Claim 0:
1. A multi-layer substrate including a top surface layer comprising tissue paper, a bottom surface layer comprising tissue paper, and a thermoplastic material that comprises polyethylene or has a tan delta value of from 0.2 to 0.4 within the temperature range of 100° F. to 350° F. wherein the multi-layer substrate is formed by the following process:
(a) providing the top surface layer comprising tissue paper, the tissue paper including fibers;
(b) providing the bottom surface layer comprising tissue paper, the tissue paper including fibers;
(c) providing the thermoplastic material;
(d) sandwiching the thermoplastic material between the top and bottom surface layers, and heating the thermoplastic material to a temperature at which the thermoplastic material softens, so as to bond the thermoplastic material to groups of fibers in the tissue paper top and bottom surface layers that are in contact with the thermoplastic material as it softens, such that no chemical adhesives are used to adhere the top and bottom surface layers to the thermoplastic material;
(e) wherein after heat softening, the thermoplastic material includes open pores through the thermoplastic material, providing a fluid pathway therethrough such that any liquid loaded into the top surface layer is able to pass through the fluid pathway, into the bottom surface layer; and
(f) wherein a cleaning composition is loaded onto the multi-layer substrate wherein the fluid pathway through the thermoplastic material allows the cleaning composition to travel between the top surface layer and the bottom surface layer.
