Improved Sizing and Machine Efficiency Using a Novel, Simplified Approach, 2021 TAPPICon Live (21TAPL)

Sizing is a critical specification for paper grades across a wide range of industry segments, providing important liquid resistance to the manufactured paper or paperboard. Despite innovations that have occurred over the last few decades, there is still a need to enhance sizing performance and machine efficiency while reducing chemical requirements and minimizing program complexity. To address these needs, this paper outlines the development of a unique alkenyl succinic anhydride (ASA)-based sizing offering which provides best-in-class size performance while simultaneously reducing shipping & inventory logistics. This new technology enables the papermaker to maximize the efficiency of their sizing program while minimizing overall chemical use and simplifying the storage and handling of related size chemistries.
