Custom Auto Lock Bottom Boxes
Pop. Lock. Load.
Auto lock bottom boxes are folding cartons with a pre-glued bottom that’s sealed during manufacturing, creating a strong base and quick setup. Just squeeze the corners and the box squares up with a satisfying click—no bottom tuck to deal with.
On fast-paced fulfillment lines, eliminating that step saves valuable time and cost, and this style works with many automatic packaging machines.
Strength for Heavier Products
The reinforced, glued base can hold more weight than standard tuck end boxes, so there’s no risk of the bottom popping open. This strength makes them ideal for heavier retail products like glass jars, bottles, electronics, cosmetics, and other premium packaged goods.

Easy Assembly and Added Security
Assembly is simple: squeeze the sides to pop open and lock the base, add your product, then close the tuck top. No taping or extra fastening is required.
The quick setup saves time, while the secure base keeps products protected from packing through retail display. For added security, postal locks can be added to the tuck top lid to keep it securely closed.
Why choose auto lock bottom boxes?
They combine speed, strength, and reliability—making them one of the best options when you need a printed carton that handles heavier loads while still looking good on a retail shelf.
