Abstract

A cleaning substrate (1) comprising an absorbent layer (2); a surface layer (3) comprising a macro-apertured laminate (31) of a thermoplastic formed film (32) and a nonwoven layer (33); wherein said thermoplastic formed film (32) is in direct contact with said absorbent layer (2), and said macro-apertured laminate (31) has a thickness (35) of from 0.5 mm to 1.5 mm.

Claims

1. A cleaning substrate comprising

a. an absorbent layer;

b. a surface layer comprising a macro-apertured laminate of a thermoplastic formed film and a nonwoven layer;

wherein said thermoplastic formed film is in direct contact with said absorbent layer, and said macro-apertured laminate has a thickness of from about 0.5 mm to about 1.5 mm.

2. A cleaning substrate according to claim 1, wherein said macro-apertured laminate has a thickness of from about 0.7 mm to about 1.2 mm.

3. A cleaning substrate according to claim 1, wherein said macro-apertured laminate has a thickness of from about 0.8 mm to about 1 mm.

4. A cleaning substrate according to claim 1, wherein said macro-apertured laminate comprises from about 5 to about 20 holes per square centimeter.

5. A cleaning substrate according to claim 1, wherein said macro-apertured laminate comprises from about 7 to about 15 holes per square centimeter.
