Abstract

Current papermaking methods have not provided a paper in which the number of pinholes in the dome region of the finished paper web is substantially reduced. The present invention provides a paper web having two regions and comprising: an essentially continuous, essentially macroscopically monoplanar network region, and a dome region comprising a plurality of discrete domes, essentially all of said domes being dispersed throughout, encompassed by, and isolated one from another by said network region, at least about 40% of the X-Y area of each of said domes being not less than about 45 mils in each of its dimensions measured in the X-Y plane at the level of said network region, the density of said network region being greater than the density of said dome region. The resulting paper web is comprised of essentially a macroscopically monoplanar network region and a dome region in which the number of pinholes in the dome region of the finished paper web is substantially reduced.
