This paper considers the effect of precipitated calcium carbonate (PCC) filler clustering on sheet properties. We used three different PCC grades that have very different structures and we applied two different methods to prepare handsheets. On the basis of handsheet paper property measurements, cross-sectional SEM-images of handsheets and KCL-PAKKA simulations we conclude that fillers agglomerate to clusters that are strong enough to resist pressures during handsheet making and lead to increased bulk of the sheet.
