Custom Shipping Box Generator
Cardboard shipping box die-lines with cut and score lines on separate layers, ready for LightBurn.
Box style
One cross-shaped sheet with taped corners and several creases on each wall. The flap folds over at whichever crease suits the product.
Inside size (mm)
The space for your product. Wall allowance for the board thickness is added for you.
Board
Corrugated is usually 1.5 mm (E-flute) to 4 mm (B/C-flute). Measure your own board.
Creases
Besides the base crease, the first wall crease is at your height and the rest follow at the score gap. Fold the flap over at whichever crease suits the product.
Creases at 63, 73, 83 mm from the base, plus the base crease on all four sides. The first is at your height; the flap beyond the last one folds over the top (front and back cover it, left and right are shorter).
Flap corners
Square corners are the default. Chamfered corners cut the tips off flaps and tabs, which can make tucks and tabs slide in more easily.
Output
Spacing and line width in the file.
The LightBurn file puts scores on C01 and cuts on C02. The speed and power in it are placeholders, so set both layers from your own test grid for your board. Make a test grid.
Pricing these boxes?
The flat sheet size above is what you buy per box. Put it into the material estimator to see how many fit on a board and what each one costs.
Cutting and folding tips
- Score lines should crease the board, not cut it. Set the score layer to Perforation mode with Cut 5 mm and Skip 5 mm and test on offcuts, adjusting power until it folds cleanly without breaking the liner.
- Run the flutes parallel to the main fold lines so the board bends along its channels.
- Check the fit with a paper or thin-card prototype before cutting the real board.
- Always test settings on scrap, and keep the extraction on. Cardboard can flare.
