塑料包装在社会各个方面都得到了越来越多的关注。在过去的几十年里，塑料因其优异的性能、性能和经济性而成为首选材料，但塑料的寿命结束并没有得到很好的管理。这导致了我们环境中的塑料垃圾，特别是海洋，河流和河口，推动立法，工业和自愿倡议，使必要的支点循环。虽然塑料回收行业在其相对较短的生命周期内取得了许多进展，但仍有许多技术和社会障碍需要克服。这项工作的目标不是提供一个完整的审查回收，因为它涉及到循环，而是强调需要由整个塑料社区合作解决，以实现循环的技术差距。这条道路上的每一个沿着阶段，从包装和建筑材料的设计到分类、回收和再加工，都是创新的成熟阶段。介绍了最相关的问题，为聚合物科学的所有领域的研究提供了一个起点，以帮助减少塑料包装废物对环境的影响。
Plastic packaging has gained an increasing amount of attention in all aspects of society. Over the past several decades, plastics became the material of choice due to their excellent properties, performance, and economics, but the end of life of plastics is not well managed. This has led to plastic waste in our environment, especially the oceans, rivers, and estuaries, driving legislative, industrial, and voluntary initiatives to make the necessary pivot to circularity. While the plastics recycling industry has made many advances in its relatively short life, there are still many technical and societal hurdles to be overcome. The goal of this work is not to provide a complete review of recycling as it pertains to circularity, but rather to highlight the technical gaps that need to be collaboratively addressed by the entire plastics community to achieve circularity. Each stage along the path, from design of packaging and materials of construction to sortation, recycling, and reprocessing are ripe for innovation. The most relevant issues are introduced to provide a starting point for research across all fields of polymer science to aid in reducing the environmental impact of plastic packaging waste.
