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 a band seal at the bottom of the bag. The bottom of the bag is closed. The wicket flap has a line of weakened tear resistance, such as a perforated line, along which the bag can be torn. The bag on top of the stack can be filled through the open zipper with product. After filling, the zipper is closed by operating the slider and then the filled bag is separated from its flap, which remains on the wicket, by tearing along the tear line.
