Wausau Paper Introduces New OptiServ(TM) Brand Dispensing System

MOSINEE, Wis., Sep 26, 2005 (BUSINESS WIRE) — Wausau Paper (NYSE:WPP) today announced the introduction of the new OptiServ(TM) brand hands-free roll towel dispensing system in its Bay West(R) line of “away-from-home” products. The patented OptiServ system features a quiet, touch-free dispensing mechanism that cuts a pre-measured 11-inch towel with each pull, lowering costs for customers by reducing product waste and maintenance time.

The new OptiServ hands-free dispenser, available in five translucent colors, features a contemporary design as well as a side-hinged door that provides ease when servicing and loading roll towels in the dispenser. The OptiServ dispenser complies with the Americans with Disabilities Act (ADA) standards for Accessible Design and, with no levers or buttons to push, supports the food safety principles of Hazard Analysis Critical Control Point (HACCP) because users touch only the paper when dispensing a towel.

“The OptiServ dispenser features an improved design and functionality and accommodates all Bay West controlled-use roll towels including our premium DublSoft(R) and 100% recycled EcoSoft(TM) Green Seal(R) products,” said Thomas J. Howatt, president and CEO. “With the addition of OptiServ, customers can now choose from a wider range of Bay West Dispensers to meet their business needs and help control costs. At the same time, placement of these innovative dispensers allows us to accelerate growth in our higher-margin, value-added product category.”
