An apparatus facilitates folding of a blank to form a box. When the blank is pressed into the apparatus, corner panels of the blank are initially folded by folding surfaces of the apparatus so that the corner panels are disposed inside side panel surfaces of the blank, which are folded by other folding surfaces of the apparatus. The apparatus further includes folding surfaces for folding the side and end panels of the blank into a vertical position. A base panel of the blank, and the side panels, end panels and the corner panels which are attached to the base panel, are received in an interior aperture of the apparatus during folding of the blank to form the box.
