Metered Size Press Coating Formulation Design for Fiber Reduction

A major driving force in paper technology development is the reduction in cost of paper production. A primary material cost in the paper production process is wood fiber, the cost of which is increasing rapidly. Reducing fiber usage is difficult, as paper properties are tightly coupled to the amount of fiber. Advances in coating formulation design have begun to show how coatings may be designed for fiber replacement without sacrificing paper properties. Both pigment and binder influence coating mechanical properties.
