ABSTRACT:
A closable pouch is provided with first and second webs secured together partially around an interior portion. Each web has at least one generally straight end edge defining a portion of the pouch opening. An adhesive sealing strip is disposed on the first web parallel with and spaced from the first web one end edge thereby defining a first fold line along the margin of the strip that is parallel to and nearest the first web one end edge and defining a second fold line along a margin of the strip that is parallel to and furthest from the first web one end edge. Folding of the webs together away from the first web about the first fold line, then about the second fold line, and finally about a third fold line in registry with the repositioned first fold line orients the adhesive sealing strip against an adjacent region of the second web to form a closure seal in the pouch.
