Abstract

Official abstract text for this publication.

An all-purpose type tissue paper. A two-ply tissue paper that does not have moisturizer applied thereon, that has a basis weight per ply of 10.0-16.0 g/m2, a paper thickness per two-ply of 120-200 μm, a softness of not more than 1.0, a dry tensile strength (T) in the MD direction of 240-300 cN/25 mm, and an average dynamic friction coefficient of 1.40-1.65.

First claim

Opening claim text (preview).

The invention claimed is: 1. A two-ply tissue paper having no moisturizer coated thereon, comprising: a basis weight per one ply of from 10.0 to 16.0 g/m 2 ; a paper thickness per two plies of from 120 to 200 μm; a softness of 1.0 or less; a dry tensile strength (T) in MD of from 240 to 300 cN/25 mm; and an average dynamic friction coefficient of from 1.40 to 1.65, wherein the tissue paper is produced without a moisturizer coating, and wherein the tissue paper is produced by using a combination of a softener compound, a wet paper strengthening agent and a dry paper strengthening agent.
