ECMA A60.81.01.00
Hollow Dust Flap Top Auto-Lock Bottom Carton. A long-seam glued carton with an automatic two-point glued closing — the crash-lock base that springs shut as the sleeve is squared at the base and hollow dust flaps at the top.

STRUCTURE NOTES
About this construction.
Reading the code A60.81.01.00
A60.81.01.00 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 (60), then the top (81); the following blocks record which panel each closure's flap is connected to.
Here the bottom end uses the automatic (pre-glued) closure system (60), and the top closure is recorded as 81.
Counting from the glue seam, the bottom flap hangs on panel 1.
How the closures behave
The base is glued during carton manufacture and folds flat; when the packer squares the sleeve, the base springs into place already closed — the crash-lock principle that makes this the fastest base to erect on a filling line.
Typical uses
Pre-glued automatic bases are the high-throughput answer: the carton erects in one movement, which pays off on fast filling lines and for products packed in volume.
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 Retail Product Box — Hollow Dust Flap Top, Auto-Lock Base?
ECMA A60.81.01.00 is a long-seam-glued folding carton in ECMA group A (base: automatic (pre-glued) closure system; top: closure system 81).
Which dimensions does the Retail Product Box — Hollow Dust Flap Top, Auto-Lock Base dieline need?
5 parameters drive the blank: L (length), W (width), D (depth), B, 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 Retail Product Box — Hollow Dust Flap Top, Auto-Lock Base 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.
