Materials

    Brown testliner

    FSC certified paper, brown testliner is a cost-effective paper. It reduces the carbon footprint and cost of your mailer.
  2. Bk

    Brown kraft liner

    FSC certified, unbleached and uncoated liner paper made from virgin pulp. Brown kraft liner is a sustainable material that still provides high print performance.
  3. Wk

    White kraft liner

    FSC certified, bleached liner paper made from virgin pulp. White kraft liner is a good option for printing bold colours without choosing a coated paper.
  4. B

    B-flute

    B-flute (2.5-3.5mm) is commonly used across boxes of any size. It has good crush resistance and its thickness offers extra cushioning.
  5. Wb

    Water-based inks

    Made with water as their primary base, these inks are designed for flexographic printing. More sustainable than solvent-based inks.
  6. Sp

    Single peel & seal

    One strip of adhesive covered with a fibre-based backing paper. A single peel & seal makes fulfilment fast and helps make your packaging tamper-proof. Adding a peel & seal has minimal impact on your carbon footprint.

Quality control

Every lot from our suppliers undergoes a quality inspection process before it’s shipped. Any lot that fails quality inspection is returned to the manufacturer or reproduced.

For orders manufactured internationally (outside the UK), we follow the Acceptable Quality Limit (AQL) method defined by ISO 2859 - 1.

For orders manufactured domestically (inside the UK), our suppliers perform the quality inspection process which we then verify through spot checks throughout the year.
