Abstract
A package including a stack of absorbent tissue paper material and a packaging, wherein, in the stack, the absorbent tissue paper material forms panels having a length, and a width perpendicular to the length, the panels being piled on top of each other to form a height extending between a first end surface and a second end surface of the stack; the absorbent tissue paper material including at least a structured tissue material, the stack, when in the package, having a selected packing density D0 of 0.20 to 0.65 kg/dm3, and exerting a force along the height of the stack towards the packaging, the packaging encircling the stack so as to maintain the stack in a compressed condition with the selected packing density D0.

A package comprising a stack of absorbent tissue paper material and a packaging, wherein, in said stack, the absorbent tissue paper material forms panels having a length, and a width perpendicular to said length, said panels being piled on top of each other to form a height extending between a first end surface and a second end surface of the stack;
- the absorbent tissue paper material comprising at least a structured tissue material, wherein the absorbent tissue paper material has a density of 0.08 and 0.20 g/cm3,
- the stack, when in said package, having a selected packing density of 0.20 to 0.65 kg/dm3, and exerting a force along the height of said stack towards the packaging, the packaging encircling said stack so as to maintain said stack in a compressed condition with said selected packing density,
- wherein,
- said packing density being >0.20 and ≤0.35 kg/dm3 and said package having a piston imprinting load at 3 mm imprint level (IM3) and a piston imprinting load at 10 mm imprint level (IM10), wherein IM10/IM3 is greater than 3;
- or
- said packing density being >0.35 and ≤0.65 kg/dm3 and said package having a piston imprinting load at IM3 and a piston imprinting load at IM10, wherein IM10/IM3 is greater than 4.
A package comprising a stack of absorbent tissue paper material and a packaging, wherein, in said stack, the absorbent tissue paper material forms panels having a length, and a width perpendicular to said length, said panels being piled on top of each other to form a height extending between a first end surface and a second end surface of the stack;
- the absorbent tissue paper material comprising at least a structured tissue material, wherein the absorbent tissue paper material has a density of 0.08 and 0.20 g/cm3,
- the stack, when in said package, having a selected packing density of 0.25 to 0.65 kg/dm3, and exerting a force along the height of said stack towards the packaging, the packaging encircling said stack so as to maintain said stack in a compressed condition with said selected packing density.
