Abstract

A method for forming a package including a stack of absorbent tissue paper material and a packaging, the tissue paper material in the stack forming 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, and the packaging encircling the stack so as to maintain the stack in a compressed condition in the package, with a selected packing density D0 of the stack, and a selected packing height H0; the method including: forming the stack of absorbent tissue paper material; compressing each portion of the stack in a direction along the height to assume a temporary height H1 being c1×H0, where c1 is between 0.30 and 0.95; and applying the packaging to the stack.
