A tuck end box is built from a cut-and-scored paperboard blank. Its main panels form the front, back, and sides, while a narrow glue flap joins one side seam. At the open ends, hinged top and bottom flaps fold inward to close the pack. Small dust flaps cover the side gaps and help keep the contents from shifting. The locking tuck flap usually slips inside the front or back panel. That sounds simple. It isn’t always.
Boxes are commonly classified by which panel receives the tuck flap. In a reverse tuck style, the top and bottom flaps fold in opposite directions; in a straight tuck style, they fold toward the same panel. This choice affects how the blank is laid out and how the box looks on a shelf. Designers may also describe a box by its bottom closure, such as a tuck-in bottom or a reinforced auto-lock base. These terms can vary between suppliers, so check the actual dieline rather than relying on a label alone. Board thickness, product weight, and flap clearance all matter. A flap that looks secure on screen may spring open after repeated handling. A physical sample is useful, though it can still miss problems caused by a tighter production tolerance.
