Mineral Fillers for Folding Carton and Containerboard

Omya offers a portfolio of standard and specifically-designed Calcium Carbonate grades to meet growing demand in containerboard, folding carton and coreboard markets.

Improved Opacity
Omya mineral fillers feature excellent scattering properties which allow minimizing the white top fiber ply without compromising opacity. This opens opportunities for light-weighting or bulk increase.
Enhanced Brightness
High Calcium Carbonate filler load enables a lift in brightness level of white top fiber plies. A broad filler portfolio offers the customer a wide range of possibilities to achieve specific brightness requirements.
Increased Efficiency
The dewatering effect of Omya fillers on the paper web can be used to reduce drying energy or increase line speed. Beside fiber replacement, this allows producers to either generate cost savings or to maximize output. Excellent filler performance and our reliable product supply provide quality consistency in your board manufacturing process.

Omya Mineral Fillers Help Realize Efficiency Gains and Optimize Costs

Machine output can be a limiting factor in growing markets like containerboard and folding carton. Adding Omya Calcium Carbonate fillers to the production process provides a significant increase in output rates. The natural properties of Calcium Carbonate improve drainage which leads to higher line speeds, reduced energy cost, and lower dependence on virgin and recycled fibers.
