The paper is focused on obtaining a new nanostructured composite by innovative technologies based on: fibrillar cellulose/titanium dioxide/surfactants (bolaform- dodecandioyl-diglycine and surfactant classic-collagen hydrolysate)/ethanol/water, for improved surface properties. Innovation consists in technologies for obtaining new nanostructured composites, solubilisation/compatibilisation of their component substances for the conditioning of supports processed with the film created by evaporation of the emulsion nanocomposites. Fibrillar cellulose/titanium dioxide nanocomposites have been stabilized with bolaform surfactants in a 1:1 ratio of ethanol/water solvents in order to increase the uniformity of titanium dioxide shell nanocomposites. Nanostructured “cauliflower”-like composites developed as a result of biopolymer-surfactant interactions for fibrillar cellulose/titanium dioxide/bolaform couple in ethanol/water system are reported by SEM microscopy. The analysis by FTIR-ATR spectroscopy of bolaform, fibrillar cellulose and dynamic light scattering of 2 types of nanocomposites emulsions (with bolaform and classic surfactant emulsions) were reported. The new nanocomposites could provide the hybrid film with increased mechanical resistance to water and heat. Supports processing with the composite film improve wet/dry friction resistance, water resistance and tensile strength. Environmentally-friendly supports with smart multifunctional features are obtained for various applications.

The Ji’an PM No. 3 is the first linerboard machine in China to use multilayer curtain coating technology. Since successful startup at the end of 2011, further development has been carried out to optimize running conditions, coating formulations, and the base paper to provide a product with satisfactory quality and lower cost to manufacture. The key challenges include designing the base board structure for the desired mechanical strength, designing the surface properties for subsequent coating operations, optimizing the high-speed running of the curtain coater to enhance production efficiency, minimizing the amount of titanium dioxide in the coating color, and balancing the coated board properties to make them suitable for both offset and flexographic printing. The pilot and mill scale results show that curtain coating has a major positive impact on brightness, while smoothness is improved mainly by the blade coating and calendering conditions. Optimization of base board properties and the blade + curtain + blade concept has resulted in the successful use of 100% recycled fiber to produce base board. The optical, mechanical, and printability properties of the final coated board meet market requirements for both offset and flexographic printing. Machine runnability is excellent at the current speed of 1000 m/min, and titanium dioxide has been eliminated in the coating formulations without affecting the coating coverage. A significant improvement in the total cost of coated white liner production has been achieved, compared to the conventional concept of using virgin fiber in the top ply. Future development will focus on combining low cost with further quality improvements to make linerboard suitable for a wider range of end-use applications, including frozen-food packaging and folding boxboard.
