PURPOSE: A portable air passage generating device of a vacuum packing bag is provided to pack the contents efficiently in the small space with the vacuum packing machine by forming various air discharge passages in the vacuum packing bag made of laminated film at a low cost. CONSTITUTION: A portable air passage generating device of a vacuum packing bag is composed of a base structure(200) having a lower forming plate(210) with the pattern for generating the air passage in the packing bag; a cover structure(300) combined with the base structure by a hinge and composed of an upper forming plate with the pattern corresponding to the lower forming plate; and a control unit controlling power to heat the upper forming plate or the lower forming plate. A housing is formed in the base structure to store the lower forming plate with the pattern for generating the air passage and the control unit.
