Production and processing of woodfree grades Chemical pulp dominating paper grades are usually produced in a neutral or alkaline papermaking process, giving good strength properties to the web. Neutral papermaking conditions allow the use of CaCO3 as a pigment and produce good archival properties in the paper. High amounts of fillers and hardwood pulp give
