Abstract
A patch bag comprises a lay-flat bag having a patch adhered thereto. The bag has an open top, a closed bottom, and first and second closed sides. The bag is made from a bag film having an inside surface which is sealed to itself. The bag film includes a seal impression on its outside surface. The patch is made from a patch film which is adhered to the outside surface of the bag film. The patch covers at least a portion of the seal impression on the outside surface of the bag film. The patch has a smooth, unimpressed outer surface over the seal impression on the bag film. A process for making the patch bag comprises sealing the bag film to itself and thereafter adhering the patch to the bag, with the patch being adhered over the seal impression on the bag film.
