ABSTRACT:
The hermetic packaging apparatus comprises a nozzle for reducing pressure in a thermoplastic packaging bag containing certain contents, the nozzle reduces pressure in the packaging bag by the pressure control of the air pump and the water sucked from the contents is directed to a strainer tank. Thereafter, the nozzle moves backward, the opening of the packaging bag is heated by a heating element, and an airtight pressure connecting bar is pressured downward so that the opening portion is heat-sealed by the airtight pressure connecting bar and the sealing base.
