Auto-Bottom (Auto-Lock) Carton — Common Questions
Why does auto-bottom carry more weight?
The interlocking base panels distribute load across four glued contact points instead of relying on tuck friction — the same reason cereal and heavier cosmetics use it.
Does it slow packing?
The opposite — squeeze the sides and the base pops open flat for one-hand filling. Fulfillment teams usually prefer it to hand-folding tuck bases.
