Abstract
A reclosable bag having a bottom flap with holes configured to allow a stack of the bags to be mounted on a wicket, a slider-actuated string zipper installed in a mouth at the top of the bag, and an open string zipper, not actuated by a slider, installed at the bottom of the bag. The wicket flap has a line of weakened tear resistance, such as a perforated line, along which the bag can be torn. Product is inserted into the receptacle via the open string zipper, and then that zipper is closed. After filling, the receptacle can be separated from the flap, which remains on the wicket, by tearing along the tear line.
