Product-specific defect classes include ring misalignment or non-closure, PP weld separation, print registration and Pantone deviation against the approved sample, lamination bubbles or delamination, board warp and burrs on die-cut edges.

Private-label terms built into the way we work

Most of what leaves this factory carries someone else's name. That arrangement only works if it is complete, so these are standing terms rather than concessions.

  • No factory marks or logos on your product or cartons beyond what the law requires.
  • Unbranded or buyer-branded packaging, with your barcodes and labelling applied here.
  • An NDA signed before artwork changes hands.
  • Your artwork is never reused, never shown in our samples and never published.
  • We do not name our customers or describe who we produce for.
  • Tooling made for your product is stored separately and used for no one else.
  • Neutral documentation is available where you drop-ship to your own customers.
