Abstract

The invention relates to a process for using papermaking techniques to make a sheet material. This material copmrises, in addition to the fibres, an organic binder, a non-binding mineral filler and a flocculant, as well as various conventional additives, this process being characterized by the fact that the mineral filler and the binder are flocculated beforehand before being incorporated into the fibre suspension. The material thus prepared has enhanced mineral filler retention and physical properties and can be used as printing and writing medium, covering medium, packaging medium or for obtaining complexes for industrial or foodstuffs use.
