## Abstract

The present invention provides multi-ply tissue products having distinctly different first and second outer surfaces or sides. The two-sidedness is generally provided by forming one of the surfaces from a tissue ply having a plurality of macrofolds and the other side from a substantially planar tissue ply. The first ply may be attached to the second ply at longitudinally spaced apart points that define a macrofold therebetween. The length of tissue between the points of attachment may form a wave-like structure having an amplitude and wavelength and having a transversely orientated void that extends from a first edge to a second edge of the tissue. The combination of these elements provides a tissue product that is both aesthetically pleasing and well suited to cleaning due to the large amount of surface area created by the macrofolds.

## Claims

### Claim 1

A tissue product having a machine direction (MD) and a cross-machine direction (CD), a first upper surface and an opposed bottom surface, the product comprising:
a first tissue ply having a basis weight from about 10 to about 45 grams per square meter (gsm) and sheet bulk greater than about 5 cubic centimeters per gram (cc/g) and a first MD length,
a second tissue ply having a basis weight from about 10 to about 45 grams per square meter (gsm) and sheet bulk greater than about 5 cubic centimeters per gram (cc/g) and a second MD Length,
a plurality of substantially CD orientated lines of perforation spaced apart from one another in the MD and defining a plurality of sheets therebetween, the sheets having a sheet length (L);
wherein the first MD Length is substantially equal to the sheet length (L) and the second MD Length is at least about 150 percent of the sheet length (L).

### Claim 2 (depends on 1)

The tissue product of claim 1 wherein the first ply is substantially planar, and the second ply comprises a plurality of substantially CD orientated macrofolds defined by points of attachment between the first and second plies, the points of attachment being spaced apart from one another in the MD.

### Claim 3 (depends on 2)

The tissue product of claim 2 wherein the points of attachment are substantially equally spaced apart from one another a distance from about 5.0 to about 16 mm in the MD.

### Claim 4 (depends on 2)

The tissue product of claim 2 wherein the points of attachment extend substantially continuously in the CD.

### Claim 5 (depends on 2)

The tissue product of claim 2 wherein each of the plurality of macrofolds are similarly sized and shaped.

### Claim 6 (depends on 2)

The tissue product of claim 2 further comprising a plurality of dot embossments disposed on the second ply between the spaced apart points of attachment.

### Claim 7 (depends on 1)

The tissue product of claim 1 wherein the second MD Length is from about 120 to about 600 percent of the sheet length (L).
