Abstract This study investigates the development of a novel biocomposite tailored for sustainable packaging applications, integrating cellulosic woven fiber mats into poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV), biocompatible polymer. Utilizing hot press compression molding, composite boards with thickness 3 mm were fabricated. The chemically modified propionic anhydride, enhancing their compatibility PHBV matrix. Varied concentrations reinforced propionylated (10%, 20%, 30%, 40%, and 50%) investigated. abaca composites exhibited superior functional properties, thermal stability, biodegradability, mechanical performance compared to pure Notably, properties showed significant improvement increased content, particularly achieving optimal strength at 30 wt% reinforcement. Chemical treatment enhanced interfacial bonding, evident in higher water contact angles confirmed by Field Emission Scanning Electron Microscopy (FE‐SEM) analysis. biodegradation rate biocomposites was faster control biopolymer. Despite potential agglomeration issues concentrations, PHBV/chemically hold promise as materials, contributing greener future applications. Highlights Successful preparation treated plant fibers. Propionic anhydride enhances fiber‐PHBV bonding resistance. Improved composites. Propionylated fibers enhance biodegradability Promising
