Abstract Fabricating a biodegradable packaging material is the requirement of this era to safeguard our planet from climatic change and waste management issues. Almost 55% of the waste was generated from packaging material used for various purposes. We have developed a biodegradable PVA/PPP composite film for dry packaging. The Polyvinyl alcohol (PVA) water soluble, biodegradable polymer was taken as the matrix, and pomegranate peel powder (PPP) the agro waste material was chosen as the filler material. The developed PVA/PPP composite films were characterized with optical microscopy, FTIR, XRD, TGA and moisture analysis. The addition of the filler PPP into the matrix PVA, increased the moisture absorption tendency, decreased the rate of water solubility of the PVA matrix, decreased the crystallinity of the matrix PVA and increased the thermal stability upto 423°C. The pH of the PPP filler material is 4.5, which assist in the preventing the microbial attack. All these characterizations revealed that the developed PVA/PPP composite films have better thermal stability over the matrix PVA. These PVA/PPP composite films can be used as packaging material for dry food substances, electronics, and other moisture free materials. The fabricated PVA/PPP composite films were completely biodegradable and developed via green synthesis without using hazardous materials. Another advantage over the fabrication was the utilization of the filler material PPP which will reduce the solid waste in the environment.
