Inks and varnishes

Challenges

Continued growth in markets such as UV labels and UV inks for flexible packaging

                                                      

Constantly more regulatory requirements to support the food packaging industry

                                                     

Technical developments driven towards better curing response and lower viscosities                                                                       

Seeking for adhesion on wide variety of substrates

Tendency for low filmweight materials

Digital printing moving towards industrial applications

Impact of REACh and related labelling changes (EuPIA, …)

Brand Owners guidelines (Nestlé, …)

Food Packaging directives (Swiss Ordinance, …)

Analogue: combination of high reactivity and low shrinkage materials for flexo printing

Digital: inkjet printheads with smaller and smaller drop size for better print quality

High performance UV cure resins for printing inks

Sartomer has developed a full range of specialty acrylate resins to offer solutions for the complete set of UV printing technologies:

 

 

  • Inkjet
  • Offset
  • Flexo
  • Screen
  • OPV

 

A pioneer in the development of specialty acrylates for UV LED curing systems

We believe UV LED technology to be the future of UV printing, for it is a lower energy-consuming option than traditional Hg-doped lamps. UV-LED lamps offer a narrow but intense spectral emission, which requires highly functional reactive material, available in our product range.

LED lamp designed for UV LED curing acrylate systems

A strong expertise and anticipation of evolving regulations and directives:

  • A full and personalized support to address REACH market transition
  • Compliance with most influential brand owner’s requirements (BPA free, organotin free, PETIA free solutions)
  • Low migration LM range of products for food packaging applications, being
    guaranteed to be compliant with the Swiss list and Nestlé guidance notes, with no risk
    of contamination and a very low potential for migration.
