Abstract
A multi-ply tissue paper product includes at least four plies made of tissue paper base-sheet or non-woven. Two inner plies are positioned between a first outer ply on one side and a second outer ply on another side. The two inner plies are flat plies. The first and second outer plies include a micro-embossing pattern. Only one of the outer plies further includes a décor embossing pattern. The multi-ply tissue paper product is configured to provide improved thickness and strength parameters with less use of paper fiber material.
