Abstract
Removal of stickies from waste paper and paperboard is obtained with the use of a modified kaolin-based stickies removal composition. The modified kaolin-based stickies removal composition is produced by modifying the kaolin clay, separating the modified kaolin clay from the non-reactive kaolin clay, and then adding a nonionic surfactant to the modified kaolin-based particles. Removal of stickies is improved by the use of this modified kaolin-based stickies removal composition during the recycling of the waste paper and paperboard.
