Abstract:
A method of manufacturing a reclosable bag for filling with at least one food product said reclosable bag comprising:at least one sheet of web material including a first area of structural weakness and a second area of structural weakness; said sheet of web material including at least one fold structure located between and defined by said first and second areas of structural weakness, and a fill opening; said sheet of web material including a first panel coupled to said fold structure adjacent said first area of structural weakness and a second panel coupled to said fold structure adjacent said second area of structural weakness; a reclosable fastener structure including a male track structure and a female track structure; said male track structure including a first skirt structure of web material extending therefrom and said female track structure including a second skirt structure of web material extending therefrom; each said skirt structure including a predetermined coupling portion; said coupling portion of said first skirt structure being coupled to said first panel and said coupling portion of said second skirt structure being coupled to said second panel; said reclosable fastener structure extending past said areas of structural weakness and into said fold structure; said areas of structural weakness being located on said material between said reclosable fastener structure and said coupling portions; said reclosable bag capable of being filled with at least one food product through said fill opening, said method comprising: providing a sheet of web material having a first area of structural weakness and a second area of structural weakness; folding said sheet of web material along a predetermined folding area located between said areas of structural weakness to form said fold structure and said fill opening; providing a reclosable fastener having at least one skirt structure including a predetermined coupling portion; inserting said reclosable fastener into said fold structure and locating said reclosable fastener at a position between said areas of structural weakness and said folding area; coupling said predetermined coupling portion of said at least one integral skirt structure to a location on said web material on the side of the structural weakness opposite said fold area; sealing said web material along at least two predetermined linear areas located generally perpendicular to said fold structure; filling said reclosable bag with at least one food product through said opening; and sealing said opening.
