Auto-Bottom Box with Slotted Top

Yes. While the bottom locks automatically without tape, the top features standard slotted flaps that must be sealed with packing tape or glue before transit.

The dual-layer interlocking floor is secure for most consumer goods and e-commerce payloads. However, extremely dense, heavy point-loads can cause the center interlock to slip. Heavy industrial parts usually require physical drop testing or a switch to a fully taped bottom.

It requires careful validation. Heavy double-wall board makes the diagonal creases stiff, which drastically increases the physical force your packers need to open the box. It also increases the risk of the base tabs binding.

The crash-lock base requires a flatbed die-cutter and a multi-point folder-gluer. Manual prototype gluing will not perfectly simulate the crush and fold behavior of a factory folder-gluer.

It eliminates the steps of squaring the box, folding four bottom flaps, and applying bottom tape. For high-volume lines, saving those seconds on every single unit significantly increases daily throughput.

While it is designed for rapid hand-assembly, running it through an automated carton erector requires specific machinery capable of popping crash-locks. It cannot be run on a standard RSC erector.

The boxes ship completely flat. The glued side seam and folded base add a slight thickness to one side of the knocked-down bundle, but they still stack efficiently on pallets.

Dense point-loads stress the interlocking tabs. If you are shipping heavy, concentrated items, you may need a bottom pad to distribute the weight or a switch to a fully taped bottom box.
