Abstract: A polymer bag dispenser, having a header for receiving a plurality of stacked bags, the header having a leading edge. A plurality of bags is stacked and retained within the header. Each one of the bags has a back panel and a front panel wherein the back panel is longer than the front panel. Each bag includes a lip connected to the bag back panel. A line of perforations is formed in the back panel and the line of perforation is substantially adjacent to, and parallel with, the header leading edge. The line of perforations is created after a stack of bags has been formed in the header. In order to ensure clean separation of a bag from the header and a sharp and uniform edge for lips retained within the header, the line of perforations is disposed at a distance of about 1/4 inch away from the header leading edge. Each one of the panel lips is retained by the header when a bag is separated therefrom, along the line of perforations.
