Straight tuck end carton: blank size formula and dieline
A glued tube with a tuck flap at each end, both hinged on the same face. The front stays clean top and bottom, which is why retail cartons often use it.
Blank size calculator
The formula
| Blank length | 2L + 2W + 4t + g |
|---|---|
| Blank height | no exact formula: use the calculator |
- L, W, H
- internal length, width and height
- t
- board caliper (0.45 mm for 350 gsm SBS)
- g
- glue flap width: 14 mm by default
Around the carton: 2L + 2W + 4t + g, the same as the reverse tuck.
The height of the blank has no exact formula: the tuck flap and dust flaps are capped to fit the carton. Use the calculator for it.
Example. 90 × 45 × 160 mm inside on SBS / GC1 board 350 gsm (t = 0.45, g = 14): blank 285.8 × 307.35 mm.
Per board
The same 90 × 45 × 160 mm inside on each board. Thicker board means a bigger blank for the same inside size.
| Board | t (mm) | g (mm) | Blank (mm) |
|---|---|---|---|
| SBS 350 gsm | 0.45 | 14 | 285.8 × 307.35 |
| FBB 400 gsm | 0.55 | 14 | 286.2 × 307.65 |
| Kraft 400 gsm | 0.5 | 14 | 286 × 307.5 |
| Greyboard 1.0 mm | 1 | 14 | 288 × 309 |

- Reverse tuck: the tuck flaps on opposite faces.
Questions
- Why does a straight tuck use more board?
- With both flaps on the same face, two blanks cannot be turned to nest into each other on the sheet, so there is more waste between them.
