Liquid Cellusol dyes for cardboard and testliner paper

We offer a unique range of dyes for packaging cardboard, the most diversified on the market. We can produce the exact colour you want and optimise the dyeing cost while adapting to your process specifications:

• Ready-to-use solution: mix of dyes formulated to order by our teams, to meet your specifications in terms of shade, colour fastness and use. This solution is the easiest to use.
• Trichromatic solution: selection of basic dyes which are dosed on site to precisely create all the variations of kraft nuances you want. This process enables you to adjust the shade during production depending on the quality of the recycled paper.

From our Saint Marcel platform in the Eure (France), we distribute our CELLUSOL Browns in containers or road tankers across the whole continent, with unrivalled responsiveness. Of course, our range of CELLUSOL dyes complies with all current regulations and guidelines, notably BfR XXXVI.

CELLUSOL liquid direct dyes and DIRECT powders

We are chemists and we think in colour. This dual expertise has enabled us to develop a range of dyes and guarantee their quality, from the sourcing of the raw materials through to delivery.

We thereby assure the quality of our dye syntheses, by using the best production techniques available, which guarantees you traceability and reliability.

Our discharges to water are processed in our own treatment plant and meet all the current standards in force in France. We thereby ensure that the impact of our dyes on the environment is as low as possible.

Our direct dyes are available from stock under the brands CELLUSOL (liquid in water) and DIRECT (powder). They are REACH compliant and are used in the manufacture of paper for sanitary and domestic use (tissue), office and printing paper and speciality papers.
