Steam valve regulates prepared food heating
December 14, 2010
Manufacturers and packagers of refrigerated or frozen foods can provide hermetically sealed protection against contaminants and more accurately regulate the in-home cooking process with a unique one-way steam valve system from Avery Dennison.
The Flexis 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. Flexis can be used in both microwave and conventional oven applications.
The steam valves are transparent, offer excellent contact clarity and can be printed with text, graphics and logos in one color. The company claims that the technology provides a hermetic seal and permits the use of thinner films versus microperforated materials.
