WayhomartMedium volume, shelf-ready: sizing a dish rack colour box
A colour box costs volume. Cut the dieline from measured samples, replace the foam with paper-card locating, and approve a white sample before anything is printed.
Challenge
The retailer requires a colour box, but the box plus insert enlarges the carton and reduces units per container; and a dieline cut to nominal drawing dimensions may not close on production parts given wire tolerance and springback.
What we did
Dieline designed from the measured maximum of a sample with assembly clearance; paper-card locating replaces a foam or blister insert to control height; a white sample approves fit and stacking before the printed sample; barcode and label languages are fixed in the first revision.
Result
- Shelf-ready colour box with controlled insert volume
- Dieline based on measured parts, avoiding fit failures in production
- White sample first, so dieline problems surface before printing
What this file records
A configuration file, not a client story. Client identities and commercial figures are not published; no number is given where none was measured.
Three decisions that decide whether the box pays
| Decision | Approach | Effect |
|---|---|---|
| Dieline basis | Measured maximum of a sample, not the nominal drawing | Decides whether production parts fit |
| Insert format | Paper-card locating instead of foam or blister | Drives box height and loading |
| Approval order | White sample, then printed sample, then production | Decides where rework cost lands |
Cutting to nominal drawing dimensions is the most common cause of box rework: the drawing is nominal, the parts carry wire tolerance and springback. A few millimetres is enough to jam production.
Why the insert is worth redesigning
Box volume is not set by the product; it is set by product plus insert. A full foam or blister tray protects best, but it also raises the box — and height is the dimension container loading is most sensitive to.
Paper-card locating achieves most of the protection at the cost of a fold design that must be finished before the dieline is cut. Do it afterwards and it is rework.
The white sample saves the printing
A white sample is an unprinted box used to confirm two things: the product goes in and the carton survives stacking. Neither is about print, and both are where problems appear.
Printing first and fitting later usually means scrapping boxes or adding stickers. Print is the most expensive part of the box and the worst place to test dimensions.
Barcode and labels in the first revision
- Barcode supplied by the brand, position and quiet zone per the retailer; the shipping carton needs its own label.
- Label languages per market, consistent with the actual material and coating — never copied from a competitor.
- Warnings, where applicable, confirmed before print rather than stickered afterwards.
Details: three pitfalls of private-label boxes.
Loading has to be recalculated
Once the box is in, CBM per unit changes and so does the container. The method is in colour box or bulk; if two SKUs ship together, see a two-SKU mixed container.
