Auto-bottom (crash lock) carton Box Template Generator
Auto-bottom (crash lock) carton. The base is pre-glued with diagonal creases, so the carton springs into shape the moment you square it up — no assembly, no tape. Worth the extra tooling as soon as you are packing any real volume.
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 Auto-bottom (crash lock) carton?
Auto-bottom (crash lock) carton is a folding carton with a glued side seam, closing at each end with a tuck, a lock or a glued flap. The base is pre-glued with diagonal creases, so the carton springs into shape the moment you square it up — no assembly, no tape. Worth the extra tooling as soon as you are packing any real volume.
Uses
- Retail and gift packaging, where the box is seen by the customer
- 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
- General packing and light manufacturing
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.

A60.20.00.03 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 AUTO-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.
