目的 为了应对日益恶化的全球气候变化，并实现碳中和的目标，研究低碳化技术在包装行业的应用成为当下至关重要的任务。为了推动包装行业在碳中和背景下的低碳化转型，有必要对现有的低碳化技术进行分类和梳理。方法 从碳减排和碳移除两方面对包装行业已有的低碳化技术进行了研究。综述当前可降解生物塑料和聚合物单体化学循环技术在包装中的应用，介绍了几种清洁能源以及碳捕捉、碳利用和碳储存技术的发展现状。结论 对包装行业而言，实现碳中和的目标还面临着很多挑战。包装行业在推进碳中和目标时要选取与发展适合的低碳能源和碳中和技术。

To address the increasingly worsening global climate change and achieve carbon neutrality and achieve carbon neutrality, it is an essential task to study the application of low-carbon technologies in the packaging industry. The work aims to categorize and streamline the existing low-carbon technologies to facilitate the low-carbon transformation of the packaging industry in the context of carbon neutrality. The low-carbon technologies in the packaging industry were summarized from both carbon reduction and carbon removal. The application of degradable bioplastics and polymer monomer chemical recycling technologies in packaging were reviewed. The current development of several clean energy and carbon capture, carbon utilization and carbon storage technologies were introduced. For the packaging industry, there are still many challenges to achieve carbon neutrality. The packaging industry should select and develop the right low-carbon energy sources and carbon-neutral technologies in realizing carbon neutrality.
