Abstract: Disclosed are a bundle of nozzles for vacuum sealing a plastic bag that are inserted into the plastic bag to form air discharging passages by the coupling to one another and are then heat sealed together with the plastic bag. The bundle of nozzles of this invention include a plurality of nozzles being made of a heat sealable material in order to be inserted into the plastic bag and heat sealed together with the plastic bag, wherein the plural nozzles are coupled to one another along the outer peripheral surfaces thereof, thereby providing the air discharging passages from the plastic bag.

Abstract: Disclosed is a nozzle for vacuum sealing a plastic bag, the nozzle including: an embossing part formed on the peripheral surface of the nozzle, so that air discharging passages are formed on the peripheral surface of the nozzle; and a plurality of break lines formed at predetermined regular intervals on the outer peripheral surface of the nozzle, for cutting the nozzle to a predetermined length, wherein the nozzle is made of a heat sealable material, so that the nozzle cut by the break line is inserted into the plastic bag and heat sealed together with the plastic bag.
