ABSTRACT:
A combined cutting blade and heat bar for use with a vacuum packaging device having a lid for sealing over the cavity of a base is disclosed. The cutting blade and heat bar are connected to one another and movable via a single actuating mechanism mounted to the lid. In use, in one step the combined mechanism is lowered with the heat bar unheated and the cutting element cuts slits in the bag for evacuation of the air. After air evacuation, the combined mechanism is lowered with the heat bar heated, melting the bag closed behind the slitted area of the bag.
