ABSTRACT:
A tote container which is cut to form a blank from a single sheet of double-faced corrugated plastic material, the blank being scored to define individual panels, and those panels folded to an upright position to define a receptacle region. The corrugations of the plastic material define a grain, and the blank for the tote container is oriented upon the sheet of corrugated plastic material such that the lines of grain cross the scored fold lines separating the panels at an acute angle thereto, thereby permitting individual lines of grain to extend under the receptacle region of the tote container and traverse the tote container both laterally and longitudinally. This prevents the planar plies of the double-faced corrugated plastic sheet material from being perforated, and the convoluted intermediate ply from being crushed along the length thereof, when the blank is scored. The folds between the panels are straighter and do not roll or buckle away from positions of the predetermined scored fold lines, and the planar plies will not fray along the edges of the blank.
