Abstract: Abstract The present invention relates to the development of a biodegradable jackfruit {Artocarpus heterophyllus) latex-reinforced polyvinyl alcohol (PVA)-silver nanocomposite film for active antimicrobial food packaging applications. The invention combines the excellent film-forming ability of polyvinyl alcohol, the natural reinforcing and adhesive properties of jackfruit latex, and the broad-spectrum antimicrobial activity of green synthesized silver nanoparticles to produce an environmentally friendly packaging material. Fresh jackfruit latex is purified and incorporated into a homogeneous PVA matrix containing biosynthesized silver nanoparticles prepared through an eco-friendly green synthesis process. The resulting nanocomposite solution is cast into flexible transparent films and characterized using UVVisible spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDX), and Thermogravimetric Analysis (TGA). Mechanical strength, thermal stability, moisture barrier properties, oxygen permeability, biodegradability, and antimicrobial performance are evaluated using standard analytical procedures. J The fabricated nanocomposite film, exhibits enhanced tensile strength, flexibility, thermal stability, moisture resistance, and broad-spectrum antimicrobial activity against common foodborne pathogens including Escherichia coli. Staphylococcus aureus. Salmonella enterica, and Listeria monocytogenes. Food packaging studies demonstrate prolonged shelflife, reduced microbial contamination, and improved preservation of food quality during storage. The invention provides a simple, economical, biodegradable, and sustainable alternative to conventional plastic food packaging materials. The developed antimicrobial nanocomposite film has significant potential for commercial food packaging, pharmaceutical packaging, biomedical materials, and environmentally friendly industrial applications. Key words: Jackfruit latex, Artocarpus heterophyllus, Polyvinyl alcohol (PVA), Silver nanoparticles, Green synthesis, Nanocomposite film, Active food packaging, Antimicrobial packaging, Biodegradable polymer, Food preservation, Sustainable packaging, Shelflife extension.
