Confectionery & Chocolate Box

Reading the code B48.21.00.00

B48.21.00.00 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 (48), the flap locking system (21), the dust flaps (00) and the cover system (00).

This design is an unglued tray with four double walls and webbed corners, locked with webbed corners locking the double walls; 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.

How the closures behave

All four walls fold up and return on themselves. Each corner is webbed, so the gusset folds inward as the walls rise and locks the pair square without adhesive. The inner wall of each pair is one board thickness shorter than the outer and ends in a chamfered tip that rests on the base, which keeps the double wall flush. No cover system is coded, so the tray stays open.

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.

Industries and applications

Converters cut the Confectionery & Chocolate Box (ECMA B48.21.00.00) for chocolate, praline and confectionery boxes.

Confectioners want a tray that holds the pieces still and a lid that closes again after the first praline.

What is Confectionery & Chocolate Box — Webbed-Corner Tray with Double Walls?

ECMA B48.21.00.00 is an unglued webbed-corner tray with four double walls: every wall folds double, a webbed corner locks each of the four corners, and the inner wall of each pair ends in a chamfered tip resting on the base. Open top, no glue.

Which dimensions does the Confectionery & Chocolate Box — Webbed-Corner Tray with Double Walls 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 Confectionery & Chocolate Box — Webbed-Corner Tray with Double Walls folds before cutting it?

Yes. The interactive 3D fold preview and the 2D dieline are generated from the same parametric model, so the fold you watch on screen is the geometry of the sheet you cut. Open the template in the studio to fold it at your own dimensions; 3D folding comes with the Workshop and Line plans.
