OptiLux Bulk and Opacity Technology
OptiLux® bulk and opacity technology structures the sheet so that it has more air to fiber interface. This unique chemistry increases bulk and opacity, allowing for a reduction in basis weight, increasing bulk and stiffness by 4-8% and improving opacity by 1-3 points.
