摘要： A biodegradable film comprises from 1 wt % to 10 wt % of a first polyhydroxyalkanoate resin component, from 50 wt % to 90 wt % of a second polyhydroxyalkanoate resin component, and from 5 wt % to 48 wt % of a polybutylene adipate terephthalate resin. Specifically, the first poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) resin contains a first mol % of 3-hydroxyhexanoate structural units, and the second poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) resin contains a second mol % of 3-hydroxyhexanoate structural units, while the second mol % is higher than the first mol %, e.g., by 2-40 mol %, or 3-30 mol %, or 4-20 mol %.
