Quality Control and Documentation for Custom Packaging

Quality requirements should be defined before production. For custom paper box packaging, the approved structure, material, artwork, color standard, finishing process, sample direction, and packing method become the reference for production and inspection.

Inspection Points

  • Structure alignment, folding accuracy, edge quality, and glue strength.
  • Color consistency, logo position, print clarity, foil stamping, embossing, debossing, lamination, and spot UV quality.
  • Insert fit, box opening and closing feel, magnetic closure strength, drawer movement, and retail presentation.
  • Quantity check, carton protection, export packing marks, and shipment preparation.

Documentation Buyers May Request

Depending on the project and destination market, buyers may request material information, FSC paper options, artwork proof, sample photos, production photos, inspection photos, packing details, and shipping documents.

Best Practice for B2B Buyers

Confirm the final specification before mass production: box size, material, color, logo process, insert, quantity, tolerance, packing method, and delivery terms.
