Abstract:This work is to produce multi‐functional active film from polyvinyl (alcohol)/chitosan (PCs) supplemented with Sonneratia ovata leaf extract (SOE) and Piper betel L. oil (PBLO). Our finding showed yellowish SOE‐added PCs film with the compact structure possessing lower swelling degree (SD) (22.48%) and higher mechanical strength (5.05 MPa) as compared to the neat PCs (35.43% and 3.18 MPa, respectively). While the co‐supplementation with PBLO at different ratios significantly increased SD between 50.97% and 104… Show more
