Box Structure Guide
An auto-lock bottom box is a folding carton with a pre-glued base that locks into shape as the carton is opened. It improves packing speed and gives the bottom more support than a basic tuck-bottom structure.
Structure Overview
The carton is delivered flat with the bottom panels already glued in a lock pattern. When the packer squares up the box, the base snaps into position, creating a faster setup and a more stable platform for products with extra weight or point load.
Typical Applications
Customization Notes
Use this structure when labor speed and bottom strength matter. Check product weight, board grade, glue tolerance, crease accuracy, and whether the top closure should be tuck top, windowed, or paired with a display-friendly front panel.
