Steam valve

The pressure-sensitive Flexis Steam valve can be applied to most flexible food packaging, lidding films or molded containers for the purpose of steaming or cooking convenience food in a microwave or oven. The valve's hermetic seal initially protects the contents of the product and becomes self venting during the cooking process, the company says. Developed in partnership with Avery Dennison, the technology also regulates a gradual temperature balance throughout the cooking process to maintain food quality.
