Flint Group Narrow Web introduces Evolution Series for enhanced recycling
Flint Group Narrow Web introduces two UV-flexo coating products to improve the recyclability for shrink sleeves and pressure sensitive labels. These coatings are currently available in North America and will soon be available in Europe and other regions. Using different chemistries, the Evolution Deinking Primer, for shrink sleeves, and the Evolution Caustic Resistant Over Print Varnish (OPV), for self-adhesive labels, are designed to increase the yield of material in the recycling process. Both coatings have been recognized by the Association of Plastic Recyclers to comply with the critical guidance for PET packaging. The Evolution Deinking Primer is a coating used on shrink sleeve materials that makes the ink release in the caustic bath of the recycling process. When used with crystallizable polyester shrink sleeve material (CPET), the primer keeps the ink anchored to the substrate through the usable life of the sleeve, but releases it in the caustic bath. The ink is removed from the sleeve material without contaminating the valuable bottle flake. The materials are then rinsed and pelletized into recycled polyester (rPET) for reuse.
