How this flat structure works
A 1-2-3 bottom uses four die-cut bottom flaps that interlock mechanically in three hand steps without bottom glue—giving heavier jars, mugs and bakery items a stronger floor than a standard tuck flap.

Does a 1-2-3 bottom hold heavier items than a tuck bottom?
Yes. Because all four bottom flaps interlock across the center of the floor, a 1-2-3 bottom resists pushing open under dense jars or ceramics better than a single friction tuck.
Can a 1-2-3 bottom be made in corrugated board too?
Yes—both thick paperboard and E-flute corrugated work cleanly with 1-2-3 snap-lock bases.
