Sizing applications are critical to the papermaking process and help provide desired functionality to the finished paper/paperboard. For example, sizing is useful for printing & writing grades to control the penetration of water-soluble inks, while in board grades sizing can help a cardboard box maintain its integrity when incidentally exposed to water.   

NALSIZE ASA is an internal sizing technology that delivers stable, controllable, on-machine sizing.  This technology also helps to optimise surface sizing programme requirements and reduce size press breaks. When combined with Nalco Water’s other wet-end offerings including METRIX™ strength portfolio and retention and drainage programmes, NALSIZE ASA technologies has the ability to optimise end-product performance and machine efficiencies.
