Paper Structure
The end use of the paper defines the basic fiber properties.
Sophisticated controls are necessary to produce an accurate paper profile,
which is measured in microns.
The fiber mix also requires certain additives to
obtain the expected paper characteristics. Mineral fillers, such as china clay,
talc and calcium carbonate, make the paper smoother and more receptive to ink.
They also improve opacity, brightness and printability. Mineral pigments,
together with dyes, give the desired shade. Finally, binders such as starch and
latex are added to provide strength and right ink absorption characteristics.
Goodrich Agrochem’s paper strength additives improve fiber to
fiber bonding which enhances the opacity and brightness of paper.
