Tuck End Auto Bottom
A tuck end auto bottom box combines a tuck-flap top closure with a pre-glued auto-lock base. The bottom snaps into position the moment you push the flat carton open, while the top uses a standard tuck flap for manual closing. This hybrid gives you the speed advantage of auto bottom assembly (20+ boxes per minute) without sacrificing the easy-access opening of a tuck top. The auto bottom handles heavier products like bottled supplements, candle jars, and stacked cosmetics without the base failure risk of a full tuck-flap carton. Production costs sit between a standard tuck box and a full auto-bottom because only the base requires the pre-gluing step. Material range is 300-400gsm SBS or white cardboard. Common applications include nutraceuticals, premium food items, and retail electronics. Cubit produces custom tuck end auto bottom boxes starting at 100 units.
