These 4 x 4 x 6" reverse tuck folding cartons are built from 36-point chipboard, delivering substantially greater rigidity and crush resistance than standard folding carton stock. The natural kraft finish provides a clean, uncoated surface suited to operations that want sturdy, professional-looking packaging without added lamination.

The reverse tuck closure — top tuck opening from the front, bottom tuck opening from the rear — creates a self-locking carton that holds its form under product weight without tape or adhesive in most applications. This makes them practical for retail shelf packaging, e-commerce kit fulfillment, wholesale distribution, and light manufacturing environments where quick, secure hand-packing is a priority.

Cartons are supplied flat-folded in cases of 250, minimizing storage footprint until needed. The 36-point board grade is the defining specification here, distinguishing these from lighter-duty folding carton options where stackability and product protection are primary concerns.
