The steam valve system uses a proprietary design that provides a hermetic seal when applied over a pre-cut hole in flexible packaging or lidding film. During the cooking process, the valve opens at a predetermined temperature and allows steam to escape by exposing the structure’s slitted or perforated baffle layer. The use of an external valve allows a steam release feature to be added without changing the package’s basic construction.
Steam valves are completely clear and can be printed with text, graphics and logos in one color. Plain or printed steam valves can be pre-applied.
