Tuck Top Auto Lock Bottom.

Auto Lock Bottom.

A tuck top auto lock bottom box, also known as an auto bottom carton, is a heavy duty folding carton box with an automatic locking bottom. Just squeeze and box pops into shape with bottom already locked closed.

As with all tuck top style boxes, the auto bottom box makes a great retail product box –they are easily customized to attract attention, and hang tabs can be added so products can be placed on a hook or clip strip for display anywhere.
