Three inspections on every order

Fourteen people work in quality control, and they report to the plant manager, not to sales. Each order passes three checks, and you receive the last report before the balance is due.

  • Print registration and coating coverage
  • Die-cut accuracy within 0.5 mm

Tests we run in our own lab

Edge crush and burst strengthCorrugated board, every new board grade and once per production batch
Drop testPacked shipping cartons, from the height that matches their weight
Rub resistancePrinted and laminated surfaces, to check that ink does not scuff in transit
Colour measurementSpectrophotometer readings against the signed sample, under a standard light booth
Closure cyclesMagnetic lids and drawer boxes opened and closed repeatedly
Handle pullPaper bag handles loaded to the weight the bag is rated for

Food-contact and chemical tests are done by an accredited outside laboratory, and the report is issued in your company name on request.

If something arrives wrong

Tell us within 30 days of delivery and send photos of the defect and the carton label. A quality engineer replies within two working days with the cause and a proposal.

Where the fault is ours, we remake the affected quantity at our cost or credit it against your next order. You choose which.

Check us before you order

You can audit the plant in person, send a third-party inspector, or walk the floor with us on a video call. We will show the presses, the lab and a live order on the line.
