The paper industry relies on a complex array of chemicals to achieve the desired quality and performance characteristics of its products. Among these, aluminum sulfate holds a pivotal position, particularly in the process of paper sizing. As a premier supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing paper manufacturers with high-quality aluminum sulfate that significantly contributes to improved paper formation, enhanced strength, and efficient sizing. This article explores the critical functions of aluminum sulfate in the paper industry and highlights why partnering with a reliable manufacturer like us is crucial.

Paper sizing is a fundamental process aimed at controlling the absorption of liquids, such as ink or water, into the paper. Historically, acid sizing using rosin and alum (aluminum sulfate) was prevalent. While neutral or alkaline sizing methods are now common, aluminum sulfate still plays a vital role, especially in certain formulations and for achieving specific paper properties. It helps in the precipitation of rosin size onto the cellulose fibers, creating a hydrophobic surface that limits liquid penetration. This results in sharper print quality and reduced ink feathering, essential for high-grade printing and writing papers. Exploring aluminum sulfate paper industry sizing is key to understanding modern paper production.

The benefits of using quality aluminum sulfate in paper manufacturing extend beyond just ink resistance. It also contributes to the overall strength and integrity of the paper sheet. By promoting better interfiber bonding, it can enhance the tensile strength and stiffness of the final product. Furthermore, the consistency of our aluminum sulfate, with its guaranteed AL2O3 content, ensures predictable results in the sizing process, minimizing batch-to-batch variations and optimizing production efficiency. NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of consistent quality for manufacturers who buy aluminum sulfate flocculant.
