Paper and paperboard
Reverté’s calcium carbonates, recommended for paper pulp, make it possible to achieve high retention during the sheet formation process, which allows maximum substitution of cellulose fibre. This brings about an increase in the whiteness and opacity of the paper, allowing a reduction in consumption of optical whitener.
Reverté’s calcium carbonates, recommended for coating and pre-coating of paper and paperboard make it possible to reduce the consumption of kaolin and achieve greater whiteness, while maintaining high levels of gloss and opacity.
