Confectionery & Chocolate Box

Reading the code B20.05.00.50

B20.05.00.50 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 (05), the dust flaps (00) and the cover system (50).

This design is an unglued self-locking tray with two double walls, locked with lock tabs in the double end walls and interlocking hook ears, closed by a tuck-in flap cover.

Group B designs can serve as a single tray or, paired with a matching lid, as a telescopic packaging system.

How the closures behave

Each end wall folds up and returns on itself; lock tabs on the inner layer drop into slots along the base crease and hold the double wall closed. The side walls carry hook ears that fold around the corners and interlock at mid-width across each end wall, bracing the tray. The lid continues from the back wall and closes with a tuck flap into the front.

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 B20.05.00.50) for chocolate, praline and confectionery boxes and gift boxes and presentation packs.

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

What is Confectionery & Chocolate Box — Tray with Locked Double End Walls, Hook Ears and Tuck Lid?

ECMA B20.05.00.50 is an unglued carton tray with locked double end walls, hook ears and a tuck lid from the same blank. Lock tabs on the inner end-wall layers enter slots in the base crease, and hook ears on the side walls interlock across each end wall.

Which dimensions does the Confectionery & Chocolate Box — Tray with Locked Double End Walls, Hook Ears and Tuck Lid 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 — Tray with Locked Double End Walls, Hook Ears and Tuck Lid 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.
