Sun Chemical’s NC-free solvent-based inks and RecyClass-certified lamination adhesives provide a full system for recyclable flexible packaging in flexographic and gravure printing.
Sun Chemical has received RecyClass certification for its nitrocellulose-free (NC-free) solvent-based solutions for flexible packaging. The approval covers a full system combining NC-alternative inks and certified lamination adhesives, supporting flexographic and gravure printing applications.
The SunUno SoliCycle range, a polyurethane (PU)-based ink system, is designed for surface and lamination printing. These inks meet regulatory requirements while maintaining performance for flexible packaging. They are available as ready-made inks or modular systems using concentrates and technology varnishes, allowing converters to customize formulations for production needs.
PU is recommended as an NC substitute due to its stability, print performance, and recyclability compatibility. PU supply is supported through Sun Chemical’s parent company DIC and Sapici, acquired in 2022.
Sun Chemical also offers RecyClass-certified lamination adhesives under the SunLam range for polyethylene (PE) flexible packaging recycling streams, including colored PE. The ULM adhesives cover medium to high performance depending on the structure. Together, NC-free inks and certified adhesives provide converters with a single-source solution for recyclable flexible packaging.
Romain Cleret, Sun Chemical EMEA Flexible Packaging Product Director, stated: “We are proud to be among the first in Europe to achieve RecyClass certification for versatile solvent-based NC alternative inks and to provide certified solutions for flexible packaging printers. This system enables our customers to proceed with greater confidence as the industry transitions toward more recyclable packaging systems.”
