Abstract
The incorporation of fillers in paper has been common practice for many years. Though the term ‘filler’ is somewhat uncomplimentary, this group of predominately inorganic materials has become a very essential component of many grades of paper. The original purpose of adding filler to the paper matrix was to lower furnish costs with the amount of filler limited only by strength considerations. Today the principal need for fillers is to impart specific quality improvements to the sheet. Depending on the performance characteristics of the fillers and the amount added to the paper, these products can improve the optical, physical, and aesthetic properties of the finished sheet. Today the practice of utilizing fillers is based on choosing materials which will provide both cost and quality improvements. The conversion to alkaline papermaking in North America has emphasized this approach, where fillers designed to add value to the paper are routinely used. This trend has been confirmed by the rapid growth in the tonnage of valued-added speciality fillers purchased by paper mills.
