Two-Double-Wall Locking Tray with Lid
ECMA B20.01.00.00 + Lid
A tray cut without a longitudinal glue seam: an unglued tray with two double walls and locks, closed by a claw lock. The catalogue pairs it with a separate lid piece, so tray and lid are generated together as a two-part set.

STRUCTURE NOTES
About this construction.
Reading the code B20.01.00.00
B20.01.00.00 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 (20), the flap locking system (01), the dust flaps (00) and the cover system (00).
This design is an unglued self-locking tray with two double walls, with flap locking system 01; 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 generates the lid component of the construction as its own dieline.
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 Two-Double-Wall Locking Tray with Lid?
ECMA B20.01.00.00 is an unglued tray-style folding carton in ECMA group B: an unglued self-locking tray with two double walls, used as an open tray. This template generates the construction's lid component as its own dieline.
Which dimensions does the Two-Double-Wall Locking Tray with Lid dieline need?
5 parameters drive the blank: L (length), W (width), D (depth), H (height), Paper thickness (mm, um). Each value is validated against the template's supported range, and the whole dieline regenerates from them.
Can I see how Two-Double-Wall Locking Tray with Lid 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.
