Study on the characterization of thin film based on urea modified starch plasticized with ethylene glycol

This study aimed to formulate corn starch-based thermoplastic starch (TPS) films by varying concentrations of plasticizer which is ethylene glycol (EG) with and without polyvinyl alcohol (PVA). Furthermore, the resulted thin film was characterized by its mechanical and physical properties. Thermopla...
