32 PAUL CO I LOTOS CORE INNOVATION INSPIRED BY NATURE In many parts of Asia the lotos is consid ered a symbol of purity an idea that has its origins in the self purifying impression made by the plant The lotos flower which always looks as if it has been freshly washed aroused the curiosity of botanist Wilhelm Barthlott who finally uncovered the mystery under a microscope in the 1970s The lotos leaves are covered with wax covered papillae that cause dirt and water to simply bead up and roll off Many products with surface sealing properties resulting from this discov ery are in use throughout the world today LOTOS QUALITY A MILE STONE IN SURFACE DEVELOPMENT As is so often the case customer needs are the driving force for innovations Nitto Belgium NV provided the crucial impetus for development of the Lotos core in 2019 when the company approached us with the intention of finding an alternative to a core with cellophane outer ply used for winding a special film The challenge was to develop a completely new surface coating with strong release properties and there was a narrow time frame for finding a solution The work began and the research and development department at Paul Co s main site in Wild flecken developed a water based emulsion with which they treated the cores using a special process Extensive internal tests followed and the results filled everyone with enthusiasm The innovation called the Lotos core has all the required properties The core was also convincing in the application tests at Nitto It enables perfect adhesion of the film during winding and completely residue free unwinding The changeover to the Lotos core was a success FOCUS ON SUSTAINABILITY We were excited by the idea of developing a core that has an excellent release effect while also exhibiting water repellent properties However it had to be 100 recyclable and meet the requirements of adhesive films and all of this had to be accomplished with out the use of nanotechnology
