Effect of sweet water on some mechanical properties of biodegradable thermoplastic starch films
Patato starch was compounded with glycerol, poly(vinyl alc.) and keratin and then extruded to thin biodegradable films. The uni-axial stress-strain characteristics of the films were detd. by random markers method. The Young modulus and the breaking force of the films decreased with the increase of soaking time after first 15 s of soaking.
