Due to the increased pollution generated from traditional petroleum-based plastics and consistent fluctuations in fuel prices, the scientists are focusing on developing the biodegradable polymers which decompose into water and carbon dioxide thereby reducing the litter. Poly(ε-caprolactone) (PCL) is the emerging biodegradable polymers, ideal to replace the conventional polymers due to its perfect compatibility with other polymers and miscible nature. The present chapter discusses about the chemical synthesis and characteristics of PCL in addition to focusing on the biodegradation mechanism. The potential of PCL for developing biodegradable films and bags in food processing is also highlighted in association with natural fibre, nanotechnology and active packing. This chapter provides an updated information about recent scientific reports on PCL to increase its exploration as a promising biodegradable packaging material.

聚（ε-己内酯）：一种用于可生物降解食品包装应用的潜在聚合物

由于传统石油基塑料产生的污染增加以及燃料价格的持续波动，科学家们正专注于开发可分解成水和二氧化碳从而减少垃圾的可生物降解聚合物。聚（ε-己内酯）（PCL）是新兴的可生物降解聚合物，由于其与其他聚合物的完美相容性和混溶性质，是替代传统聚合物的理想选择。本章除了重点讨论生物降解机制外，还讨论了 PCL 的化学合成和特性。PCL 在食品加工中开发可生物降解薄膜和袋子的潜力也与天然纤维、纳米技术和活性包装相结合。
