Abstract

The specification discloses a method for making a paper material having a reduced tendency to cut human skin. The Method includes providing a papermaking furnish containing cellulosic fibers and from about 0.5 to about 5.0 wt% by weight dry basis expandable microspheres, forming a paperboard web from the papermaking furnish, drying the web, and calendaring the web to a caliper of from about 18.0 mils and a density ranging from about 7.0 to about 12.0 1b/3000ft2/mil. Papers formed according to the method and articles formed therefrom are also disclosed.
