Abstract

A multi-ply paper product is disclosed. The multi-ply paper product is provided with a first play and a second ply. The first ply is a lotioned fibrous structure having a wet burst of less than about 100 grams. The second ply is a non-lotioned fibrous structure having a wet burst of greater than about 100 grams.

Claims

1. A multi-ply paper product comprising:

(a) a first ply comprising a lotioned fibrous structure having a basis weight of less than about 18 g/m² and a wet burst value of less than about 80 grams;

(b) a second ply comprising a non-lotioned fibrous structure having a basis weight of greater than about 19 g/m² and a wet burst value of greater than about 125 grams; and

,

wherein said multi-ply paper product has an overall wet burst value, said overall wet burst value being greater than the arithmetic sum of said wet burst value of said first ply and said wet burst value of said second ply.

2. The product according to claim 1, wherein said first ply has a total dry tensile of less than about 500 grams per inch, and said second ply has a total dry tensile greater than about 500 grams per inch.

3. The product according to claim 1, wherein said first ply has a cross-machine direction stretch less than about 7%, and said second ply has a cross-machine direction stretch greater than about 7%.

4. The product according to claim 1, wherein said first ply has a void volume of less than about 120 mm³, and said second ply has a void volume of greater than about 120 mm³.

5. The product according to claim 1, wherein said first ply has a bulk density of greater than about 0.10 g/cm³, and said second ply has a bulk density of less than about 0.10 g/cm³.

6. The product according to claim 1, wherein said second ply has printing disposed thereupon.

7. The product according to claim 1, wherein said first ply is ply bonded to said second ply.

8. The product according to claim 1, wherein said overall wet burst value ranges from about 10.8% to about 16.2% greater than the arithmetic sum of said wet burst value of said first ply and said wet burst value of said second ply.

9. The product of claim 1, wherein said multi-ply paper product is folded.

10. A multi-ply paper product comprising:

(a) a first ply comprising a fibrous structure having a softening additive disposed thereon, a basis weight of less than about 18 g/m², and a wet burst value of less than about 80 grams;

(b) a second ply comprising a fibrous structure having no softening additive disposed thereupon, a basis weight of greater than about 19 g/m², and a wet burst value of greater than about 125 grams; and

,

wherein said multi-ply paper product has an overall wet burst value, said overall wet burst value being greater than the arithmetic sum of said wet burst value of said first ply and said wet burst value of said second ply.

11. The product of claim 10, wherein said first ply has a total dry tensile of less than about 500 grams per inch, and said second ply has a total dry tensile value greater than about 500 grams per inch.

12. The product of claim 10, wherein said first ply has a cross-machine direction stretch less than about 7%, and said second ply has a cross-machine direction stretch of greater than about 7%.

13. The product of claim 10, wherein said first ply has a void volume of less than about 120 mm³, and said second ply has a void volume of greater than about 120 mm³.

14. The product of claim 10, wherein said first ply has a bulk density of greater than about 0.10 g/cm³, and said second ply has a bulk density of less than about 0.10 g/cm³.

15. The product of claim 10, wherein said second ply has printing disposed thereupon.

16. The product of claim 10, wherein said first ply is ply bonded to said second ply.

17. The process of claim 10, wherein said multi-ply paper product is folded.

18. The product according to claim 10, wherein said overall wet burst value ranges from about 10.8% to about 16.2% greater than the arithmetic sum of said wet burst value of said first ply and said wet burst value of said second ply.

19. A multi-ply paper product comprising:

(a) a first ply comprising a fibrous structure having a softening additive, a basis weight of less than about 18 g/m², and a lotion disposed thereon, said first ply having a wet burst value of less than about 80 grams;

(b) a second ply comprising a fibrous structure having no softening additive and no lotion disposed thereupon, said second ply having a basis weight of greater than about 19 g/m² and a wet burst value of greater than about 125 grams; and

,

wherein said multi-ply paper product has an overall wet burst value, said overall wet burst value being greater than the arithmetic sum of said wet burst value of said first ply and said wet burst value of said second ply.

20. The product of claim 19, wherein said first ply has a basis weight of less than about 16.5 g/m² and said second ply has a basis weight of greater than about 19 g/m².

21. The product according to claim 19, wherein said overall wet burst value ranges from about 10.8% to about 16.2% greater than the arithmetic sum of said wet burst value of said first ply and said wet burst value of said second ply.
