Ashland Purekote 23589 food-safe coating for packaging

Ashland has developed Purekote 23589, a coating that can be used safely in food packaging applications. The water-based coating delivers a matte appearance and velvety feel to paper and plastic bags, pouches, lidding films, foil bags and sachets.

Suitable for use with any food, including organic and natural products, the coating does not have temperature limitations. It is print receptive and can be used with film, foil and other substrates. It can be applied via a gravure or flexographic process with an enclosed-chamber doctor blade.

The coating can be pattern-applied to create packaging with both matte sections and clear windows that allow consumers to see the product inside. Its flexibility in application makes the coating suitable for use on pressure-sensitive labels, boxes and non-food applications.

Certified FDA compliant, the coating is a polyurethane dispersion in liquid form. As a topcoat, it delivers 60° gloss in the 0.5 to 4 range.
