Abstract
A sealed multi-ply bag capable of being resealed including sides, a bottom, and front and back panels. A resealable closure is mounted across the top edges of the front and back panels as the secondary closure. The front and back panels are folded one or more times about the resealable closure to form a primary closure. A sealing flap runs across the folded area to maintain the bag in its sealed, folded configuration. The upper portion of the front panel may be step cut to provide a tighter primary closure.
