Journal of Applied Polymer Science, EarlyView.PVC and PVA polymer blends are studied as a function of frequency at room temperature to find the composition that gives the AC conductivity. The blend that has 75% PVC and 25% PVA is chosen as the matrix. Then 10% ZnO nanoparticles are added for food packaging. The change, in conductivity is used as a sign of activity and food freshness. ABSTRACT This
