Die-Cut Mailer Box dieline — real and manufacturable
This is a live die-cut mailer box dieline drawn by the same structural engine that produces our factory print files — not a stock template. Every cut line, fold line and glue zone below is the real construction (FEFCO 0427), built to the standard stock sizes this style is actually tooled and run at.

Pick a stock size — every panel, flap and glue zone redraws for it. Previews are watermarked; theproduction SVG/PDF with bleed exports from the studio on a paid plan.

The construction
Corrugated die-cut mailer (FEFCO 0427: floor root, side walls with wings, back wall carrying the lid and front tuck). The engine draws it panel by panel — so when you change the dimensions, the geometry recalculates the way a structural designer would redraw it, not the way an image stretches.
How to get a manufacturable die-cut mailer box dieline
1. Bring it or brief Sam
Upload a design from ChatGPT, Midjourney or your own designer — or brief Sam, our in-house AI packaging designer, from scratch.
2. Sam creates options
You get up to 4 real concepts, already mapped onto your true production dieline. Not mockups — the real structure.
3. Choose your favorite
Pick the direction you love. Every fold, panel, bleed and safe zone is already correct.
4. Fine-tune it
Final edits open up. Adjust anything with Sam until it feels unmistakably yours.
5. Place your exact assets
Drop in your real barcodes, QR codes, nutrition and legal copy — placed by you, pixel-perfect, untouched by AI.
6. Approve it on screen & order
The live preview is your proof — what you see is the production file. Approve it by ordering, and it goes straight to our factory, print-ready, and ships to your door.
Straight answers
Is this die-cut mailer box dieline print-ready?
Yes — it's generated by the same structural engine that builds our factory print files: real cut lines, fold lines, glue zones and dimension callouts. The preview above is watermarked; the production SVG/PDF with bleed exports from the studio on a paid plan.
What sizes does it come in?
This one runs in standard stock sizes rather than made-to-order dimensions, because corrugated is cut from fixed board and flute widths where an odd size wastes most of the sheet. Pick the nearest stock size in the studio and the dieline redraws for it. If you need a true custom size, a folding carton or pouch will do the same job at any dimensions.
What exactly is the construction?
Corrugated die-cut mailer (FEFCO 0427: floor root, side walls with wings, back wall carrying the lid and front tuck). At the sample size on this page the flat blank runs 557 × 554 mm (21.93" × 21.82") with 21 panels and 4 die-cut features.
Can you manufacture it too?
That's the point. Design on this dieline with AI in the studio, approve it on screen, and the same company manufactures and ships it.
