It is risky without modifications. The tongue locks can pop open during tumbling, and the perforations can burst if the box is dropped. It performs much better on wrapped pallets.

It depends entirely on the board and the perforation rule. Fine flutes tear crisply. Heavy flutes tend to leave jagged paper fibers. We recommend testing a physical sample to check the tear quality before a full production run.

Natively, no. The top and bottom flaps use friction-fit tongue locks. However, engaging those locks takes manual labor per box, and some packers choose to add a single strip of tape for extra security.

The front lip needs to be high enough to keep the front row of products from falling out, but low enough that shoppers can easily grab the items. The perforation line dictates this height.

The continuous perforation line and the precise tongue locks require flatbed die-cutting. A standard shipping box can be made on faster, simpler rotary equipment.
