Triangular carton, tuck ends Box Template Generator

Triangular carton, tuck ends. The three-sided tube closed by a single triangular lid at each end, folded down from the base wall with a strip either side that tucks inside the two sloping walls. Closes by hand, with no glue at the ends.

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 Triangular carton, tuck ends?

Triangular carton, tuck ends is a sleeve, wrap or slide carton. The three-sided tube closed by a single triangular lid at each end, folded down from the base wall with a strip either side that tucks inside the two sloping walls. Closes by hand, with no glue at the ends.

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.

Measured against the ECMA 2022 p.48 plate with scripts/plate-diff.py. The same three-panel stack as C10.10.10.10 (bands 41.00 / 30.75 / 30.74 on a 76.87 length, glue lap 7.69) but each end closes with ONE triangular panel hinged off the base wall, carrying a 7.68 tuck strip down each of its two free edges; the other two walls are cut square at both ends. CHECK at 0.848 (cut 1.000/1.000, crease 1.000/1.000) and the 0.848 is the silhouette test alone. This note used to blame the plate's rounded strip corners against the chamfers drawn here, and scripts/missmap.py refutes that: ZERO cells of plate ink missed and ZERO cells of ours the plate lacks, which a corner treatment could not manage. Every stroke agrees in both directions and the profile still reports 15 per cent disagreement, because the profile applies its tolerance ALONG the row rather than perpendicular to the edge — on a shallow slope that turns a difference the ink comparison cannot see into one it fails. See the WHERE THIS MEASURE IS UNFAIR note in scripts/shape-fit.mts, which records this code and PYR-SQ as the two it caps. The blank is not what is wrong here, so do not fix it against the score. Not promoted to verified, because a passing score can take a badge away and must never grant one.
