Recloseable retort pouch

A retort pouch, for holding wet content food, said pouch comprising at least two opposed sheets of retort-resistant laminate material, each sheet constructed of a plurality of layers, including an outermost polyester layer, a barrier film layer, a burst-resistant layer and an innermost layer for heat sealing,

• said sheets being heat-sealed together along the outer edges thereof, said sheets each being provided with a laser score line on the inner surface of said burst-resistant layer while said innermost heat sealing layer remains intact preventing the penetration of food into the laminate material so as to preserve shelf-life, without detrimentally affecting the mechanical properties of said pouch, said score lines being opposed to and in registration with one another and parallel with one of said outer edges for easy tearing of the pouch along said score lines,
• said pouch being burst-resistant to retort processing when filled with wet contents and sealed.

A stand-up retort pouch, for holding wet content food, said pouch comprising at least two opposed sheets of retort-resistant laminate material and a bottom gusset, each sheet constructed of a plurality of layers, including an outermost polyester layer, a barrier film layer, a burst-resistant layer and an innermost layer for heat sealing, and further having a recloseable fastener between said opposing sheet surfaces thereof, said recloseable fastener extending from a first side outer edge to an opposing second side outer edge and adjacent to at least one outer edge, said sheet surfaces each having a laser score line on the inner surface of said burst-resistant layer while said innermost heat sealing layer remains intact preventing the penetration of food into the laminate material so as to preserve shelf-life, without detrimentally affecting the mechanical properties of said pouch, said laser score lines provided in registration with one another and parallel with said recloseable fastener, said sheets being heat-sealed together along the top and side outer edges thereof and together with said gusset at a bottom edge thereof, said pouch being burst-resistant when sealed after first being filled with wet contents and subsequently being subjected to retort processing.
