Abstract

The present invention provides for a tissue product comprising one or more tissue plies and having a total tensile value of less than about 1300 grams per inch, a Bulk₃₀₀ of greater than about 13.5 cm³/g, and a caliper stability of greater than about 50%. The present invention also provides for a tissue product comprising at least three plies. The tissue product has a total tensile value of less than about 1300 grams per inch, a Bulk₃₀₀ greater than about 11 cm³/g, and a caliper stability greater than 50%. The present invention further provides for a tissue product comprising as least two plies. The tissue product has a total tensile value of less than about 1300 grams per inch, a Bulk₃₀₀ of greater than about 7.0 cm³/g, and a caliper stability of greater than about 83%.

Claims
