ECMA A30.81.03.00

Reading the code A30.81.03.00

A30.81.03.00 sits in ECMA group A: long-seam-glued folding cartons with rectangular surfaces. The carton is glued into a sleeve along its long seam, and the code's panels are numbered 1 to 4 starting from that glue seam. The two leading blocks describe the closure systems — the bottom first (30), then the top (81); the following blocks record which panel each closure's flap is connected to.

Here the bottom end uses the tuck-in flap closure with scissor lock (30), and the top closure is recorded as 81.

Counting from the glue seam, the bottom flap hangs on panel 3.

How the closures behave

A tuck-in flap reinforced by interlocking dust flaps: the scissor lock resists the end being pushed open from inside, giving the closure noticeably more hold than a plain tuck without adding glue.

Typical uses

The scissor-locked variant suits contents that press against the closure — heavier or shifting products where a plain tuck could be pushed open in transit.

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.

What is ECMA A30.81.03.00?

ECMA A30.81.03.00 is a long-seam-glued folding carton in ECMA group A (base: tuck-in flap closure with scissor lock; top: closure system 81).

Which dimensions does the ECMA A30.81.03.00 dieline need?

5 parameters drive the blank: L (length), W (width), D (depth), B (hollow flap band), 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 ECMA A30.81.03.00 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.
