An end-seal patch bag has a patch which extends more than 50 percent of the total transverse distance around the bag, the patch covering at least a portion of at least one side edge of the bag. A side-seal patch bag has a patch which extends more than 50 percent of the total longitudinal distance around the bag, the patch covering at least a portion of the bottom edge of the bag. For both end-seal and side-seal patch bags, the patch covers at least a portion of each lay-flat side of the bag. The invention includes a process for making these end-seal and side-seal patch bags, as well as packaged products utilizing these patch bags. By providing a patch which covers more than just one lay-flat side of the bag, the use of a second patch can be avoided, together with the inefficiency, alignment, and registration challenges encountered if more than one patch is applied to the bag.
An end-seal patch bag comprising a seamless tubular bag having an open top, a first side edge, a second side edge, a bottom edge, an end seal, and a patch adhered to an outside surface of the bag, wherein the patch extends across more than 50 percent of a total transverse cross-sectional surface of the bag, and the patch has a length less than a length of the bag.
A side-sea patch bag comprising a tubular bag having an open top, a seamless bottom edge, a first side seal, and a second side seal, the tubular bag having a patch adhered to an outside surface thereof, the patch covering at least a portion of the bottom edge of the bag, the patch extending across more than 50 percent of a total longitudinal cross sectional surface of the bag.
