstract: |
| This paper systematically reviewed the research status and development directions of biomass-based biodegradable barrier packaging materials. It analyzed the advantages and key challenges faced by material systems including polylactic acid （PLA）-based， starch-based， cellulose-based， and paper-based materials， such as poor barrier performance and mechanical strength， as well as high costs. The study further explored modification techniques used to enhance the barrier properties of these materials， such as blending modification （e.g.， starch/PLA）， nanocomposite reinforcement （utilizing the “labyrinth effect”）， intrinsic hydrophobic modification （chemical modification）， and coating modification （e.g.， multifunctional coatings for paper-based materials）， along with their respective advantages， disadvantages， and applicability. Finally， the outlook highlighted the development prospects of technologies of highly compatible bio-based barrier agents， structural optimization， and improvement of nanomaterial dispersion， aiming to provide references for technological innovation and industrial upgrading of bio-based biodegradable barrier packaging materials. |
