摘要

目的梳理总结液态食品塑胶包装高性能材料的研究现状及技术难点,展望其发展趋势及绿色转型方向,为我国液态食品塑胶包装的高性能材料研发、安全评价及绿色转型提供理论参考。方法系统分析食品级再生塑料、生物基与可堆肥材料、功能集成材料的研究进展,重点探讨液态体系对阻氧、耐酸、耐应力开裂等特殊性能要求及其材料失效机制。结果在食品级再生塑料方面,欧美法规体系较为成熟,我国尚处在政策探索期,非有意添加物的识别及迁移仍是重大瓶颈,亟待建立本土化风险评估体系;生物基材料通过共混、纳米增强、绿色交联等改性方式可提高性能,但其在酸性、高水分液态食品中的应用边界尚不明确,相关安全性数据仍待完善;抗菌、活性、智能包装等功能集成材料研究发展迅速,为包装性能提升提供新的技术路径,但可回收性问题仍需重视。结论液态食品塑胶包装高性能材料的未来发展应构建以“同级循环”为资源基础、以“场景适配”为技术导向、以“易回收设计”为关键保障的系统发展体系,形成“同级循环（再生塑料）-场景适配（生物基材料）-易回收设计（功能集成材料）”的三位一体协同发展体系。

Abstract

The work aims to provide a systematic review of the current research landscape and technical bottlenecks in high-performance plastic packaging materials for liquid foods, look forward to its development trend and green transformation direction, and provide theoretical references for the research and development of high-performance materials, safety assessment and green transformation of liquid food plastic packaging in China. The systematic analysis covered three major fronts, namely food-grade recycled plastics, bio-based and compostable materials, and functionally integrated materials, with particular attention paid to the stringent demands imposed by liquid systems, such as oxygen barrier performance, acid resistance, and stress-crack resistance, alongside the associated failure mechanisms. In the realm of food-grade recycled plastics, regulatory frameworks are well-established in Europe and the United States, whereas China is still navigating its policy formulation phase; the identification and migration behavior of non-intentionally added substances (NIAS) remain critical hurdles, and there is an urgent need to establish a localized risk assessment system. Bio-based and compostable materials have shown performance improvements through blending, nano-reinforcement, and green cross-linking, yet their practical application boundaries in acidic or high-moisture liquid foods are still ill-defined, and corresponding safety data are insufficient. Research on functionally integrated materials, including antibacterial, active, and intelligent packaging, is highly active and offers advanced barrier solutions, but recyclability issues continue to pose significant challenges. Looking ahead, the sustainable advancement of liquid-food plastic packaging should be built upon a systematic engineering framework anchored in "same-level recycling" as the resource foundation, "scenario-adaptive design" as the technical orientation, and "easy-recyclability" as the key enabler for closed-loop systems, thereby fostering a tripartite synergistic system that harmonizes "same-level recycling (recycled plastics), scenario adaptation (bio-based materials) and easy-recyclability design (functionally integrated materials)".
