Ashland Receives U.S. Patent for Innovative Topcoat for Flexible Food Packaging
Ashland has received US patent 9,539,795 for its PureKote™ 23589 dispersion and PureKote™ 21412A cross-linking agent coating system. The technology tandem creates a coating for flexible packaging that is water and scuff resistant. It also improves consumer appeal with soft-touch feel and matte finish. The coating system may be used safely in food packaging applications regulated by the U.S. Food and Drug Administration, including paper and plastic bags, pouches, lidding films, foil bags and sachets.
PureKote 23589 is a water-based dispersion in liquid form. PureKote 21412A is a 100-percent solids cross-linking agent. As a top coat, the system delivers 60° gloss in the 0.5 to 4 range, depending on the substrate used. PureKote coating is particularly well suited for packaging used on foods and pet foods labeled natural or organic. It can also be used on pressure-sensitive labels, boxes and other non-food applications.
