A new steam valve has a proprietary design that provides a hermetic seal when applied over a precut hole in flexible packaging or film lidding. During the cooking process, the valve opens at a predetermined temperature and allows steam to escape by exposing the structure’s slit or perforated baffle layer. The co. claims that the valve can be used in both microwave and conventional oven applications.
