What is Full crash lock base, open top?

Full crash lock base, open top is a folding carton with a glued side seam, closing at each end with a tuck, a lock or a glued flap. The crash lock taken right across the base so the whole floor is doubled, with the top left open.

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

Retail display

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.

ECMA 2022 code derived from the published coding rules. The code is printed as a plate and its panel positions are 00, so there is no ambiguity. The BASE was not claimed to match in detail while this file drew the full crash lock as four sheared trapezoids each taken to the carton depth. p.30 takes one base panel — the third from the glue seam — to the full carton depth and leaves the other three at half of it, with a 45-degree gusset crease on the two side panels, and that is what fullLockBottom now draws. The whole blank scores 0.928, up from 0.793.
