This 5 x 3-1/4 x 7-1/4" heavy duty reverse tuck folding carton is constructed from 36-point kraft chipboard — substantially thicker and more rigid than standard folding carton stock — making it well suited to contents that require extra crush resistance and structural support. The reverse tuck closure tucks the top flap to the rear and the bottom flap to the front, creating a secure, self-contained enclosure that stays closed through handling and transit.

The natural kraft finish presents cleanly without printing or coating, making these cartons a practical fit for retail packaging, subscription box inserts, nutraceuticals, hardware components, and any application where a label-ready neutral surface is preferred. The flat-fold format supports fast assembly on high-volume pack lines and compact bulk storage in warehouse environments.

Each case contains 250 cartons. The 36-point board grade is the defining specification here — it provides measurably greater rigidity than the lighter chipboard grades commonly used in folding carton applications, reducing deformation risk for heavier or irregularly weighted contents.
