Description
How Folding Cartons Are Made
A folding carton starts as a flat printed sheet. After printing and die-cutting, it arrives at your facility as a flat blank — creased, cut, and ready to fold. You assemble it in seconds, slip your product inside, and tuck the flaps.
The die-cut template (called a “dieline”) determines everything: the box shape, where it folds, how it locks, and how it looks. Getting the dieline right is the most important step.
Dieline Basics
A dieline shows:
- Cut lines (solid) — where the box is cut
- Crease lines (dashed) — where the box folds
- Tuck flaps — the locking tabs
- Glue flaps — where the box is glued (if needed)
We create the dieline based on your product dimensions. Always review the dieline before printing — this is the best time to catch structural issues.

Rule of thumb: If the product weighs over 200g, use 350gsm or heavier.
Printing Methods
Offset Lithography
The standard for folding cartons. Crisp detail, consistent color across thousands of boxes. Best for 500+ pieces.
Digital Printing
Short-run friendly. No plate setup cost, but slightly lower color accuracy. Good for prototypes and small batches.
Pantone Matching
For brand-critical colors, specify Pantone spot colors. This ensures your brand color is exact across all runs.

Special Effects (When Worth It)
- Foil Stamping — Always worth it for a logo. Instantly raises perceived value.
- Embossing — Great for tactile luxury brands. Pair with foil.
- Spot UV — Good for highlighting patterns or textures.
- Window Cutout — Worth it when seeing the product helps sell it.
Tip: Don’t use all four on one box. Pick one signature effect.
Structural Features to Consider
- Hang Hole (Euro Slot) — For retail peg display
- Window — Show the product inside
- Tear Strip — Easy opening for food/medical products
- Perforation — Easy-open or recloseable features
- Handle Hole — For larger boxes that need carrying
Common Design Mistakes
- No bleed — Artwork must extend 3mm beyond the cut line
- Wrong panel — Front panel graphics must match the right panel
- Ignoring glue flap — Don’t put important design on the glue flap
- Text too close to edges — Keep text 5mm away from cut lines
- Not proofing the dieline — Fold a mock-up before full production
