There is provided machinery and a method for manufacturing a stand-up retort pouch. The pouch has at least two opposed sheets of retort-resistant laminate material and a bottom gusset. It further has a recloseable fastener between the opposing sheet surfaces thereof, the recloseable fastener extending from a first side outer edge to an opposing second side outer edge and adjacent to at least one outer edge. The sheet surfaces are each scored with a laser score line. The laser score lines are in registration with one another and parallel with the recloseable fastener. The sheets are heat-sealed together along the top and side outer edges thereof and together with the gusset at a bottom edge thereof. The disclosed pouch is burst-resistant when sealed after first being filled with wet contents and subsequently being subjected to retort processing.
