Abstract
Abstract Plastic products are difficult to be degraded and cause environmental problem. To overcome this, plastic material is made from biodegradable natural resource which is called bioplastics. The aim of this research is to know the potency of mango seed starch, nanoparticle zinc oxide as filler and ethylene glycol as plasticizer. The mango seed starch size of 5 grams, with variation of zinc oxide filler mass of 0; 3; 6 and 9% (wt) and ethylene glycol 0; 20; 25; 30 and 35% (wt). The bioplastics films was analyzed the mechanical properties include tensile strength, elongation at break, SEM and FTIR. The optimum result obtained at nanoparticle ZnO concentration 6% and ethylene glycol 25% with tensile strength 3.78 MPa and elongation at break 2.23%. The SEM and FTIR result prove that addition of filler and plasticizer gives better surface morphology and dispersion in the bioplastics.
