Abstract:Increasing filler content in paper and board is a important measure of saving fiber resource and decreasing production cost. There is a trend of increasing filler content in paper and board is, and it has been attracting more and more attention from the papermakers and end-users. In this paper, the role and significance of filler in paper and board were described, and the main technologies of improving filler content including lumen loading, filler modification, filler preflocculation, fiber modification, fine-filler composites were summarized.
