How to Design a Custom Corrugated Box for Shipping and Branding

Start from the product, not the catalogue

Internal dimensions should be taken from the product plus the minimum clearance the protection requires. Every extra centimetre is void fill you buy and dimensional weight you pay a carrier to move.

Pick the flute for the filled weight

Flute grade is a structural choice driven by the weight and how the box will be stacked, not by price alone. Tell the factory the filled weight and how many will be stacked on a pallet, and let the specification follow.

Decide how the box will be closed and opened

Self-locking mailers need no tape, which removes a step from every order packed, and they open by hand, which stops customers cutting into the contents with a blade. Regular slotted boxes cost less per unit but need tape and a knife.

Plan the inside print with the outside

The inner face is what the customer sees in the first two seconds after opening. Inside printing costs nothing structurally, and it is the cheapest brand moment in the whole pack.

Choose the board colour deliberately

Kraft is cheapest and reads as natural. White carries full-colour artwork best and shows handling marks fastest. Black dyed board hides scuffs and stands out in a delivery van, at a higher material cost.

Prove it with a sample before you commit

Ask for a sample made to the final specification and test it with your real product, your real packing station and, if you can, your real carrier.

Talk it through with the factory

If you are specifying a box now, send the product dimensions, the filled weight and the quantity. We will come back with a structure recommendation rather than a catalogue.
