The present study was to develop bioplastic from banana peels and characteristic its physical properties. The biofilm was prepared from banana peels by casting method using glycerol (10%) as a plasticizer and corn starch as co-biopolymer. The bioplastic with 8% corn starch (T₄) showed the highest tensile strength (0.388 MPa), while the bioplastic with 10% corn starch (T₅) had the highest water solubility and best water vapor transmission rate. The films' biodegradability, measured by carbon dioxide evolution, showed a gradual increase from day 7 to day 90. The highest tensile strength (0.388 MPa), elongation (9.77%), maximum load (2.48 N), and strong biodegradability, along with intermediate solubility (34.12%) and thickness (0.56 mm). increasing corn starch concentrations positively influenced the water vapor transmission rate. This research highlights the potential to transformation of banana peels into eco-friendly, value-added bioplastics.
