Abstract
A flexible package for a product, e.g., a food product, to enable any steam resulting from heating the product in the package to automatically vent is disclosed. The package has a hollow interior space in which the product is located and is made up of a flexible sheet material. Portions of the flexible sheet material are sealed to each other along an elongated seal line, which forms a portion of the periphery of the hollow interior space. A portion of the seal line is in the form of a peelable interface. At least one vent is coupled to the peelable interface. The peelable interface automatically peels open upon the creation of steam within the package resulting from the heating of the product to allow the steam or other vapor to automatically exit through the at least one vent.
