AquaKote™ Coated Unbleached Paperboard

AquaKote™ coated unbleached paperboard (also known as coated unbleached kraft or CUK) is a high-strength sheet when both wet and dry and is ideal for beverage multipacks and frozen food applications.

Available in a wide range of grades, AquaKote is designed to provide package integrity, line efficiency, and superior performance even in environments with high humidity. It offers high resistance to tear, puncture, and corner crush.

Made from a blend of renewable wood-based fiber from sustainably managed forests and recycled fiber.
