This literature review provides a focus on the potential of integrating the latest scientific and technological advances in the biological field to improve the status of the key steps of a food packaging life cycle: production, usage, post-usage, and long-term fate. A case study of such multi-biological food packaging is demonstrated based on the use of PHAs (polyhydroxyalkanoates) polymer, a microbiologically produced polymer from non-food renewable resources, activated by the use of bioactive components to enhance its usage benefits by reducing food loss and waste, displaying potential for reusability, compostability as post-usage, and finally, being ultimately biodegradable in most common natural conditions to considerably reduce the negative impact that persistent plastics have on the environment. We discuss how designing safe and efficient multi "bio" food packaging implies finding a compromise between sometimes contradictory functional properties. For example, active antimicrobials help preserve food but can hamper the ultimate biodegradation rate of the polymer. This review presents such antagonisms as well as techniques (e.g., coatings, nanoencapsulation) and tools (e.g., release kinetic) that can help design optimized, safe, and efficient active food packaging.
这篇文献综述聚焦于整合生物领域最新科技进展以改善食品包装生命周期关键步骤（生产、使用、使用后及长期归宿）状况的潜力。基于聚羟基脂肪酸酯（PHA）聚合物展示了这种多生物食品包装的案例研究，PHA是一种由非食品可再生资源经微生物生产的聚合物，通过使用生物活性成分激活，以通过减少食品损失和浪费来提高其使用效益，显示出可重复使用的潜力，使用后可堆肥，最终在大多数常见自然条件下可完全生物降解，从而大幅减少持久性塑料对环境的负面影响。我们讨论了设计安全高效的多“生物”食品包装如何意味着要在有时相互矛盾的功能特性之间找到平衡。例如，活性抗菌剂有助于保存食品，但可能会阻碍聚合物的最终生物降解速度。本综述介绍了此类拮抗作用以及有助于设计优化、安全和高效的活性食品包装的技术（如涂层、纳米封装）和工具（如释放动力学）。
