Abstract
Abstract A method and composition for use in accordance therewith are disclosed for manufacturing top liner and other coated paper products from printed and coated paper and paperboard derived from chemical pulp with conventional paper making equipment. The furnish is pulped in the presence of an effective amount of ethoxylated aliphatic alcohol emulsifier in admixture with a second material selected from the group alkali metal phosphate salt and alkali metal silicate salt. No hydrogen peroxide or other bleaching agent need be present, and no extra washing or ink-separating steps are required. A sheet formed from the released fiber is coated, using a conventional starch coating method, to produce a white top liner or other coated paper product.
