Over the past few decades, plastic products have brought great convenience to people’s lives, but due to improper disposal, a large amount of plastic waste has caused many environmental problems. Currently, the global annual production of disposable plastic products reaches 120 million tons, of which only 10% is recycled, another 12% is incinerated, and more than 70% is discarded into the soil, air, and oceans (Yujun and Dawei 2018). Therefore, it is important to increase consumer awareness of biodegradable polymer materials and introduce them to the market. Presently, biodegradable plastics in China are still in the early stages of industrialization, and the issuance of plastic restriction and ban orders has provided a huge market opportunity for degradable plastics.
