Abstract

A flat-bottom bag is provided having a folded bottom. Improved adhesive patterns are provided on the bag prior to folding. A first adhesive is provided in a plurality of parallel lines interiorly disposed in a bottom end of the bag. The lines are arranged on front and rear walls parallel to the side walls so that one outer line is positioned on each side of the front and rear walls with corresponding inner lines positioned so that when the sides are folded inwardly, each outer line intersects and contacts one respective inner line in an overlapping manner. This arrangement provides a securing of all interior edges of the folded bottom. A second adhesive can be applied to the exterior of the bag to bond front and rear flap extensions to each other and to the folded sides, forming the flat bottom. In an embodiment, an outer bottom flap is formed by slits in the front flap extension.
