ABSTRACT:
A cutter-sealer (10) and a method (300) for cutting and sealing layers of film (70) together. The cutter-sealer (10) provides a heated blade (20), part of which moves through sheets of tautly held layers of film (70) into a slot defined by the seal pad (40). The blade's (20) motion is arrested by a set of blade shoulders (26) that press against the layers of film (70) for a period of time, thereby sealing the layers of film (70) together. The method (300) includes cutting layers of film (70) without liquefaction and sealing the newly cut edges of the layers of film (70) together, also without liquefaction of the layers of film (70).
