Commercial value requires both favorable process economics and
good FFU. By constantly experimenting with all the possible options
of an existing process, it is often possible to optimize both cost and
performance.
Suppose that you need to create a piece of paper to handwrite a note.
Because of the exibility of human handwriting and our innate ability to
discern shapes on paper, the FFU range of this paper product is very wide.
The task can be accomplished with almost any variety of plant ber. Every
ber process, from a handheld screen to a huge paper mill, can do the job.
