Abstract: The present invention provides a storage bag including a bag body including two opposing sidewalls, the sidewalls including peripheral edges and the sidewalls being attached together along at least a portion of the peripheral edges. Each of the sidewalls include an outer surface and an inner surface, where the inner surfaces define opposing inner faces, and at least one of the inner faces includes a pressure sensitive composite material. In accordance with another aspect of the invention, a process for forming a storage bag material is provided including the steps of: providing a sheet of base film; providing a pressure sensitive composite material having an adhesive on one side thereof; moving the sheet of base film and the pressure sensitive composite material into overlaying engagement; and attaching the pressure sensitive composite material to the sheet of base film.

Abstract: A storage bag for food products with a venting structure to expel excess air trapped inside the bag after the bag has been closed or sealed. After the excess air is removed, the venting structure is covered and sealed to prevent air from re-entering the bag or other objects from entering the bag.

Abstract: Provided is a valve element for venting fluids, such as gas or liquids, entrapped in a packaging enclosure. The valve element includes a base element having an aperture disposed through it and a membrane having a protruding raised portion. The membrane is attached to and overlays the base element. The raised portion is selectively configurable between a concave position and a convex position by applying an external force against the apex of the raised portion. When configured in the convex position, the raised portion is spaced apart from the aperture allowing fluid communication therethrough. When configured in the concave position, the raised portion obstructs the aperture preventing fluid communication therethrough. To vent air passing through the aperture into the environment, an expandable channel for providing a clearance is provided between the membrane and the base element.
