  • Bag with Structure for Avoiding Bricking Appearance
    Publication number: 20110299798
    Abstract: A bag structure has a hermetically sealed bag with an outer ply sealed to the bag to define a cavity. The cavity is bounded on one side by a part of the bag and bounded on another side by the outer ply. Perforations are formed through the outer ply to permit passage of gas from the atmosphere into and out of the cavity to reduce unsightly bricking. A one-way valve is formed in the hermetically sealed bag to permit passage of gas from the interior of the bag.
