FLEXIBLE POUCH WITH PRESSURE RELIEF VALVE

摘要

A flexible pouch that includes a pressure relief valve and an associated barrier seal. The barrier seal separates and partially encloses a portion of the flexible pouch containing the pressure relief valve from a portion of the pouch containing product, such as a liquid. The barrier helps to ensure that only gases are released through the pressure relief valve, and further helps to prevent product from interfering with operation of the pressure relief valve.
