• SolarScreen Wave: a full range of standard UV LED screen inks
• SolarFlex FDW and Slalom: standard and food-compliant opaque whites for labels and sleeves, now optimised for UV LED
• SolarVerse: a system of pigmented bases and technology varnishes designed for special colour mixing of UV flexo inks in standard, compliant and UV LED profiles. The system offers significant advantages in simplification and sustainability.

Advancing circular packaging

Sustainability and compliance with rapidly advancing extended producer responsibility (EPR) legislation (e.g., Europe’s Packaging and Packaging Waste Regulation (PPWR)) remain a top priority for Sun Chemical. At Labelexpo, Sun Chemical brought a wide selection of solutions for labels and packaging that facilitate recycling.

Key developments include:

• Retention grade recyclable solution: SolarWave Integra UV LED ink combined with EV-LU029 coating.
• Washable/deinking solution: SolarFlex CRCL—compatible with recycling processes based on ink retention or deinking (US market).
• Electron Beam (EB) solutions: EB-curable inks and coatings tailored for mono-material and monolayer packaging structures.

In addition, Sun Chemical introduced a new migration-compliant screen ink portfolio for labels, as well as a migration-compliant varnish, tactile varnish and SolarScreen Wave: a full range of standard UV LED screen inks.
