Special production technologies for special papers

Specialty Paper Machines

The range of use of specialty papers

    It takes a very special kind of expertise to manufacture specialty papers for items like bank notes or thermal receipts. This is why for each specialty paper our production technologies are tailored to the specific application.

    Paper machines not only produce volume grades such as newsprint, they also provide paper for tea bags and gasoline filters, bottle labels, wallpaper and décor coverings for furniture as well as backing paper for vinyl wallpapers.

    Fascinating and versatile

    A quick look in your wallet will suffice to give you an idea of the versatility of specialty papers: The fuel receipt is printed on thermal paper, the banknotes consist of special banknote and security paper, and without the photographic-based paper your family photo would look only half as good. Cigarette papers, decor papers and labels are also categorized as specialty papers. Although specialty papers only account for five percent of worldwide paper consumption, they achieve much greater added value compared with mass-produced papers.

    Expert know-how for specialty paper production

    The challenges involved in the manufacture of specialty papers are diverse. Because they are generally only produced in small production lots of up to a ton, the requirements for the paper machines are stringent. Voith is heavily involved in the production of specialty papers and for decades has been developing new technologies and products to enable its more efficient and higher quality manufacture. We supply products and technologies for all grades of specialty papers. The high quality level and consistency of quality of coated and uncoated specialty papers is always a key consideration. This is why our production technologies for each specialty paper are tailored to every specific case.

            Dryer section

            Dryer Section

            In the dryer section, the remaining water is evaporated by the supply of heat energy. In this case the paper web is led over dryers that are heated from the inside by means of steam. At the end of the drying process, the paper has a residual moisture of approximately 2% to 9 % depending on the grade.
