Preparation film gelatin PVA/gelatin and characterization mechanical properties

It has been done the preparation of film PVA and gelatin film using drop casting method. Drop casting is a method of pouring the solution into a Petri dish which dried at temperature 80 °C. Solution PVA 10% was prepared by dissolving 0.1 gram of PVA powder in 100 ml of distilled water while the gelatin film was made from 5% gelatin (0.05 gram solution of gelatin powder in 100 ml of distilled water). The PVA fillm and gelatin film produced were tested mechanically by tensile test.
