Abstract: The present invention discloses a vacuum bag sealing machine used for vacuumizing and sealing plastic bag containing food or the like therein so as to keep the food or the like fresh. The vacuum bag sealing machine comprises a main body consisted of a top cover and a base connected pivotally with the top cover; a static sealing unit including an upper and a lower sealing strip which are disposed on the front portion of the main body, the lower sealing strip being provided with a predetermined number of through holes; a vacuum generating unit including a vacuum pump and an exhaust tubule mounted on the base, the vacuum pump being communicated with the predetermined number of through holes formed in the lower sealing strip through the exhaust tubule; and a heating and opening-sealing unit. The vacuum bag sealing machine is improved in the static sealing unit and the vacuum generating unit, so that it has an increased sealing reliability and a quickened vacuumizing speed.
