Abstract A mailing folder for a heavy object such as a book of great thickness is formed from a cut and scored blank of paper board folded into position to provide a pair of opposite protective cells for ends of the book. The folder comprises a plurality of rectangularly shaped panels connected to define a tube, and cell forming elements extend from opposite ends of a main panel thereof and are foldably connected to each other and to the main panel to enclose opposite ends of the book. Each of the cell forming elements comprises first and second spaced outer flap elements foldable to an inclined upright position with an inner flap element foldably connected to the first and second flap elements at a distal flap edge thereof and foldable to a vertical position with the distal edge bearing against the main panel. A central reinforcing element extends between the first and second outer flap elements and is foldably connected at its ends to the main panel and the inner flap element, the central element having first and second portions additionally defined by spaced edges in the first and second outer flap elements and in the main panel, the central reinforcing element being folded upon folding of the first and second outer flap elements to a position where a portion thereof is braced against the first and second spaced flap elements. Closure elements extend from a top panel of the tube and are foldable to a position over the protective cell forming elements to provide a pair of oppositve protective cells for the book contained within the folder.
