Reducing respiratory intensity of fruits can effectively prolong their postharvest storage time. In this work, Cu 3 (BTC) 2 /PVC mixed matrix membrane (MMM) have been synthesized via a facile method and used for pomegranate seeds storage. Structural and properties of the Cu 3 (BTC) 2 /PVC MMM were investigated. Results revealed that Cu 3 (BTC) 2 /PVC MMM exhibit enhanced moisture permeability, hydrophilicity, and CO 2 permeability relative to the PVC membrane. Meanwhile, CO 2 /O 2 selection coefficient of Cu 3 (BTC) 2 /PVC MMM was higher than PVC membrane because that CO 2 permeability was improved. Based on these results, weight loss of pomegranate seeds packed with Cu 3 (BTC) 2 /PVC MMM was reduced by inhibiting respiratory intensity. Meanwhile, Cu 3 (BTC) 2 /PVC MMM hindered the decline of total phenol content and nutrient content. We believe that our strategy demonstrate here paves the way to the design and synthesis of novel MMM for the preservation of fresh fruits and vegetables. Practical Applications Mixed matrix membrane has been recognized widely used in fruits and vegetables preservation. The effect of Cu 3 (BTC) 2 /PVC MMM on prolonging the storage time of pomegranate seeds was investigated. The moisture permeability and gas permeability of Cu 3 (BTC) 2 /PVC MMM were studied in detail. Cu 3 (BTC) 2 /PVC MMMs can effectively reduce respiratory intensity of pomegranate seeds, which helps to prolong the storage time of pomegranate seeds. The information of this study would help in the harvest preservation of pomegranate seeds, in order to make them fresh for a long time.
