The dynamic stress-strain curves of starch-based biodegradable plastics were obtained at a room temperature over a wide range of strain rates from 10^<-5> s^<-1> to 10^4 s^<-1>, using a quasi-static compression testing machine and a split Hopkinson pressure bar (SHPB) method. Young's modulus and flow stress of biodegradable plastics are dependent upon the strain rate. Empirical equations for 7% flow stress were derived for the strain rates from 10^<-5> s^<-1> to 10^0 s^<-1> and from 10^3 s^<-1> to 10^4 s^<-1>. It is also found that the attenuation of stress waves is quite large.
