The flat dieline

The carton with arch window laid flat at its starting size. Solid lines are cut; dashed lines are folded. In the studio this drawing updates as you change the size, and downloads with bleed and dimensions.

Parts of a auto-lock bottom carton

An auto-lock carton, also called a crash-lock bottom, has a tuck top and a bottom that the printer pre-glues. When you push the flat carton open, the bottom flaps fall into place and lock by themselves. That makes it fast to pack and strong underneath, which is why it is used for heavier retail products: glass bottles, jars, supplements and boxed gifts. The extra gluing step at the printer makes it a little more involved to produce than a plain tuck box.

Body panels: Front, back and two sides, joined by the glue flap, as on any folding carton.
Crash-lock bottom flaps: Four flaps that overlap and are glued at angled zones while the carton is flat, so the bottom forms as the box opens.
Top tuck flap: Hinges from the back panel and tucks in to close the top.
Top dust flaps: Fold in under the top tuck and keep the top square.
Glue zones: Areas on the bottom flaps that must stay free of varnish so the pre-gluing holds.

How to size it

Measure the product at its widest points, including any cap or pump.
Add 1 to 2 mm on length and width and 2 to 3 mm on height. Heavier products may need a snugger fit so they do not shift.
Enter Inside sizes in the studio; the outside size is shown under the fields.
Very small or very flat cartons are hard to crash-lock. If the bottom is tiny, ask your printer whether a tuck or snap-lock bottom is more practical.

Materials and finishes

Duplex board, 300 to 400 gsm: Standard for heavier retail cartons. Thicker board gives the bottom more strength.
FBB or SBS board, 300 to 400 gsm: Premium products that need a clean white finish and crisp folds.
E-flute laminated board: Heavy or fragile items. Printed board laminated onto thin corrugated adds a lot of strength.

Finishes

Varnish or lamination: Protects the print. The bottom glue zones must be left uncoated.
Window with clear film: Available in the studio as rectangle, oval or arch on the front panel.

Mistakes to avoid

Sending the concept dieline straight to production. Crash-lock flaps need the printer's own glue zones and angles; this dieline draws them as plain overlapping flaps.
Varnish or lamination over the bottom glue areas, which stops the pre-glue from holding.
Choosing auto-lock for a product light enough for a tuck bottom. You pay for the extra gluing without needing the strength.
Putting key text on the bottom flaps. They overlap, so parts of the artwork are hidden once the base locks.

How to make it in the studio

Open it. Press Customise this carton with arch window. It opens in the 3D studio at 90 x 60 x 140 mm.
Set the size. In the Size panel, choose whether you are entering the Inside or Outside size, then type your measurements. The other one is shown underneath.
Add your design. In the Design panel, upload your logo or artwork: it goes on the front first. Pick other faces to add colours, text or images to each.
Check it in 3D. Turn the pack around, and use the Flat to Closed slider to watch it fold. Switch to the Dieline view to see the artwork on the dieline.
Download. The Download panel gives you the PDF dieline to send your printer first, then mockup images for your store or social posts.
Get it made. If you want a quote, send the design to packitmama from the Download panel, and we will reply personally.

Questions

Auto-lock or snap-lock?

Both are strong. Auto-lock is pre-glued and pops open, so it is faster for packing many units. Snap-lock needs no extra gluing but is folded by hand, which is slower.

Can I see how the bottom closes?

Yes. The Flat to Closed slider in the studio folds the carton, and the 3D view turns it around.
