Arcweb TT 220 Laser-Imprintable Coating
A coating that forms a legible dark mark when struck by a laser marking unit on the filling line, so date and batch data can be applied without a ribbon or other consumable. The image forms in the coating itself, and mark contrast is set during qualification on the customer's marking unit.

1. Product description
A coating that develops a legible dark mark when struck by a laser marking unit on the filling line, so that date and batch data can be applied without a ribbon or a consumable. It is matched to the marking process by wavelength and by energy density, and the mark contrast is set during qualification on the customer’s marking unit. It differs from TT 110 in that the image is formed in the coating itself rather than transferred onto it.
2. Features
- Dark mark formed in the coating by the line's laser, with no ribbon or consumable
- Matched to the marking process by wavelength and energy density
- Mark contrast set on the customer's marking unit during qualification
- Usable on sleeve film where the line marks after sleeving
3. Recommended uses
Date, batch and traceability coding applied by laser on the filling line, on coated paper, PP and PET label face stock and on sleeve film marked after sleeving.
Substrates. Coated paper, PP and PET face stock, and sleeve film where the line marks after sleeving
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Water-based binder carrying a laser-reactive marking additive | Formulation |
| Appearance | Liquid drying to a film on which the laser forms a dark mark | Visual |
| Carrier | Water | Formulation |
| Non-volatile content | 30 to 45 per cent by weight | ISO 3251 |
| Supply viscosity at 23 °C | 20 to 40 s, 4 mm flow cup | ISO 2431, 4 mm orifice |
| pH | 8.0 to 9.0 | ASTM E70 |
| Mark legibility | Contrast, and for codes the barcode grade, set during qualification on the customer's laser at the agreed wavelength and energy density | ISO/IEC 15416 for linear symbols; ISO/IEC 15415 for 2D symbols such as Data Matrix; otherwise customer or supplier protocol |
| Rub and scuff resistance | 200 to 400 cycles under a 2 lb, 0.91 kg, weight without loss of mark legibility or print removal | ASTM D5264 |
| Block resistance, rewound reel and stacked sheet | No picking or transfer after 16 h at 40 °C under 10 kPa | ISO 4622 |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Flexo or gravure in line, narrow-web |
| Surface preparation | Corona treat filmic face stock and sleeve film in line at the time of coating, and check wetting tension before the run |
| Dilution | Supplied ready for use; adjust only with small additions of water where needed |
| Applied dry coat weight | 1.5 to 2.5 g/m² |
| Drying | Hot air; on sleeve film, keep the web cool enough that the film does not begin to shrink on press |
| Marking | Downstream laser marking on the filling line, after sleeving where sleeve film is used; wavelength and energy density are set during qualification so that the mark develops fully without perforating, blistering or distorting the sleeve film or face stock |
| Qualification | Mark contrast and legibility are confirmed on the customer's marking unit before release |
Process. Flexo or gravure, narrow-web; downstream laser marking, qualified by wavelength and energy density
6. Storage and handling
Store in the original closed container at 5 to 30 °C, protected from frost and direct sunlight, 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.
