These 4 x 4 x 4 inch kraft reverse tuck folding cartons are built from 24-point die-cut fiberboard, delivering consistent rigidity and a uniform cubic format. The reverse tuck configuration closes from opposite ends — top and bottom tuck flaps insert from opposing sides — eliminating the need for tape or additional fasteners at either closure point.

Pye-lock tucks provide positive, self-locking engagement on both ends, keeping cartons securely closed through handling, transit, and shelf display. Compliance with federal specification PPP-B-566 makes these cartons a viable choice for regulated packaging environments including pharmaceutical, cosmetic, and consumer goods distribution.

Each case contains 250 cartons shipped flat, reducing storage footprint on the shelf or pallet. The 24-point fiberboard construction supports stacking without deformation, making these cartons well suited for high-volume packing lines where consistent erection and reliable closure are priorities.
