Laminated paper consists of TiO2 up to 40 % Ma-% and more. Savings in TiO2 resulting in decreasing costs in production while keeping the very high quality of this type of paper is important for all producers of laminated paper. A new high functional filler is used to find out the advantages when used in laminated paper.
Rapid Koethen, 40 % ash content
VP TRF_1, Suspension, 2, 4 and 8 % in exchange with TiO2
Melamin and acrylat resin
- The new high functional filler was easily brought into the paper making process
- The parameter of the base paper have been equal or better, for example: TiO2-Retention, Brightness, Tensile strength
- Also the quality of the paper after lamination was equal or even better, for example: Opacity, Brightness, Stability against Xenon light
- 8 Ma-% of the previously used TiO2 (100 Ma-%) have been replaced by the high functional filler while keeping the quality of the paper after lamination
