A flat piece of corrugated fiberboard, which has been cut, slotted and scored, is often referred to as a box blank. For several box styles, in order to convert the box blank into a box, its two ends must be fastened together with tape, staples or adhesives such as water soluble glues. The location at which the two ends meet is known as the manufacturer's joint. There are several variations within the three fastening techniques mentioned with most corrugated box manufacturers following their own protocols for fastening the manufacturer's joints. This study explored the compression and tensile strengths of RSC style corrugated boxes based on adhesive (glue) coverage, three different types of tapes (acrylic, paper and reinforced paper) and application angle of staples. The fabricated boxes were also tested for compression strength and deflection. Test data (N = 10) was collected for each dependent variable of peak force, deflection at peak force and tensile strength using the analysis of variance procedure with a Turkey probability distribution at a 0.05 critical limit. The results suggest an overall higher tensile strength for glue than the other fastening techniques evaluated (P < 0.05) with no significant difference (P > 0.05) for peak force or deflection at peak force for all glued, stapled or taped treatments.
