Abstract:
1. A cutter-sealer for cutting and sealing layers of film, said cutter-sealer comprising: a blade for being selectively heated and for cutting and sealing the layers of film, said blade having: a seal pad fabricated of a flexible material, said seal pad defining a seal pad slot adapted for receiving at least a portion of said cutting section of said blade, said seal pad further defining at least a first contact surface proximate said seal pad slot adapted to cooperate with said at least one first blade shoulder to engage the layers of film and press the layers of film together, said seal pad further defining a second contact surface proximate said seal pad slot; a seal pad caddy for carrying said seal pad, wherein said seal pad caddy defines at least a first material fixation surface; and a means for selectively securing the layers of film proximate said seal pad slot, wherein said means for securing the layers of film proximate said seal pad slot includes at least one film clamp adapted to cooperate with said first material fixation surface to engage the layers of film and hold the layers of film tautly across said seal pad slot; whereby after said cutting edge contacts the layers of film to heat and soften the layers of film without liquefying the layers of film, at least a portion of said cutting section of said blade travels through the layers of film and into said seal pad slot, thereby dividing the layers of film and allowing said at least one first blade shoulder to press the layers of divided film against said at least one first contact surface to accomplish sealing of the layers of divided film and whereby at least a portion of the layers of divided film are pressed between said second blade shoulder and said second contact surface to accomplish the sealing of the layers of film.
