A heat-sealed squeezable dispensing pouch comprising: an outer sheet having a front wall, a rear wall and a folded edge located between the front wall and the rear wall, wherein the outer sheet is folded along the folded edge such that an inner surface of the front wall faces an inner surface of the rear wall; one or more heat seals (22, 24 and/or 26) coupling the inner surface of a peripheral section of the front wall to a peripheral section of the inner surface of the rear wall such that the inner surfaces (50 and 52) of the front and rear walls (14 and 16) define an interior cavity; a rupturable inner membrane formed from a contiguous, single monolayer of thermoplastic material, the rupturable inner membrane located within the interior cavity, wherein the rupturable inner membrane divides the interior cavity into a contents chamber and a dispensing passage, wherein the one or more heat seals (22, 24, and/or 26) define an edge of the contents chamber and the folded edge defines an edge of the dispensing passage; a front heat seal coupling the rupturable inner membrane to the inner surface of the front wall; a rear heat seal coupling the rupturable inner membrane to the inner surface of the rear wall; and a score line formed in both the front and rear walls, between the folded edge and the rupturable inner membrane, the score line configured such that the portion of the outer sheet between the score line and the folded edge can be removed to create a dispensing opening in the dispensing passage; wherein the rupturable inner membrane is configured to break when the pressure within the contents chamber is greater than a rupture threshold, wherein the one or more heat seals (22, 24, and/or 26), the front heat seal and the rear heat seal are configured to remain sealed when the inner membrane breaks; characterized in that the outer sheet is made from a multilayer supported film material, wherein at least one of the outer layers of the multilayer supported film material is a strengthened supporting material, wherein said at least one of the outer layers is a foil material or a nylon material. an outer sheet having a front wall, a rear wall and a folded edge located between the front wall and the rear wall, wherein the outer sheet is folded along the folded edge such that an inner surface of the front wall faces an inner surface of the rear wall; one or more heat seals (22, 24 and/or 26) coupling the inner surface of a peripheral section of the front wall to a peripheral section of the inner surface of the rear wall such that the inner surfaces (50 and 52) of the front and rear walls (14 and 16) define an interior cavity; a rupturable inner membrane formed from a contiguous, single monolayer of thermoplastic material, the rupturable inner membrane located within the interior cavity, wherein the rupturable inner membrane divides the interior cavity into a contents chamber and a dispensing passage, wherein the one or more heat seals (22, 24, and/or 26) define an edge of the contents chamber and the folded edge defines an edge of the dispensing passage; a front heat seal coupling the rupturable inner membrane to the inner surface of the front wall; a rear heat seal coupling the rupturable inner membrane to the inner surface of the rear wall; and a score line formed in both the front and rear walls, between the folded edge and the rupturable inner membrane, the score line configured such that the portion of the outer sheet between the score line and the folded edge can be removed to create a dispensing opening in the dispensing passage; wherein the rupturable inner membrane is configured to break when the pressure within the contents chamber is greater than a rupture threshold, wherein the one or more heat seals (22, 24, and/or 26), the front heat seal and the rear heat seal are configured to remain sealed when the inner membrane breaks; characterized in that the outer sheet is made from a multilayer supported film material, wherein at least one of the outer layers of the multilayer supported film material is a strengthened supporting material, wherein said at least one of the outer layers is a foil material or a nylon material.
