Arcfibre CP 310 Preprint Flexo Gloss Coating
A water-based flexo gloss coating for corrugated liner preprint, applied on a wide-web press before the liner is combined on the corrugator. It dries fast at web speed and stays flexible and free of blocking and pick-off against the hot plates and holddown belt at the double backer.

1. Product description
A water-based flexo coating for liner preprint, applied on a wide-web press before the liner is combined on the corrugator. It is formulated to dry fast at web speed and to stay flexible and free of blocking and pick-off at the double backer, where the printed liner is pressed onto the glued flute tips and carried across the hot plates with the coated face in contact with them. It is the standard gloss and holdout grade of the subfamily, used where the finished case needs a printed, coated liner of a quality that postprint cannot reach.
2. Features
- Fast drying at wide-web press speed
- Remains flexible through the double backer and hot plate section
- Resists blocking and pick-off against hot plates and holddown belt
- Standard gloss and holdout grade of the preprint subfamily
3. Recommended uses
Gloss and protective coating over preprinted liner for corrugated cases where the printed face needs a quality that postprint cannot reach. Used on coated and uncoated kraft, white top, test and recycled liner.
Substrates. Coated and uncoated kraft liner, white top liner, test liner, recycled liner for corrugating
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Water-based acrylic dispersion flexo coating | Formulation |
| Appearance | Milky liquid drying to a clear gloss film | Visual assessment, supplier protocol |
| Carrier | Water | By formulation |
| Non-volatile content | 30 to 40 per cent by weight | ISO 3251 |
| Flow time, 4 mm flow cup at 20 degrees C | 30 to 40 seconds | ISO 2431 |
| pH at 20 degrees C | 8.0 to 9.0 | ISO 976 |
| Gloss at 60 degrees | 40 to 70 gloss units on coated white top liner, lower on uncoated white top, kraft, test and recycled liner | ISO 2813 |
| Dry rub resistance, Sutherland, 2 lb weight | 100 to 250 cycles without visible transfer, liner and ink dependent | ASTM D5264 |
| Behaviour at the double backer | No blocking, pick-off or loss of gloss at the customer hot plate temperature and belt pressure, confirmed on corrugator trial | Customer or supplier protocol |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Wide-web central impression or stack flexo press, anilox applied |
| Surface preparation | Coat the printed face only and keep the coating off the glue side, as starch adhesive bonds to bare fibre |
| Dilution | Supplied ready for use; adjust press viscosity with 0 to 5 per cent water by weight |
| Applied dry coat weight | 1.5 to 3 g per square metre, by grammage difference to ISO 536 |
| Drying | Hot air and IR on the press, fully dry before rewind; line speed is set by web tension, anilox volume, dryer capacity and liner absorbency |
| Next step | Reel combined on the corrugator at the double backer; confirm hot plate temperature, belt pressure and combining speed on trial |
| Handling and safety | Refer to the Safety Data Sheet, issued by Arctic on request. |
Process. Wide-web central impression or stack flexo press, anilox applied, hot air and IR drying, the reel then combined on a corrugator
6. Storage and handling
Store in the original closed container at 5 to 30 degrees C, protected from frost and direct heat, and stir gently before use. Shelf life is stated on the label and Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
