Choose it when
Choose an auto-lock bottom carton when pack-out speed and bottom support matter more than the lowest flat-carton conversion cost.

Frequently Asked
Questions.
Ask another question What is the difference between an auto-lock bottom box and a tuck carton?
An auto-lock bottom box has a pre-glued base that opens into position during erection, while a standard tuck carton needs more manual bottom assembly. The suitable option depends on product weight, packing speed and budget.
Can auto-bottom cartons hold heavier products?
They can provide stronger bottom support than a basic tuck-end format, but board grade, dimensions, product weight and handling conditions must be tested with the packed product.
Can the Auto-Lock Bottom Carton be customized with a logo?
Yes. The compatible method depends on the structure, paper and artwork. Options may include printing, foil stamping, spot UV, embossing, debossing, labels or coordinated accessories.
Which materials work for a custom Auto-Lock Bottom Carton?
Common directions include sbs paperboard, kraft paperboard, specialty card stock. Final material and thickness are confirmed against product weight, structure and presentation requirements.
