Steam Valve Packaging

Manufacturers and packagers of home-heated foods can now provide hermetically-sealed protection against contaminants and more accurately regulate the in-home cooking process with a new steam valve system. The 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 system can be used in both microwave and oven applications.
