Abstract

A novel antimicrobial poly (lactide) (PLA) film incorporated with clove essential oil (0, 2%, 4%, and 6% (w/v)) was developed. The mechanical property, water vapor permeability, color, contact angle, and antimicrobial activity of the films were investigated. The flexibility of films was improved by incorporation with clove. The water vapor permeability slightly increased with clove content. PLA film containing clove showed better antimicrobial activity compared to pure PLA film. The results suggested that PLA/clove blends could be a novel composite film for food packaging applications.
