Auto Bottom
An auto bottom box has a pre-glued base that snaps into a rigid, locked position when you push the carton open from its flat-packed state. The factory glues the base flaps during production, so your packing team skips the bottom-folding step entirely. At 20+ boxes per minute compared to 5-8 for manual snap-lock, the speed difference adds up fast on lines processing hundreds of units per hour. The locked base also distributes weight more evenly than tuck flaps, which means fewer bottom blowouts with heavy products like glass bottles, ceramic candles, and stacked items. Auto bottom boxes work with automated filling equipment and cartoning machines. Standard material is 300-450gsm SBS or white cardboard. The per-unit cost is higher than snap-lock because of the pre-gluing step, but the labor savings usually offset that above 500 units per run. Custom auto bottom boxes from Cubit start at 100 units.
