Leading Paper Pulp Machine Makers

In paper mills, even a small process disturbance can affect production speed, machine runability, and final paper quality. One common issue that often looks simple but creates major production challenges is foam. Foam may appear during stock preparation, washing, screening, coating, white water circulation, and paper machine operation. If it is not controlled properly, it can slow down drainage, disturb sheet formation, affect surface quality, and reduce machine efficiency. T

Why does deinking sometimes work perfectly one day and struggle the next? In many cases, the answer is simple—temperature. It is one of the most important yet often overlooked factors in recycled paper processing. Even small changes in temperature can directly affect how a Deinking Chemical performs inside the system. Understanding this can help paper mills improve pulp quality, reduce stickies, and maintain consistent production. Why Temperature Matters in Deinking The deink

In the paper industry, print quality depends heavily on how well the paper surface controls ink. One of the most common issues in printing is ink bleeding, where ink spreads uncontrollably into the paper structure instead of staying sharp on the surface. This results in poor print definition, dull colors, and blurred edges. To control this, mills use surface sizing with Cationic Starch , a critical process that improves surface strength and regulates ink absorption. What Caus

When it comes to the sustainability of packaging materials, paperboard is often seen as a reliable, eco-friendly choice. However, not all Paperboard Packaging Solutions are created equal. A key factor that determines the environmental friendliness of paperboard is how it biodegrades over time. The biodegradability of untreated paperboard can vary significantly depending on the environment in which it is placed. For paper mills and companies in the paper industry, understandin

In modern paper manufacturing, maintaining stable wet-end conditions is critical for consistent production and paper quality. One common challenge faced by paper mills is high white water solids. When fibers, fillers, and fines leave the paper sheet and move into the white water system, mills experience raw material loss and unstable machine operation. This is where proper Retention and Drainage control becomes essential. By managing retention and drainage effectively, paper

Internal sizing is supposed to give paper controlled resistance to water, ink, and converting liquids by placing hydrophobes inside the sheet structure. When it fails, the symptoms are predictable: high Cobb, poor HST, edge wicking, ink feathering/bleeding, coating holdout issues, dusting, and unstable runnability due to deposits. Most failures are not “bad chemistry.” They are process-condition mismatches that prevent Internal sizing agents (AKD, ASA, rosin systems, and hyb

Smudging on branded boxes is usually not a “printing problem” alone. It is most often a board + ink + handling + environment problem. Long shipments add heat cycles, humidity swings, vibration, stacking pressure, and repeated rubbing. If the paper packaging board is not matched to the print method and shipping conditions, ink can stay vulnerable and transfer to hands, adjacent packs, or the inside of cartons. Let's break down what actually causes smudging and how to select pa

Foam and trapped air can reduce paper quality and machine efficiency. This blog explains how a dedicated Paper Machine Defoamer offers better performance than generic antifoams and how Paper Machine Deaeration supports stable papermaking operations.

Sheet breaks are a major cause of downtime and production loss in paper mills. Weak fiber bonding, recycled pulp, and uneven sheet strength often lead to frequent breaks during high-speed operations. Dry strength resin helps strengthen internal fiber bonding after drying, improving tensile and burst strength. By using the right dry strength resin for paper, mills can reduce sheet breaks, improve machine runnability, lower waste, and achieve more consistent paper quality acros
