ABSTRACT:
Process for erecting a folding carton from a single-piece board blank which has a base surface, to which side panels are hinged along folding lines, and a front and back panel, where flaps are provided on the side panels that are folded into the area of the front and back panels, and where at least sections of the blanks are coated with a sealable plastic. First of all the two side panels are erected by pressing the board blank into a U-shaped female tool. Rotating lugs fold in the flaps; the back and front panels are heated up to such an extent that the plastic coating is sealable, after which the back panel and the front panel and the flaps are pressed against each other and are sealed together.
