Flared wrap-around, windowed Box Template Generator

Flared wrap-around, windowed. The flared wrap with a pair of tapered apertures cut into each side wall, so the product shows through and the pack is lighter. Locked by a slot beside each top fold.

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 Flared wrap-around, windowed?

Flared wrap-around, windowed is a rigid or lined folding carton. The flared wrap with a pair of tapered apertures cut into each side wall, so the product shows through and the pack is lighter. Locked by a slot beside each top fold.

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

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.

Scored against the ECMA 2022 plate on page 61 with scripts/plate-diff.py: 1.000, MATCH (cut 1.000/1.000, crease 1.000/1.000). Same body as E14.20 — the two differ, measured segment by segment, in that this plate leaves the fold unbroken and cuts a 2.805-deep slot beside it where E14.20 cuts the joint apart over a 1.402 step, rounds the glue lap on 1.406 rather than 2.807, and pierces each wall with two apertures inset a quarter of the wall width from both folds.
