Utilization of bio-waste material pomegranate peel powder along with silver nitrate and polyvinyl alcohol to form a hybrid biofilm

This work aims to convert the bio-waste material into a fruitful product. This prepared product can be a solution for environmentally hazardous materials like polymer bags and plastic food wrappers. The prepared material is composed of bio-waste pomegranate peel powder and environmentally friendly polyvinyl alcohol. To extend its functionality in food wrappers, the silver nitrate solution is incorporated. The prepared samples were undergone various performance studies. The prepared films show high thermal with standing capacity and tensile properties and especially show better results in biodegradability as well as antibacterial activity. Among the fabricated films, the 5 mM AgNO3-fabricated film shows that the thermal stability up to 331 °C also possesses higher tensile strength of 25.7 MPa. These results make the possibilities of the fabricated PP/PVA/5 mM AgNPs film as an alternative for conventionally used plastic-based food wrappers.
