Multilayer kraft back board
Klafold is a high-quality, coated unbleached kraft paperboard that uses less ber for a given caliper, yet still delivers exceptional weight advantage. Its exceptionally smooth surface makes Klafold an obvious choice for brands with dual objectives, both environmental and shelf impact. Clay coating provides a consistent, smooth surface with outstanding ink holdout resulting in excellent printability for graphic consistency. The unbleached, long ber base layer supplies excellent strength, making it versatile enough to take on virtually any design feature or application. It is also suitable for a wide range of food applications.
