InactiveCN101360863AImprove surface smoothnessImprove smoothnessNon-fibrous pulp additionFlexible coversSurface finishingFlexural rigidity
A paperboard containing microplatelet cellulose particles has improved surface smoothness, aesthetic properties, bending stiffness and strength performance. When microplatelet cellulose particles are used for surface treatment of the paperboard, the microplatelets fill voids between fibers on the board surface. As a result, treated board has enhanced strength and surface properties such as smoothness, opacity, coating hold-out, and printability without compromising bending stiffness. Furthermore, the present disclosure relates to a process for improving board strength, surface smoothness and / or bending stiffness without the needs for densification, while maintaining other desired performances.
