Latest development of enzymatic technologies provides a new level of stickies control

摘要

Stickies contribute to a significant reduction in efficiency in the practice of papermaking using recycled fiber. The presence of adhesives, binders, tapes s and other stickies-creating materials in the incoming pulp leads to machine downtime, a reduction in converting efficiency, final product quality issues and increased waste. Enzymatic technologies have proven successful in providing stickies control in mills over the past decade; however, on their own they were not able to solve the problem completely for certain types of contaminants. Greater control of stickies at paper mills is now being achieved by combining new generation enzymatic formulations with specific additives to stabilize enzymatic resistant stickies. This approach keeps the stickies small, dispersed, and non-tacky to eliminate agglomeration downstream and keep them fixed into the outgoing sheet. The latest generation of enzymatic technologies has proven to lead to a superior level of stickies control than previous generations.
