CPI conducts at industrial scale, the surface functionalization of films and fabrics by continuous (roll-to-roll) plasma treatment at atmospheric pressure. CPI has developed specific functionalization and deposition methods based on innovative chemistry. Applications include bonding, digital printing, flexible packaging, lamination, etc.

A wide range of efficient surface functionalizations

• Stable high surface energy up to 72 mN/m with exceptional wettability and adhesion (anti fog possible). See case study here.
  
• Hydrophilic / hydrophobic balance and biocompatibility adjustment.
  
• Stable low surface energy (lower than 20 mN/m) with adjustable release properties. See case study here.
  
• Functionalization and grafting by covalent bonds.
• Optimized surface chemistry: amines / amides-imides equilibrium.
• Nanocoatings (silica, silicone...).

Over a wide range of flexible substrates

• Polymer films, fabrics, woven and nonwoven (PP, BOPP, PE, PET, PA, PVC, FEP, PTFE, ETFE, ECTFE, PVDF, PVF, PEEK etc.).
• Cellulose, paper, ceramics, glass, metal, metallized films.

Providing exceptional benefits

• Adhesion and printing without primers.
• Printing with all types of inks (water based, solvent based, UV / EB crosslinkable, digital).
• Improving adherence to laminating, metallization and varnishing.
