Snap-lock bottom (1-2-3 bottom) Box Template Generator

Snap-lock bottom (1-2-3 bottom). The base panels interlock by hand in three moves — no glue anywhere. Cheaper tooling than an auto-bottom and it ships completely flat, at the cost of a few seconds per box at packing.

Not yet plate-checked. This template folds, closes and exports cleanly, but its blank has not yet been matched against the standard's own drawing in detail. Treat it as a starting point and check it before you spend anything.

What is Snap-lock bottom (1-2-3 bottom)?

Snap-lock bottom (1-2-3 bottom) is a folding carton with a glued side seam, closing at each end with a tuck, a lock or a glued flap. The base panels interlock by hand in three moves — no glue anywhere. Cheaper tooling than an auto-bottom and it ships completely flat, at the cost of a few seconds per box at packing.

Uses

High-volume packing lines, since a pre-glued blank erects in one movement

Advantages

Cut from a single blank, so there is one tool and one part to stock
Arrives glued and flat, and erects quickly by hand or by machine

Disadvantages

The glued joint sets the minimum order — short runs are rarely economical

Typical industries

Food service and takeaway

Recommended board grades

Folding boxboard or solid bleached board, typically 250–450 microns. Heavier board for larger cartons, lighter where the carton is filled by machine.

A55.20.01.03 was claimed here. The plate draws the tuck off the THIRD panel from the glue seam, not the first: the tongue's fold line sits wholly over panel 3 and the lid hinge starts at panel 2, so panel 1 carries no top flap at all. That is the tuck-to-front variant, which this library already has as SNAP-F, so the code lives there and not here. The code's own last pair says the same thing (03), read the way RTE's A20.20.03.01 and RTE-INV's A20.20.01.03 are.

The generator draws this style to whatever dimensions you enter and exports it as a 1:1 PDF, an SVG, or a DXF with the cut, crease and perforation lines on separate layers. Nothing to sign up for.
