The aim of this research is to prepare poly(vinyl alcohol) (PVA) film and starch reinforce with cellulose fiber form Corn Husk by solution method for Biocomposite Film for Seedling. The polymer nanocomposites were prepared by mixing starch and PVA at dry weight ratios of 90/10, 80/20 and 70/30 and each of these with various amounts of cellulose fiber (1, 3 and 5 parts by weight per hundred of starch and PVA) The obtained homogeneous solution was casted into films using glass mold and dried at 60 oC in a hot air oven. The obtained polymer nanocomposites sheets have been characterized by Fourier-transform infrared spectroscopy, Tensile Testing, Differential Scanning Calorimetry, Scanning Electron Microscope and weight loss analysis. It was found that the addition of starch and cellulose fiber increase mechanical property of composite films (starch and cellulose fiber have to less than 30 and 3 %by weight, respectively). The mechanical results obtained from tensile analysis revealed that Young’s modulus of biocomposite films were enhanced with increasing cellulose fiber concentration, while a significant decrease was observed in elongation at break at the same concentration of cellulose. The melting point of composite film was increased with increasing of starch and cellulose fiber. After soil burial for 14 days, percent weight loss and biodegradability of the polymer nanocomposites enhanced as the amount of starch and cellulose were increased which can confirm by thermal analysis SEM images and weight loss analysis.
