This study aims to produce starch-based bioplastic that is environmentally safe and reduces pollution. This research aims to investigate the effect of betel leaf extract as an antimicrobial agent on the characteristic of bioplastic based on jack fruit seed starch. Bioplastics are the only solution to replace plastics. As a result, these nonbiodegradable plastics remain in the environment for a long time and cause an increase in solid waste production. Starch is one of the major sources in the development of bioplastics. The bioplastic was produced from the starch of jackfruit seed along with glycerol as a plasticizer and analyzed for its physical and mechanical properties. The bioplastic produced was analysed for its antimicrobial activity. The produced bioplastic showed better physio mechanical properties and can be used widely in industries. Keywords: Bioplastics, Glycerol, Jackfruit, Cornleaf, Betel leaf.
