Mechanical and antibacterial properties of recycled carton paper coated by PS/Ag nanocomposites for packaging

► In this study we prepare Ag nanoparticles by novel method as antibacterial additive. ► Prepared Ag nanoparticles characterize by using XRD, UV and TEM. ► Ag nanoparticles impregnated into PS solution and coated carton by different ratio. ► We find that the coated carton shows good antibacterial and mechanical properties.
