Abstract

Biodegradable polymer composites (BPCs) emerge as a promising solution to the escalating plastics pollution crisis. This review comprehensively analyzes their multifaceted properties, including mechanical strength, gas barrier function, and biodegradation rates, emphasizing their potential for tailored applications in food, beverage, and pharmaceutical packaging. By delving into the optimization of BPC characteristics, we illustrate how these materials can enhance product integrity and extend shelf life, crucial for maintaining the quality and safety of packaged goods. Scalable and cost-effective manufacturing techniques are critically examined, aiming to bridge the gap toward commercial viability and widespread adoption of BPCs. Beyond biodegradability, the adherence to stringent environmental standards is emphasized, promoting a circular economy within packaging through material recovery and reintegration processes. Life cycle assessment (LCA) studies are incorporated to provide a holistic environmental perspective, evaluating the overall impact of BPCs from production to disposal. Industry perspectives are integrated to assess the economic feasibility of BPC adoption across diverse sectors, analyzing potential cost benefits and challenges in integrating BPCs into existing production lines. Finally, the evolving regulatory landscape surrounding BPCs is addressed, highlighting both challenges and opportunities for their widespread adoption. This comprehensive analysis serves as a valuable resource for industry and academia, advocating for BPCs as a crucial step toward a sustainable future for packaging, combining environmental responsibility with practical application.

探索用于可持续包装的可生物降解聚合物复合材料:性能、制造技术和环境影响综述
可生物降解聚合物复合材料(BPCs)是解决不断升级的塑料污染危机的一个前景广阔的方案。本综述全面分析了它们的多方面特性,包括机械强度、气体阻隔功能和生物降解率,强调了它们在食品、饮料和药品包装领域的定制应用潜力。通过深入探讨 BPC 特性的优化,我们说明了这些材料如何能够提高产品的完整性并延长保质期,这对保持包装产品的质量和安全性至关重要。我们对可扩展和具有成本效益的制造技术进行了严格审查,旨在缩小 BPC 在商业可行性和广泛采用方面的差距。除了生物降解性之外,还强调要遵守严格的环境标准,通过材料回收和再整合过程促进包装内的循环经济。研究纳入了生命周期评估(LCA)研究,以提供一个整体的环境视角,评估 BPC 从生产到处置的整体影响。此外,还纳入了行业视角,以评估不同行业采用 BPC 的经济可行性,分析将 BPC 集成到现有生产线中的潜在成本效益和挑战。最后,还讨论了围绕 BPC 不断变化的监管环境,强调了广泛采用 BPC 所面临的挑战和机遇。这份全面的分析报告为工业界和学术界提供了宝贵的资源,倡导将 BPC 作为实现包装可持续未来的关键一步,将环境责任与实际应用相结合。
