摘要：

The study aims to prepare antimicrobial films for food packaging using hydroxyethylcellulose (HEC) biopolymer to decrease environmental problems of synthetic polymer. Different ZnO concentrations (0.05, 0.1, and 0.2 %) were incorporated into HEC. The citric acid (CA) was used as a crosslinker for HEC and the casting method was used to prepare HEC/CA and HEC/CA/ZnO films. The prepared films were characterized by FT-IR, XRD, TGA and SEM. Also, mechanical, wettability and antimicrobial properties were examined. The presence of ZnO particles in the films was confirmed by XRD. SEM showed surface morphological differences between HEC/CA and HEC/CA/ZnO films. HEC/CA/ZnO film inhibited the growth of Staphylococcus aureus (91.4 %) and Escherichia coli (61.7 %) bacteria. Consequently, the prepared films consider a promising material for food packaging application.
