Flint Group Narrow Web introduces Evolution Series for enhanced recycling
Flint Group Narrow Web Introduces ‘Evolution Series’ of Coating Products for enhanced Recycling
New UV-flexo coatings recognized by APR to comply with critical guidance for PET packaging; to be highlighted at Label Congress 2021, booth #51
Rogers, Minnesota, USA, 21 September 2021: 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.
Evolution Deinking Primer is applied by the conventional UV-flexo process and works with Flint Group’s EkoCure® XS flexo inks that are specially designed for shrink sleeves.
The second product, the Evolution Caustic Resistant OPV, is a UV-flexo overprint varnish to facilitate recycling PET bottles utilizing pressure-sensitive labels. The varnish minimizes contamination of the wash water and bottle flake in the caustic bath by keeping the ink secured to the label substrate. When immersed in the float-sink bath, the label is released from the bottle and floats to the surface where it is separated from the bottle recycling stream.
Neither the Deinking Primer nor the Caustic Resistant OPV has any impact on ink color, image quality or code readability. This means that converters can have a smooth transition to the new coatings.
The coatings will be the highlight of Flint Group Narrow Web’s stand presentation at the Label Congress (booth #51, Donald E. Stephens Convention Center, Rosemont, IL, 29-30 September 2021). They are the first products in Flint Group’s Evolution Series, designed to bring positive impacts on sustainability in the label and packaging value chains.
John Pogatschnik, North America marketing manager, Flint Group Narrow Web, comments: “The Deinking Primer and Caustic Resistant OPV are simple to use and offer optimal performance at all stages of the label or sleeve lifecycle, while meeting the stringent requirements of the APR critical guidance. Switching to these new products is disruption-free, has no adverse effect on functionality, and works with our standard inks.
“Both products are ‘plug and play’ solutions that enable better recycling without impacting the quality or application performance. A converter doesn’t need to qualify a new ink series and rematch several colors: simply splice into a recognized substrate, turn on the primer or OPV, and more sustainable labels or sleeves are rolling up on the winder.”
