Abstract Clove essential oil (CEO) was immobilized in mesoporous silica nanoparticles (MSN) (0, 1, 2, and 3 wt%) and incorporated into poly(lactic acid) (PLA) matrix via a casting method. The functional properties including mechanical property, thermal property, antimicrobial property, and CEO release behavior of the PLA nanocomposite film were investigated. The compatibility of CEO-loading MSN with PLA was verified by scanning electron microscopy analysis. The tensile strength, tensile module, and glass transition temperature of the MSN/CEO/PLA composite film was improved with the increase in MSN content. The release study indicated that the MSN/CEO/PLA composite films exhibited sustained release profile of CEO. The MSN/CEO/PLA films demonstrated efficient antimicrobial activity. The results indicated that CEO immobilized MSN incorporated PLA nanocomposite film showed promising features for active food packaging material.
