Coating, treatment, colouration
Colouring of substrates by coating
What is coating and treatment of flexible substrates?
Coating consists of coating the surface of a substrate with a solution called a coating, in order to give the treated substrate special technical properties and modify its appearance. Coating is used for industrial or graphic applications.
Coating Développement specialises in coating flexible substrates such as :
- Paper, card and cardboard from 45g to 450g
- Films from 35 µ to 400 µ (polypropylene, polyester, HDPE, etc.)
- Canvas (non-woven, polyester, PVC, etc.)
- Tyvek® soft and strong structures
Coating Développement has 3 coating lines
Coating Développement has a strong production capacity with 3 coating lines working simultaneously :
- 1 coater width 1600 mm
- 1 coater width 1475 mm
- 1 coater width 1300 mm
- Our coaters have the particularity of permitting us to put 4 layers in one pass : 2 layers recto + 2 layers verso.
Possibilities of coating are 1 g / m² to 100 g / m² in 1 pass, so a layer thickness of 1 µ to 120 µ in 1 pass.
Our machines can use rolls of 1,20 m of diameter, capacity of 1 tonne, with mandrels of 70 to 150mm.
Our techniques are adaptable to medium constraints:
- Coating air blade
- Coating Meyer bars
- Soft calender online

Coating and treatments provided by Coating Développement in France
Coating Développement develops formulae adapted to each use, each constraint and each client, according to strict confidentiality and environmental rules.
Our experience gives us the know-how in several domains and in very contrasting activity sectors.
Coating Développement treats substrates to give them technical properties such as :
- Alimentary
- Slip-resistent
- Antistatic
- Anti-tearing
- Barrier to grease, water, hydrophobic, water vapour, gases, oxygen, WVTR, UV, impermeable...
- Colouration, tinting, fluorescence
- Compostable
- Erasable
- Fire resistant, with anti-fire norm M1 / B1
- Glue (glue activated with water)
- Heat sealability
- Inkjet printable (water-based, latex, solvent), Laser, UV
- Phonic
- Mat, satin, bright
- PVDC waterproof
- Recyclable
- Security
- Siliconing
- Waterproofing
- Water-repellent
….
Some examples with which we can process :
- Tyvek® 1082D norm B1, printable
- Tyvek® 1073D norm B1, printable
- Soft Tyvek® flame retardant
- Paper 130g, 190g M1 for inkjet print (white, color, fluorescent)
- Coated paper for HP Indigo
- AquaPaper® : wallpaper non-woven pre-pasted on the back M1 for printing
- PVC M1 for printing
- Calque M1 for printing
- IgniCoat : Paper 190 g M1 for solvent printing
Heat-sealable and compostable cardboard coating
An example of our expertise:
Our Research & Development and Coating departments, in close collaboration with our suppliers and customers, have developed a coating that makes it possible to manufacture disposable packaging and tableware that is plastic-free, recyclable and even home compostable.
Treatment of cardboard & paper to give them properties such as :
- food-safe
- heat-sealable without plastic film
- recyclable in the paper industry
- and even compostable.
Quality control
The consistent quality of our products is controlled at every stage of their manufacture.
Coating Développement has set up its coating quality control laboratory as close as possible to its production lines.
