ECMA B40.22.00.00.A
Four-Corner Glued Tray — Variant A. A tray cut without a longitudinal glue seam: a single-wall tray glued at its four corners, closed by corner flaps glued inside the end walls.

STRUCTURE NOTES
About this construction.
Reading the code B40.22.00.00
B40.22.00.00 sits in ECMA group B: non-long-seam-glued folding cartons with rectangular surfaces — tray-style constructions that lock together without a glued long seam, with all outer panels meeting at right angles. The code's blocks describe, in order, the basic tray shape (40), the flap locking system (22), the dust flaps (00) and the cover system (00).
This design's tray shape is recorded as 40, with flap locking system 22; no cover system is coded, so the design works as an open tray.
Group B designs can serve as a single tray or, paired with a matching lid, as a telescopic packaging system.
This template is catalogue variant A of the coded construction, with adjusted proportions.
Typical uses
Unglued tray constructions are erected at the point of use without adhesive: food and bakery trays, counter and display trays, and — with a lid — telescoping gift and presentation boxes. Because they lock by geometry, they store and ship flat and assemble by hand in seconds.
Dimensions and board
The parameters above — length, width, depth and paper thickness — drive the whole blank. Board caliper is not a footnote: tuck clearances, lock engagement and panel fit all scale with it, which is why it is a first-class input to the parametric model rather than an allowance you add by hand.
Every value is validated against the template's supported range, and the 2D dieline and 3D fold preview regenerate together from the same structure. Confirm final board grade, grain direction and tolerances with your converter before production.
COMMON QUESTIONS
Quick answers about this template.
What is Presentation Tray — Four-Corner Glued Tray, In-Fold (Variant A)?
ECMA B40.22.00.00 is an unglued tray-style folding carton in ECMA group B: with tray shape recorded as 40, used as an open tray. This template is catalogue variant A of the construction.
Which dimensions does the Presentation Tray — Four-Corner Glued Tray, In-Fold (Variant A) dieline need?
4 parameters drive the blank: L (length), W (width), D (depth), Paper thickness (mm, µm). Each value is validated against the template's supported range, and the whole dieline regenerates from them.
Can I see how Presentation Tray — Four-Corner Glued Tray, In-Fold (Variant A) folds before cutting it?
Yes. The interactive 3D fold preview and the 2D dieline are generated from the same parametric structure, so the fold you watch on screen is the geometry of the sheet you cut. Open the template in the preview studio to fold it at your own dimensions.
