A wire frame plastic bag dispenser includes an angled lower bag roll support urging perforated, rolled plastic bags toward a bag roll restraining element attached to the frame. A constraining movement element prevents lateral movement of the bag roll. A perforation parting means separates bags as they are pulled from the roll. The bags may be folded along at least one vertical axis to form a more compact bag roll and may have a chisel cut in the perforation to aid in separation by the perforation parting means. The frame includes four corners each of approximately 90 degrees, has a C shape in a horizontal plane, and includes a dispensing end, a back end, and two sides. The lower bag roll support includes a proximal end attached to the back end and extends downwardly to a distal end. The perforation parting means may be located outwardly from the dispensing end of the frame.
