ABSTRACT:
A method and apparatus for manufacturing a non-rectilinear flexible package comprising an in-line process including application and selective sealing of a semi-rigid strip to an inner wall of the package and further including a dual-stage die-cutting technique to remove and cut a non-linear shape into a formed web of film. The semi-rigid strip is sealed to one interior wall of the package but not the other to provide a reinforced opening to the package through which a material can be dispensed. Additionally, the dual stage die-cutting method comprises first cutting and removing a portion of the web material prior to filling the package and again cutting and removing a portion of the web material after filling, resulting in a package having a narrowed neck adjacent the closed reinforced opening at an upper portion of the package and a body of the package that is tapered towards the reinforced opening.
