A method of using a plastic bag (10~) for point of sale purchase and a web o f continuously attached length of plural bags (10) along a supply length by a perforated tear line (2). A seal (3) which runs codirectionally with the tea r line (2) forms a closed bottom for each bag (10~), such that when a bag (10) is separated along the tear line (2) from a remainder of the supply, the bag (10~) is enclosed along three of its four edges enabling containment of produce or other items placed therein via the opening at the fourth, and remaining edge of the bag (10~) which is coextensive with the perforation li ne (2). The perforation tear line (2) cuts entirely through the continuous web supply of bags (10), however, the perforation along one side the bag (10~) i s broken, such that the bag 10~) presents an open flap (4) through which contents can be added. |
