  1. SURFACE ADDITIVES IN PAPER From Process to Performance Enhancing paper quality through surface treatment

  2. Role of Surface Additives in Paper Making Surface additives play a key role in paper manufacturing by improving surface strength, printability, and resistance to water and ink. Applied at the size press or film press, they enhance surface bonding, control absorption, and upgrade final paper performance without changing bulk properties, allowing paper mills to achieve consistent quality and higher-value paper grades.

  3. APPLICATION OF SURFACE ADDITIVES IN THE PAPER MACHINE Surface additives are applied during the paper machine process at the size press or film press, after sheet formation and partial drying. This controlled application allows uniform distribution on the paper surface, improving surface strength, sizing, and functional properties while maintaining stable machine runnability and consistent paper quality.

  4. Surface additives improve specific paper surface properties. Surface sizing additives control water penetration and ink holdout. Surface strength additives enhance fiber bonding and reduce picking and dusting. Functional surface additives improve printability, brightness, smoothness, and barrier performance. Together, they help achieve consistent paper quality and stable machine operation. TYPES OF SURFACE ADDITIVES AND THEIR BENEFITS • Key Points: • Control water absorption and ink holdout • Improve surface strength and fiber bonding • Enhance printability and surface smoothness • Provide functional benefits like moisture and grease resistance

  5. IMPACT OF SURFACE ADDITIVES ON PAPER PERFORMANCE Surface additives have a direct impact on paper performance by improving surface strength, print quality, and resistance to water and ink. They reduce surface defects such as picking and dusting, enhance runnability during printing, and enable consistent surface properties. This results in higher-quality paper, improved end-use performance, and better customer satisfaction.

  6. SURFACE ADDITIVES FOR PAPER QUALITY OPTIMIZATION Surface additives help optimize paper quality by allowing precise control of surface properties such as strength, absorption, and print performance. Their targeted application improves consistency, reduces defects, and enables paper manufacturers to meet specific quality requirements efficiently without altering the internal structure of the paper.

  7. CONCLUSION Surface additives play a vital role in modern paper manufacturing by linking machine processes with final paper performance. Their controlled application at the paper surface improves strength, printability, and resistance to water and ink without affecting bulk properties. By using the right types of surface additives, paper manufacturers can enhance consistency, reduce defects, and develop higher-value paper grades. Overall, surface additives provide a cost-effective and flexible solution for optimizing paper quality, improving machine efficiency, and meeting evolving customer and market requirements across different paper and paperboard applications.
