Plastic, paper, aluminum foil, or aluminum foil laminated with plastic bags are dispensed, one at a time, from a bag dispenser. In a first embodiment, bags are provided in rolls, connected top-to-top and bottom-to-bottom. Each bag is tapered towards its bottom such that its top-to-top connection with the next bag is wider than the bottom-to-bottom connection. Each bottom-to-bottom connection has sealed seams, which ensure that the bags are closed at their bottoms, and a row of closely spaced perforations on a connecting portion between two seams, which allow adjacent bags to be separated by pulling and tearing along the row of perforations.In an alternate embodiment of this invention, a plurality of tapered bags is nested with one bag inside the next adjacent bag. The bags are tapered at both sides such that their bottoms are narrower than their tops. At their tops, they are attached to strips of materials that are in turn attached to each other by conventional means such as staples. Rows of closely spaced perforations ensure that each bag is open when a bag is separated from the strips by pulling and tearing along the row of perforations.In a third embodiment the bags are nested and attached to a perforated central tab that passes through the bottom seam of each bag. The nested arrays of bags may be placed in a funnel-like dispenser that holds the nested bags in an upright position.
