Abstract

A plastic bag (200) includes a mouth which is covered by a closure flap (205). The closure flap (205) may be peeled back in order to open the bag, without damaging the wall of the bag in or at which the mouth is formed. The closure flap (205) is preferably attached to the bag (200) by means of a peelable adhesive (215) and preferably includes lines of weakness (216) along which the closure flap (205) may be torn. Variations of the bag include a base portion which includes a flat area on which the bag may stand stably.
