A vacuum-packing machine for sucking the excess air from a wrapping bag containing granular substances and others, creating a vacuum inside the wrapping bag. The wrapping bag is placed on a base, and holes are made on the wrapping bag through a sucking hole by a puncturing device. The air inside the wrapping bag is then sucked by an air sucking device, after which, a piston moves, and a seal adhering to the surface of a sponge on top of the piston seals the holes on the wrapping bag. The seal is supplied to the sponge by a seal supplying device. An air blowing pipe is provided to facilitate the peeling off of the seal from a tape containing the seals.
