  • Patent number: 11753225
    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.
    Type: Grant

  • Patent number: 11542048
    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.

  • Patent number: 11033156
    Abstract: A package including a stack of absorbent tissue paper material and a packaging, wherein, in the stack, the tissue 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 dry crepe material, the stack, when in the package, having a selected packing density D0 of 0.25 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.

  • Patent number: 10875705
    Abstract: A transport package including a compressible packaging and a packing configuration, the packing configuration including at least three individual stacks of absorbent tissue paper material, and the packaging maintaining said individual stacks in the packing configuration, the transport package forming a rectangular parallelepiped delimited by six outer surfaces, defining three transport package extensions extending along three perpendicular dimensions in space defining a length, a width, and a height of the transport package. A relative deformation of the transport package is defined for each of the three dimensions, being the relative shortening of the transport package extension along a selected dimension when the entire transport package is compressed with a deformation pressure of 15 kPa between two outer surfaces and along the selected dimension, wherein, for said transport package, the relative deformation along at least two out of the three dimensions is less than 10%.
