Abstract
A paperboard, sidewall, and disposable cup made from about 70 wt % to about 100 wt % of recycled fiber. The paperboard can include about 70 wt % to about 100 wt % of recycled fiber, based on the total weight of the fiber. The paperboard can have a board thickness of about 14 mil to about 20 mil, an apparent density of less than about 11.5 lbs/3,000 ft/mil, a CD Taber Stiffness of about 50 g*cm or more, and a MD/CD Taber Stiffness ratio of 1.0 to 3.0, and can be used to make recycled cups having sufficient strength and rigidity properties that rival cups made from virgin fibers.
