World’s widest release paper production line successfully started up
Voith and Wuzhou Special Paper have successfully commissioned the new PM 21 specialty paper machine in Hanchuan, Hubei Province. It is the world’s widest machine for the production of release paper. The machine, supplied entirely by Voith, demonstrates the technology group’s leading role in the field of high-quality specialty papers. With a working width of 8.100 meters at the reel, the PM 21 produces around 300,000 tons of specialty paper per year with basis weights ranging from 35 to 120 g/m² – primarily lightweight glassine base paper.
Release paper is often used in everyday life to protect sticky surfaces, e.g., in separation applications. The base paper must meet specific requirements in terms of tear resistance, tensile strength, transparency, dense sheet structure, and low surface absorbency. It is characterized by a non-stick surface, which is achieved by coating it with silicone.
