The need for shelf-stable products led to the creation of retorting processes. Retort films and pouches must withstand the rigors of such processes, and maintain package integrity under pressure with temperatures of 250° F for 20-30 minutes. In the past only tin can packaging could withstand such harsh sterilization environments. Today, Maxim FlexPac’s retort films and pouches are designed and manufactured, to maintain product quality and add to your product’s marketability and shelf-appeal.
