PURPOSE: A sealer having vacuum suction device is provided to vacuum-pack a plastic bag by selectively sealing the inside of the plastic bag under vacuum condition. CONSTITUTION: A sealer having vacuum suction device comprises upper and lower packing(11,21), upper and lower bodies(10,20), and an air outflow path(23). The upper and lower packing are formed on the top and bottom surface in track form, respectively in order to mesh with ends of the opened side of a plastic bag. The upper and lower packing have vacuum space parts. A heating bar(12) of a bottom body is formed in the longitudinal direction of the lower part packing in order to thermally seal the open part of the plastic bag on the front side of the lower packing. The air outflow path is formed on the vacuum space part of the upper packing. A press bar(22) of the upper body is formed in the longitudinal direction of the top packing in order to thermally seal the open part of plastic bag.
