摘　　要：随着国内限塑令的发布,可降解塑料成为当前研究热点。应用广泛的可降解塑料如PLA、PBAT等塑料母料制成包装袋成本较高,不能良好适应现有市场规则。对PBS塑料进行发泡处理,利用TPU和淀粉使其粘附于纸质材料上,制备出一种新型可降解包装袋。此新型可降解包装袋单面回弹力最高可达到153 N、45天相对降解率达52.6%,环保无毒,是一种推广可降解塑料的良好选择。With the release of the domestic plastic restriction order,degradable plastics have become a current research hotspot.The cost of packaging bags made from widely used degradable plastics such as PLA,PBAT and other plastic masterbatches is high,and it cannot well adapt to the existing market rules.The PBS plastic was foamed and adhered to the paper material by using TPU and starch to prepare a new type of degradable packaging bag.This new type of degradable packaging bag has a resilience of 153 N on one side and a degradation rate of 52.6%in 45 days.It is low in cost,environmentally friendly and non-toxic.It is a good choice for promoting degradable plastics.
