Abstract
Lightweight multi-ply tissue products, such as facial tissue and bath tissue, are produced by printing flexible polymeric binder material, such as certain latex binders, onto one or more inner surfaces of the multi-ply tissue product. The resulting products have low stiffness and high strength.
Claims19
A multi-ply tissue product comprising two outer plies, each of the two outer plies having an inwardly-facing surface and an outwardly-facing surface, wherein the inwardly-facing surface of each outer ply has a print/creped application of a flexible polymeric binder material.
A method of making a multi-ply tissue product comprising:
- (a) providing a throughdried basesheet;
- (b) printing a flexible polymeric binder material onto one surface of the basesheet;
- (c) adhering the resulting printed surface of the basesheet to a creping cylinder and creping the basesheet, whereby the resulting basesheet has a print/creped surface and a non-print/creped surface;
- and
- (d) converting the resulting basesheet into a multi-ply tissue product having two outer plies such that the print/creped surface of each outer ply is facing inwardly.
