Flint Group Narrow Web further expands its low migration inks portfolio with custom designed metallic silver and metallic pastes. As with all of Flint Group’s low migration products, these specialty inks have been tested and proven to have the best low migration properties.
Migration measurements show that with Low Migration UV Flexo Silver, migration levels below 10 ppb may be achieved when correctly applied on suitable packaging structures. This was verified based on the standard migration test method using the food simulants 95% ethanol as set out in Commission Directive 97/48/EC.
This silver exhibits very good metallic performance, cure speed, and adhesion to a wide range of both paper and synthetic substrates. Low Migration UV Flexo Silver is fully compliant with the Swiss Ordinance SR 817.023.21 listing and the Nestlé Guidance Note on Packaging Inks (version 2.1 Jan 10th 2013).
Flint Group is offering three metallic pastes suitable for use in low migration ink systems, Rich Gold, Pale Gold, and Silver. These are first generation metallic pastes suitable for narrow web low migration applications and are for use as 2-component ink systems.
Flint Group Narrow Web has designed a 2-component concept which allows printers to purchase the necessary components allowing them to mix gold and silver shades locally, in both Lithocure ANCORA (UV offset) and the Flexocure ANCORA (UV flexo) systems. These components have been designed to meet today’s market requirements and have proven to pass the most stringent migration tests applied by the industry.
These custom designed low migration metallic inks and pastes are available now in Europe; these inks will be available March of 2014 in North America.
Flint Group Narrow Web offers a full range of UV low migration inks, including UV flexo; UV offset, UV metallic; UV flexo cold foiling adhesive; UV flexo laminating adhesive; UV flexo Low COF Shrink White; and several other UV flexo coatings.
