PROBLEM TO BE SOLVED: To provide the packaging process capable of performing non-hole packaging without having small holes and a ventilation section, preventing foreign matters such as insects from being entrained, and preventing a packaging bag from being damaged and preventing a cargo pile from being collapsed when they are flatly displayed. SOLUTION: Packaged materials are filled in a packaging bag a that is hung and supported with the opening of the bag upwardly positioned with a grip pair g that are intermittently travelled in a plurality of processes, a packaging machine P configured such that heat seal is performed on the opening of the bag after the air in the packaging bag a is removed with a degassing nozzle 10 is employed, and in the forming process (6), a pressure-applying means 15 where a pair of pressure-applying means 21, 27 on which a vibrator 22 is mounted is approachable and separable by the action of the pneumatic cylinder 31 is provided, the packaging bag a in which the packaging materials are packed is vibrated with the vibrator 22 while pressure-applying the same bag with the pressure-applying means 21, 27 from both sides and the front and the rear to stretch the packaged materials in the elevating direction to form the same with a certain thickness and simultaneously remove the air in the same packaging bag with the degassing nozzle 10, thereby performing heat seal thereon.
