Abstract

Effect of gamma radiation to biodegradable starch based had been developing and increase interest among the researchers. Starch blend with various synthetic and natural polymers will produce different result for each of it. This paper discussing for four polyesters that commonly used in the industry which are Polycaprolactone (PCL), Glycerol, Polyvinyl alcohol (PVA) and Polyethyleneglycol (PEG 300). By refer result from previous report, irradiated starch blend with PVA, PEG 300 and glycerol give positive result on mechanical and barrier properties. Tensile strength, water absorption and radiation effect for each polyester blend with irradiated starch were discussed. Gamma radiation improve the mechanical and barrier properties.
