This study investigates the effects of hot supercalendering on sheets with high filler loadings and polypropylene pulp added. An uncoated sheet that had sheet and optical characteristics similar to a coated number three sheet. was desired. Research was conducted in two stages, handsheet analysis and a machine trial on Western Michigan University's Fourdrinier Pilot Plant. The hot supercalendering of these sheets with 15% Pulpex resulted in a 111% increase in Scott Bond. Unconsolidated Pulpex has no synergestic effects with clay fillers for gloss, brightness, and opacity. Pulpex that has been consolidated does have a synergistic effect with clay for gloss.
