ABSTRACT:
A flexible container formed by sealing at least two webs of material with respect to each other to form a void between the webs. Each web preferably has at least two layers. A first web has a first thickness, and a closure area. In at least a portion of the closure area, the first web has a second thickness which is less than the first thickness. A void opening formed in the first web at the closure area provides access to the void. A layer of adhesive is applied to the first web at the closure area to provide for a leak-proof seal at the closure area when the flexible container is folded with respect to the void opening.
