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.

First claim

The invention claimed is:

1. 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 dry crepe material,
the stack, when in said package, having a selected packing density D0 of 0.25 to 0.65 kg/dm 3 , 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 D0,
wherein said absorbent tissue paper material is a combination material comprising at least one ply of a dry crepe material and one ply of a structural tissue material.

2. A package according to claim 1 , wherein the selected packing density D0 is 0.25 to 0.60 kg/dm 3 .

3. A package according to claim 1 , said packing density D0 being >0.20 and ≤0.35 kg/dm 3 and said package displaying a piston imprinting load as described herein at 3 mm imprint level IM 3 being less than 130 N or said packing density D0 being >0.35 and ≤0.65 kg/dm 3 and said package displaying a piston imprinting load as described herein at 3 mm imprint level IM 3 being less than 500 N.

4. A package according to claim 1 , said packing density D0 being >0.20 and ≤0.35 kg/dm 3 and said package displaying a piston imprinting load as described herein at 6 mm imprint level IM 6 being less than 500 N, or said packing density D0 being >0.35 and ≤0.65 kg/dm 3 and said package displaying a piston imprinting load IM 6 as described herein at 6 mm imprint level being less than 8000 N.

5. A package according to claim 1 , said packing density D0 being >0.20 and ≤0.35 kg/dm 3 and said package displaying a piston imprinting load as described herein at 3 mm imprint level IM 3 and a piston imprinting load at 10 mm imprint level IM 10 , wherein IM 10 /IM 3 is greater than 3; or
said packing density D0 being >0.35 and ≤0.65 kg/dm 3 and said package displaying a piston imprinting load as described herein at 3 mm imprint level IM 3 and a piston imprinting load at 10 mm imprint level IM 10 , wherein IM 10 /IM 3 is greater than 4.5.

6. A package according to claim 1 , said packing density D0 being >0.20 and ≤0.35 kg/dm 3 and said package displaying a piston imprinting load as described herein at 3 mm imprint level IM 3 and a piston imprinting load at 6 mm imprint level IM 6 , wherein IM 6 /IM 3 is greater than 1.5; or
said packing density D0 being >0.35 and ≤0.65 kg/dm 3 and said package displaying a piston imprinting load as described herein at 3 mm imprint level IM 3 and a piston imprinting load at 6 mm imprint level IM 6 , wherein IM 6 /IM 3 is greater than 2.

7. A package according to claim 1 , wherein said stack is a stack of folded absorbent tissue paper material.

8. A package according to claim 7 , wherein said folded absorbent tissue paper material is a continuous web material.

9. A package according to claim 8 , wherein the stack comprises at least one continuous web material being Z-folded.

10. A package in accordance with claim 1 , wherein said packaging is a wraparound strip.

11. A package in accordance with claim 1 , wherein said packaging is of a material having a tensile strength, S in a direction along the height of the stack, of less than 10 kN/m 2 .

12. A package in accordance with claim 1 , wherein said packaging is of a material having a tensile strength, S in a direction along the height of the stack, of at least 1.5 kN/m 2 .

13. A package according to claim 1 , wherein said packaging is made of a paper, non-woven or plastic material.

14. A package according to claim 1 , wherein said packaging is closed to encircle said stack by means of a seal.

15. A package according to claim 14 , wherein said seal is an adhesive seal.

16. A package according to claim 14 , wherein said seal is an ultrasonic seal or a heatseal.

17. A package according to claim 1 , wherein the selected packing density D0 is 0.25 to 0.55 kg/dm 3 .

18. A package according to claim 1 , wherein the selected packing density D0 is 0.30 to 0.55 kg/dm 3 .
