Abstract
An L-seal patch bag has an open top, a bottom seal, a seal along a first side edge, and a patch covering a seamless second side edge. The bag is preferably made by adhering, at intervals and across a continuous flat film, a plurality of discrete film patches. Each of the patches covers a centerline running the length of the elongate flat film. The resulting laminated article is then folded along its length, preferably at the centerline, making a first seal by sealing the elongate flat film to itself by sealing along a first (open, non-seamless) side edge of the elongate flat film. A second seal is then made by sealing across an entirety of the folded, laminated article, which is thereafter cut across below the second seal, whereby an L-seal patch bag is produced. Analogous processes can be used to produce a side-seal patch bag or a backseamed patch bag. Still another process of making a side-seal patch bag involves folding the elongate flat film transversely before sealing along the side edges and cutting the resulting side-seal bag from the remainder of the elongate flat film.
