For folders, one or more pieces of combined board provide an unbroken bottom surface, and are scored to fold around a product. The International Fibreboard Case Code describes them as Folder-Type Boxes. The carrier classifications use the term Folders.
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.
