Abstract: A flexible container including two webs sealed with respect to each other to form a void between the webs. A first web forms an opening within a closure area. The opening is positioned along a fold line that passes through the closure area. With the flexible container in an unfolded condition, a layer of adhesive is applied to the first web within said closure area. The webs form two notched areas each at or near one of two opposing outer edges of the flexible container. The fold line intersects with the notched areas. With the flexible container in a folded condition, a portion of each web is folded with respect to the opening and a first portion of the adhesive layer on a first side of the opening forms an adhesive-to-adhesive contact with a second portion of the adhesive layer on an opposing second side of the opening.

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. A seal seals a first web with respect to a second web to form the void. At least one portion of the seal is non-linear, preferably having an arcuate shape and bowed outward from the void. The first web defines a closure area which forms an opening to provide 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.
