ABSTRACT:
A method of forming a plurality of easy to open handle bags including the steps of providing a flattened tube of thermoplastic material oriented in a generally longitudinal direction. The flattened tube has a first longitudinal side edge and a second longitudinal side edge, a transverse lower heat seal, and a transverse upper heat seal. The tube also has first, second, and third sections. The second section being disposed between the first and third sections. The first section is joined to the second section along a generally longitudinal first fold line. The second section is joined to the third section along a generally longitudinal second fold line. The second section is cut along a generally transverse first cut line extending between the first and second fold lines. The first section is folded over the second section along the first fold line. The third section is folded over the previously folded-over first section along the second fold line such that the first, second, and third sections overlap one another. The overlapped first, second, and third sections are cut along a generally longitudinal second cut line that intersects the first cut line, the first fold line, and the second side edge at one end and intersects the upper heat seal at the other end. The overlapped first, second, and third sections are then cut along a generally longitudinal third cut line that intersects the first cut line, the second fold line, and the first side edge at one end and intersects the upper heat seal at the other end.
