Paper Quality Improvement

A major paper mill was facing persistent quality issues in its production process, including brightness inconsistency, fiber degradation, and surface defects. These problems led to a high defect rate, frequent reprocessing, and unstable product quality, making it difficult to meet customer quality requirements consistently.

As production volumes increased, maintaining stable paper quality became critical to reducing waste and improving operational efficiency.

Solution

Our Sodium Metabisulfite was incorporated into a customized chemical blend designed to improve process control and fiber stability during paper manufacturing. The solution delivered:

• Effective reduction of oxidative damage to pulp fibers

• Improved brightness control and color stability

• Enhanced fiber strength retention during processing

• More consistent paper formation and surface quality

This optimized chemical blend directly addressed the root causes of paper defects.

Implementation

The solution was implemented over a 4-week period and included:

• Laboratory and pilot-scale trials to optimize dosing levels

• Integration into the existing paper production process

• Close collaboration with mill operators and quality teams

• Continuous monitoring of key quality indicators

Results

After full-scale implementation:

• Paper defects reduced by 40%, significantly lowering waste and reprocessing

• Improved consistency in paper quality across production runs

• Enhanced product stability, meeting tighter customer specifications

• Increased overall production efficiency and customer satisfaction
