Paper Pulp
Pulp is the raw material for paper products, prepared by separating out cellulose fibers from wood or fiber crops. It is used to form a web structure which is bleached to create paper.

Because paper is formed from this web of pulp, accurate surface monitoring at the pulp machine stage ensures early detection and classification of any imperfections that might affect later processing.

Pulp is the basic building block of paper and is key to the production of all paper products, from paper sheets to car and cardboard products.
