The work aims to study the physical and fresh-keeping performances of polyethylene (PE) films modified by clove essential oil and other antibacterial and antioxidant agents. PE resin was modified by clove essential oil, ethylene diamine tetraacetic acid (EDTA-2Na) and vitamin E. The corresponding performances of the formed modified PE films were tested and analyzed. The clove essential oil had better antibacterial effect, with the best mass fraction of 5%. With vitamin E and compound EDTA-2Na as antioxidant agents, when the mass fractions of vitamin E and EDTA-2Na were respectively 2% and 1%, good oxidation resistance results were obtained. The addition of essential oil and antioxidant agent improved the rigidity and barrier property of PE film. The PE films modified by clove essential oil, vitamin E and EDTA-2Na have certain antibacterial activity and inoxidizability, and their barrier property of vapor and oxygen is also improved. The PE films modified by clove essential oil, vitamin E and EDTA-2Na (with respective mass fractions of 5%, 2% and 1%) can effectively prolong the shelf life of strawberries.
