The main function of food packaging is to maintain the quality and safety of food products during storage and transportation, and to extend the shelf-life of food products by preventing unfavorable factors or conditions such as oxygen, moisture, light, external force, etc. In order to perform such functions, packaging materials provide physical protection and create proper physicochemical conditions for products that are essential for obtaining a satisfactory shelf life and maintaining food quality and safety. Food packaging is not only used as a container but also acts as a protective barrier with some innovative functions. Recently, the polymer modified silica with mechanical flexibility, good barrier properties, and thermal stability can be used for the variety application. In this work, the PVA modified silica materials with various contents and the other functional groups used to decrease the water vapor transmission rate (WVTR) and the oxygen transmission rate (OTR). |
