International Classification:

B65D 33/16
B65B 7/02

US Classification:

383210, 53480, 383 611

Abstract:

A reclosable package comprises a first panel having first and second side sections and a second panel having first and second side sections. The first panel opposes the second panel and is joined to the second panel along the first and second side sections. A bottom extends between the first and second side sections of the first and second panels with the first and second panels joined to each other. A mouth is disposed opposite the bottom and extends between the first and second side sections of the first second panels. A closure member extends along the mouth, with the closure member including a first fin joined to the first panel and second fin joined to the second panel. A sealing member having a first and second ends is disposed proximate the mouth. The ends of the sealing member can be attached to the fin or panel such that at least one of the first end or second ends of the sealing member is attached with peelable seal.

International Classification:

B65D 3310

US Classification:

383 8

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.
