Packaging Dieline Studio Pro
A browser-based packaging CAD tool. Generate production-ready structural dielines from real engineering rules — cut, crease, bleed, safe-area and glue geometry — with a live 2D layout, instant 3D box, an engineering score, sheet-yield optimizer and print-ready SVG / PDF / DXF / PNG export.
Reverse Tuck End
production-accurateStructural feasibility of the current spec.
Illustrative estimates at your quantity. For full costing use the cost, break-even & ROI tools.
SVG & PDF are scaled 1:1 in millimetres (PDF opens in Illustrator/Acrobat). DXF exports layered CUT / FOLD / BLEED / SAFE / GLUE lines for die-makers. To wrap real artwork on the 3D box, use the 3D Packaging Visualizer.
Need this die-cut & printed?
Send your dieline spec and we’ll quote tooling, printing and production. Your structure, dimensions and material attach automatically.
Dielines are generated from real structural geometry and are production-oriented, but every job differs by material, machine and converter. Always confirm the final dieline, fold allowances, knife offsets and tolerances with your printer or die-maker before tooling. Material, board-compensation and cost figures are estimates for planning. Auto-lock / crash-lock bottoms, seal-end, five-panel hanger, rigid and pouch structures are on the roadmap.
The free packaging dieline generator with live 3D
Most online tools give you a flat picture and a quote button. This packaging dieline generator is closer to packaging CAD software online: a real packaging structural design tool that builds production-ready box geometry, shows it in live 2D and 3D, scores its manufacturability and exports print-ready files. Whether you need a folding carton template maker, a corrugated box dieline generator or an online dieline creator for a mailer or tray, it generates the structure parametrically from your dimensions — not as scaled artwork.
What is a packaging dieline?
A dieline is the flat blueprint of a box. It defines every cut, every fold and the glue areas, so a printer and die-maker can reproduce the package exactly. Artwork is placed on top of this structure as a separate layer. A correct dieline is what separates a professional print-ready box template from a drawing that looks right but won’t fold — which is why this box layout generator derives panels, flaps and glue from real engineering rules and applies board-thickness compensation at every crease.
How to create production-ready box dielines
Using the custom box dieline generator above takes four steps:
- Pick a structure — reverse or straight tuck carton, RSC, HSC, FOL, mailer or tray.
- Enter internal length, width and height in mm, cm or inches.
- Set material and caliper, then bleed, safe area and glue-flap width.
- Review the live 2D dieline, 3D box, engineering score and sheet yield — then export.
Everything updates instantly, so you can tune dimensions for fit and material efficiency before you ever request tooling.
Understanding cut lines, fold lines, bleed and safe areas
Dielines use a colour standard that every printer recognises. This packaging die-cut template generator follows it exactly:
How to design custom folding cartons
Folding cartons — tuck-end boxes in particular — are the workhorses of retail packaging. A reverse tuck end (RTE) has its top and bottom tuck flaps on opposite panels (easy to assemble, common for cosmetics and supplements), while a straight tuck end (STE) places both tucks on the same panel for a cleaner front face. The generator lays out the four walls plus a glue flap, adds tuck and dust flaps automatically, and compensates panel sizes for board caliper so the folded box hits your internal dimensions. This is the heart of a true folding carton design software workflow, now free in the browser.
Corrugated box dieline standards
Corrugated structures follow their own conventions. A Regular Slotted Container (RSC) has flaps that are each half the box width, meeting in the centre — the standard shipping box. A Half Slotted Container (HSC) is open at one end (a tray or sleeve), and a Full Overlap (FOL) uses full-width flaps that overlap for extra strength and dust resistance. Choose your flute (E, B, C or BC) and the tool adjusts thickness, the 3D look and the cost basis accordingly, helping you build a sound corrugated box dieline or mailer box template before production.
Preparing artwork for printing
Once the structure is right, prepare the print file: extend backgrounds to the green bleed, keep text and logos inside the orange safe area, and keep critical elements off folds and the purple glue area. Use CMYK at 300 DPI and embed or outline fonts. To preview real artwork wrapped onto the box, open the dieline alongside our 3D Packaging Visualizer, which maps artwork to each panel and flags low-resolution or misaligned graphics.
Common packaging dieline mistakes
How to export dielines for offset and digital printing
The generator exports four print-ready packaging template formats. SVG and PDF are scaled 1:1 in millimetres and open cleanly in Illustrator and Acrobat for offset or digital print. DXF exports on separate CUT, FOLD, BLEED, SAFE and GLUE layers for die-makers and CAD/CAM. PNG gives a quick visual proof. Send the SVG or PDF to your printer with your artwork on a separate layer, and the DXF to whoever cuts the die. As a dieline creator with 3D preview and a built-in sheet optimizer, it bridges structural design, costing and production in one place.
