Abstract: There are disclosed methods of making drinking pouches constructed from at least two panels of flexible laminate web material, at least a first panel thereof having a structural layer (21), a barrier layer (22) and a sealant layer (23), the sealant layer having a first thickness. An exemplary method comprises the steps of punching a hole (19) through the first panel, extruding molten sealant onto the sealant layer (24), thereby occluding the hole, colling the first panel and joining the panels together to thereby form a drinking pouch.

Abstract: 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.
