Abstract: A blank is provided for forming either a packaging structure of a relatively large size or a greater number of smaller sized packaging structures. The blank is provided with predetermined fold lines. Folding the blank along one series of fold lines forms the relatively large packaging structure. Separating the blank along one or more fold lines into plural blanks and folding the plural blanks along another series of fold lines forms multiple smaller packaging structures. A similar technique forms one large or multiple smaller covers for the packaging structures.
