ABSORBENT TISSUE PAPER PRODUCT, METHOD AND APPARATUS FOR PRODUCING THE SAME
The present disclosure relates to an absorbent tissue paper product comprising one ply (10) being an essentially continuous ply (10) of fibrous structure having a first side (1) and a second side (2), said first side (1) having a surface roughness arithmetical mean height (Sa1), and said second side (2) having a surface roughness arithmetical mean height (Sa2). Said ply has a micro-embossed structure and a difference between the surface roughness arithmetical mean heights of the first side (1) and the second side (2) is 7μm or less (│Sa1-Sa2│≤ 7μm), and said ply (10) having a bulk of at least 7.5 cm3/g. The disclosure also relates to a method and an apparatus for producing such an absorbent tissue paper product.
