ABSTRACT:
The novel vacuum sealer of this invention has three wires that are heated to varying degrees. Two wires are used or dedicated to sealing a plastic bag and one of the wires is used to cut the bag after the vacuum sealing step. The vacuum sealer is tapered downwardly, i.e. has a low profile, for a better air flow during the vacuuming step. A turbine with curved fins is used to increase the air flow and reduce the time to evacuate air from the bag. Also, the low profile of the unit, the increased size air ducts and the curved fins on the turbine, provide a more effective system for evacuating air from the plastic bag to be used.
