The degradable active antibacterial PLA/PHA films were prepared with 5% tea tree oil and 5% eucalyptus essential oil, respectively by extrusion-casting method. Fresh blueberries were stored at (4±1) ℃ and then packaged in PLA/PHA cling film, tea tree oil/PLA/PHA cling film and eucalyptus oil/PLA/PHA cling film, respectively. The basic properties of the three films were measured. The content of oxygen and carbon dioxide in the bags, decay rate, weight loss rate, firmness, total soluble solids content, total phenol, anthocyanin, and vitamin C content of blueberries were measured every 7 days. The quality of blueberries with different films were compared during storage time. The results showed that the active antibacterial film containing essential oils could effectively reduce the rate of fruit rotting and weight loss of blueberry and delayed the decrease of anthocyanins and vitamin C content of fruits compared with the control group, while maintaining the firmness of fruits. Eucalyptus oil/PLA/PHA cling film packaging is better for maintaining blueberry fruit freshness, reducing fruit moisture evaporation, and maintaining total phenolic content.
