ABSTRACT:
The present invention is a carton having side panels which intersect at beveled edges to provide greater grip stiffness and reduced surface area to volume, and a blank therefor. The blank has vertical score lines which extend along the entire length of the blank at least two of the edges in order to assist in the fabrication of the carton on a form, fill and seal packaging machine. The carton may have a rectangular cross-section, a square cross-section or the like. The carton may have a fitment attached thereto for accessing the product contained therein. The carton may have an overfolded bottom for protection against leakage and wicking.
