In addition to coated papers, titanium dioxide is also used in the production of specialty papers, such as those used for labels, packaging, and security documents. In these applications, titanium dioxide is added to the paper pulp to increase the opacity and brightness of the paper. This helps to create a more professional and appealing appearance for the final product, as well as providing enhanced security features through the use of fluorescent or UV-reactive titanium dioxide particles
