ABSTRACT:
A sealing and packaging device in which, simultaneously when a sealing base frame lifted upwards from a lower region towards a flange on the perimeter edge of a tray mounted on a desk plate makes contact with the flange, a touching base provided on a frame of the sealing base frame makes contact with the lower surface of the deck plate, and the tray is pushed upwards towards a cover film by means of the deck plate and sealing base frame, the cover film being welded to the flange of the tray. By means of the upward movement of the tray caused by the sealing base frame and deck plate, breaking of the tray is prevented by the deck plate on which the tray is mounted, even when the tensile pressure of the film or the reaction of urethane rubber members act respectively on the packaged item in the tray.
