Abstract
Abstract A package of resealable polymeric bags is formed by stacking the bags formed with a flap having a strip of pressure-sensitive adhesive extending beyond the flap such that the sealing flap of each successive bag is the mounting means for that bag in the package, and each bag is positioned with the open side exposed on the top of the stack to afford easy insertion of an article in the bag, removal of the bag from the stack, a folding and sealing of the flap.
