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 closure device providing a visual confirmation of occlusion. The closure device includes a first and a second interlocking fastening strips which are arranged to be interlocked over a predetermined length, at least one of the fastening strips having a surface alteration providing visual confirmation of occlusion of the closure device. The surface alteration may be a slit which opens or closes upon occlusion of said closure device. In one embodiment, the surface alteration may extend into a coextruded portion. The color of the coextruded portion is exposed when the surface alteration is open and hidden when the surface alteration is substantially closed. In another embodiment, the surface alteration may extend into an edge glow material which produces an edge glow effect when the surface alteration is open. In a third embodiment, the surface alteration may extend through an opaque side wall to expose the color of the base.

Abstract: A closure device having first and second fastening strips arranged to be interlocked over a predetermined length is provided. Each of said first and second fastening strips includes first and second closure elements separated by an intermediate area, wherein the first closure element on the first fastening strip is arranged to be interlocked over a predetermined length with the first closure element on the second fastening strip, and the second closure element on the first fastening strip is arranged to be interlocked over a predetermined length with the second closure element on the second fastening strip. Each of the closure elements may be colored with a colorant. For example, the closure elements on one fastening strip may be colored with an opaque pigment, and the intermediate area on that fastening strip may colored with a first translucent pigment.
