<p>There is provided machinery and a method for manufacturing a stand-up retort pouch (10). The pouch has at least two opposed sheets (12, 14) of retort-resistant laminate material and a bottom gusset (16). 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 (24). 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.</p> |
