Four-corner glued tray, hemmed walls Box Template Generator

Four-corner glued tray, hemmed walls. A deep glued tray with a narrow hem folded back on every wall, so the top edge is turned rather than raw all the way round, and a tapered lap at each corner. Deep enough to stand a bottle in and still clean-edged at the rim.

Checked against the plate. This blank has been compared side by side with the drawing in the FEFCO Code, 12th Edition, and matches. That is a statement about the drawing, not a guarantee — always cut and fold a sample before committing to a die.

What is Four-corner glued tray, hemmed walls?

Four-corner glued tray, hemmed walls is a folding carton with a glued side seam, closing at each end with a tuck, a lock or a glued flap. A deep glued tray with a narrow hem folded back on every wall, so the top edge is turned rather than raw all the way round, and a tapered lap at each corner. Deep enough to stand a bottle in and still clean-edged at the rim.

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.

Measures 1.000 against the p41 plate — cut 1.000/1.000, crease 1.000/1.000, silhouette 1.000. It sat at 0.861 until the corner lap was measured rather than assumed. The note here used to blame the hems, saying the two wall pairs were relieved at different angles and that this drew one of them; that was wrong, and it was wrong in a way worth recording, because it sent the next reader at the returns. scripts/missmap.py put 140 cells of OUR ink the plate lacks against only 28 of its we miss, all four of them on the corner laps and none on a hem. The lap edge on p41 runs 23.75 out from the wall and only 2.0 down, a ratio of 0.084 and a relief of under five degrees, where this corner had always cut its free corners back a flat 0.25 of the lap — fourteen degrees. Setting cornerLapTaper to the measured 0.084 took every one of the five numbers to 1.000 at once, which a fitted fudge does not do. The default is untouched, so the twenty-one other codes on this corner are unmoved.
