PROBLEM TO BE SOLVED: To achieve simplification and automation in the production of a cushioning packaging box by integrally covering an article to be packaged loaded in a container made of corrugated cardboard or the like with a heat- shrinkable film to thermally shrink the film to fix the article to be packed to the bottom surface of the container. SOLUTION: One end of a heat-shrinkable plastic film 14 wound around a roll is sucked to the suction perforated belt 17 engaged with a vacuum tank 6 in a freely revolvable manner to be pressed and bonded to the blank coated with an adhesive sent to the lower part of the tank so as to leave the flap part thereof and, thereafter, the cutting processing of upper and lower flap parts or the like is performed. |
