Paper quality is often judged by what you can see and feel—smoothness, print clarity, strength, and how the sheet behaves when it meets ink or moisture. Many of these “end-use” properties are decided at the surface, not in the middle of the sheet. That is where surface additives become essential. They are applied after the paper web is formed to fine-tune performance, reduce defects, and help mills meet grade targets with better consistency. Below you will learn what surface additives do, where they are used in the machine, and why Surface Additives Chemicals are a practical lever for improving paper and board—especially for packaging grades that need strength and protection. What Are Surface Additives in Papermaking? Surface additives are chemicals applied to the paper surface—typically at the size press or film press—after the sheet has already been formed and partially dried. Their job is to modify surface behavior such as: Water absorption and liquid penetration Surfac...

In paper manufacturing, consistent quality depends on smooth stock flow, stable wet-end conditions, and proper control of air and foam. One of the most common yet often underestimated issues in paper mills is poor Paper Machine Deaeration . When entrained air is not effectively removed from the stock, it creates multiple operational and quality problems, including sheet breaks, visible spots, and uneven formation. Understanding how poor deaeration affects the paper machine helps mills take corrective steps using proper deaeration systems and Paper Machine Defoamer solutions. What Is Paper Machine Deaeration? Paper Machine Deaeration is the process of removing entrained and dissolved air from pulp stock, white water, and process streams before they reach critical zones such as the headbox. Air enters the system through agitation, pumping, chemical reactions, recycled fiber processing, and closed water loops. If this air is not removed, it travels with the stock and disrupts flow, ...

Surface Additives are special chemical formulations applied to the outer layer of paper or board to improve how the sheet looks, prints, and performs during converting. They do not change the core structure of the paper; instead, they modify the surface so the final product becomes smoother, stronger, and ready for high-quality printing and packaging applications. Modern paper mills rely on advanced Surface Additives Chemicals to meet customer demands for sharp printing, vibrant colours, and a premium finish suitable for commercial use. Understanding Surface Additives in Simple Words Surface Additives are chemicals that paper mills apply at the size press or coater to improve the top layer of the sheet. Think of them as the “finishing touch” that ensures the paper surface behaves correctly during printing. Without proper Surface Additives, paper may absorb too much ink, appear dull, or develop issues such as feathering, smudging, or uneven print coverage. Surface Additives help crea...

Improving paper quality is not about one single solution—it’s about how different wet-end processes work in harmony. Two of the most important elements in this process are Paper Machine Defoamer and Paper Machine Deaeration . When used together, they help mills achieve smoother operation, better formation, stronger sheets, and fewer defects. Why Foam and Air Are Big Problems in Papermaking Foam creates surface disturbances, overflows, and coating issues. Hidden air inside the pulp causes drainage delays, vacuum overload, and internal sheet defects. To produce consistent, high-quality paper, both problems must be controlled at the same time. That’s where defoaming and deaeration work as a combined system—not separate tools. Role of Paper Machine Defoamer A Paper Machine Defoamer targets visible surface foam. It: Breaks bubbles quickly by lowering surface tension Prevents re-foaming in high-turbulence zones Reduces pinholes, streaks, and formation problems Stabilizes the w...

 In the paper manufacturing industry, every second counts. When machines run efficiently, production stays high, costs stay low, and paper quality improves. However, one common problem that affects efficiency is foam. Foam may look harmless, but it causes major issues during production from uneven sheet formation to machine downtime. That’s where a Paper Machine Defoamer becomes essential. Defoamers are special chemical agents that remove and prevent foam in the papermaking process. We’ll explain how defoamers work, why they’re so important, and how they help paper mills run smoother and more efficiently. What Is a Paper Machine Defoamer? A Paper Machine Defoamer is a chemical additive used to eliminate foam and trapped air during paper manufacturing. Foam forms when air mixes with water and pulp in high-speed machines. This trapped air can interfere with paper formation, drainage, and machine stability. Defoamers work by breaking down foam bubbles and preventing them from fo...

Oxidized starch is a powerful ingredient used in various industries, especially in paper manufacturing, packaging, textiles, and adhesives. With its unique properties like better film formation, reduced viscosity, and improved brightness, oxidized starch has become a preferred choice for industries seeking efficiency and performance. We will explore the top uses of oxidized starch and why it has become a must-have solution for modern manufacturing. What Is Oxidized Starch? Oxidized starch is a type of modified starch that is produced by treating natural starch (from sources like corn or potato) with oxidizing agents such as sodium hypochlorite or hydrogen peroxide. This process reduces its molecular weight and introduces carboxyl and carbonyl groups, making the starch more soluble and functional. The result? A fine, white powder that dissolves easily in water, forms a smooth film, and provides strength and surface improvement to paper and packaging materials.  1. Surface Sizing in ...

 Papermaking is not just about turning wood into sheets. It’s a complex industrial process that requires perfect coordination between machines, water, fibers, and chemicals. One of the most important yet often overlooked parts of this process is the use of drainage chemicals . These special additives play a major role in improving the efficiency and quality of paper production. Drainage chemicals help remove excess water from the pulp on the paper machine. This might sound simple, but better drainage means faster production, better sheet formation, reduced energy use, and consistent paper quality. Without them, mills would face high costs, more downtime, and lower productivity. Let’s dive into the key benefits of using drainage chemicals in industrial papermaking and understand why they are essential in today’s paper mills. 1. Faster Water Removal from Pulp One of the biggest roles of drainage chemicals is to speed up the removal of water during the paper formation process. Wa...
