ABSTRACT:
A method of forming a plurality of easy to open handle bags is provided. The method includes providing a flattened tube of thermoplastic material oriented in a generally longitudinal direction. The flattened tube has a first longitudinal side edge, a second longitudinal side edge, and a transverse heat seal. The tube has first, second, and third sections. The second section is 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. A generally rectangular hole is cut through the second section. The generally rectangular hole has a top edge and a bottom edge. The generally rectangular hole is contained transversely between the first and second fold lines. The tube is then Z-folded such that the second section is folded over the third section along the second fold line and the first section is folded over the folded second and third sections along the first fold line. As a result, the first, second, and third sections overlap one another. A line of weakness is formed adjacent the heat seal. The overlapped first, second, and third sections are cut along a first cut line that intersects the line of weakness, extends therefrom past the bottom edge of the generally rectangular hole, and intersects the first fold line. The overlapped first, second, and third sections are also cut along a second cut line that intersects the line of weakness, extends therefrom past the bottom edge of the generally rectangular hole, and intersects the second fold line.
