  • SolarFlex® LED is based on SolarVerse™, Sun Chemical’s new range of highly pigmented, low viscosity, multipurpose UV flexo concentrates
  • Due to its patented M-Cure® photoinitiators, SolarFlex LED is rapid curing, ensuring full cure at high press speeds, and is fully compliant with regulations for food, pharmaceutical, tobacco and cosmetics packaging
  • SolarFlex LED delivers superb printability and ink transfer and low foaming characteristics for the most reliable press performance
  • It also has robust adhesion characteristics, allowing printers to use it on a wide range of plastic substrates, and provides high holdout on even the most absorbent substrates for increased print quality
  • The process inks are complemented by a surface print LED curing flexo opaque white with opacity and whiteness enabling high quality transparent labels and flexible packaging to be produced fully with LED curing

Modern Technology Built into SolarFlex LED


Mark Walkling, Product Manager, ECP Packaging & Narrow Web Labels, Europe, Sun Chemical Ltd, comments: “In the past, converting from standard UV flexo technology to food packaging compliant inks has meant compromising on print quality and adhesion.

The modern technology built into SolarFlex LED is based on the same SolarVerse™ concentrates at the same levels as used in other UV Flexo inks from Sun Chemical meaning no change in color standards, no change in aniloxes and no change in color matched formulations."

"The conversion to LED brings even more challenges and SolarFlex LED delivers the same high strength inks, the same great rheology and press performance and the same widespread adhesion characteristics. This really is a step forward for printers wishing to convert to LED and expand their horizons into the food packaging market.
