Wrap Around Blank
A wrap-around blank is formed into a box by folding it tightly around a rigid product. The positioning of the product, folding and sealing are performed by automatic equipment.
The finished box is essentially an RSC, turned on its side so that the bottom and top are unbroken. The joint, however, is not formed until the final closure. |

A single cut and scored piece features a fifth panel used as the closing flap, completely covering a side panel. The closed box has several layers of combined board on each end, providing stacking strength and protection for long articles of small diameter which might be damage the box, if pushed through the ends. |
