Results showed that filler type affected the paper properties and sizing agent significantly, and PCC containing handsheets also had less negatively affected by fillers, and its optical properties have positively affected by mineral fillers. It noteworthy that sizing agent causes intensified undesirable impact of various fillers on paper.
