5. The tissue product according to claim 1 , wherein the un-embossed inner ply is adjacent to the first outer ply or second outer ply.
6. The tissue product according to claim 1 , wherein at least three inner plies are provided and
a first inner ply not adjacent to the first outer ply or second outer ply is provided with a micro-embossing pattern; and
a second inner ply between the first inner ply and either the first outer ply or second outer ply is un-embossed.
7. The tissue product according to claim 6 , wherein the micro-embossing pattern of the first inner ply extends essentially all over the surface of the first inner ply.
8. The tissue product according to claim 1 , the tissue product either comprising a stack of individual sheets or a roll with transversely extending weakening lines to subdivide the web into individual sheets.
9. The tissue product according to claim 8 , wherein the embossing is in register with the dimensions of the individual sheets of the tissue product.
10. The tissue product according to claim 1 , wherein the application of glue is restricted to an overall surface fraction of less than 12% of the tissue product.
11. The tissue product according to claim 1 , wherein the décor embossing region of the first outer ply further comprises second embossed décor protrusions with a smaller height than the height of the first embossed décor protrusions.
12. A tissue product with at least four plies made of tissue paper base sheet or nonwoven, comprising:
a first outer ply and a second outer ply and at least two inner plies between the first outer ply and the second outer ply,
wherein
only one of the inner plies is un-embossed;
at least one of the outer plies comprises a décor embossing pattern;
at least two adjacent inner plies comprise the un-embossed inner ply and one micro-embossed inner ply;
the outer plies comprise a micro-embossing pattern, wherein either the density of the micro-embossed protrusions of the micro-embossed inner ply is different to the density of embossed protrusions of the micro-embossing pattern of the outer ply which is adjacent to the micro-embossed inner ply or the micro-embossed protrusions of the micro-embossed inner ply and the embossed protrusions of the adjacent outer ply are not in register with one another;
