Abstract
In general, the present disclosure is directed to creped tissue webs, and products produced therefrom. The creped webs and products are strong, soft, and have fine crepe structure, such as less than about 12, measured as % COV at a STFI wavelength of 16 to 32 mm, using the test method set forth herein. Fine crepe structure is achieved even at basis weights in excess of 16 gsm per ply.
Claims20
A creped tissue product comprising at least one creped tissue web having a basis weight greater than about 16 gsm, a fine crepe structure, measured as % COV at a STFI wavelength of 16 to 32 mm, of less than about 12 and a geometric mean tensile less than about 500 g/3″.
A multi-ply tissue product comprising two multi-layered creped tissue webs, the tissue webs having three superposed layers, an inner layer consisting essentially of softwood fibers and two outer layers consisting essentially of hardwood fibers, the inner layer being located between the two outer layers, wherein each web has a geometric mean tensile of less than about 500 g/3″, a basis weight of at least about 16 gsm and a fine crepe structure, measured as % COV at a STFI wavelength of 16 to 32 mm, of less than about 12.
A creped tissue web having a first side and a second side and a creping composition comprising a non-fibrous olefin polymer disposed on at least the first side, wherein the tissue web has a geometric mean tensile of less than about 500 g/3″, a basis weight of at least about 16 gsm and wherein a fine crepe structure, measured as % COV at a STFI wavelength of 16 to 32 mm, of less than about 12.
