Recycled fiber is a major source of raw material for the modern recycled paper mill. Stickies are a major obstacle to manufacturing high-quality paper. They challenge the process of using recycled or secondary fiber sources. And they tend to deposit on machine surfaces, fabrics, wires, felts, and rolls, which leads to runnability problems such as paper breaks at the press. If not controlled, stickies can also lead to paper quality issues such as holes, sheet defects, and high dirt counts.
Enzymes are the sustainable alternative to chemicals. They efficiently convert the stickies into more manageable components, thereby improving machine performance. More importantly, enzymes have the ability to improve the recycled paper’s quality in terms of spots, holes, and breakage as well as preventing damage from stickies.
