Die-Cut Mailer Box dieline — real, manufacturable, any size
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), parametric to any dimensions you type in the studio.

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 the proof & order
See the real proof, approve it, and order. 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.
Can I get it in a custom size?
Yes. The construction is parametric — type your exact length × width × depth in the studio and every panel, flap and glue zone recalculates. Nothing is stretched.
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 the proof, and the same company manufactures and ships it.
