The challenge
A testliner producer in Southern Europe wanted to upgrade the testliner quality, for which a 15% increase in burst index was required. The strength of the standard testliner grade is normally controlled by adding 12 kg/ton cationic starch. However, further increase in the starch dosage had only limited effect on strength, not more than a 10% increase in burst.
The solution
Kemira's new strength aid FennoBond® 3300E was added to the suction side of the machine chest pump in addition to 12 kg/ton cationic starch. FennoBond 3300E is a solution polymer with a high cationic charge, making it less sensitive to anionic trash and high conductivity compared to traditional strength aids.
The benefits
At 15 kg/ton of FennoBond 3300E, the burst index increased by 15% on average, allowing for quality upgrade of the testliner that can be sold at a higher price. Furthermore, the cationic demand in the headbox was also reduced. No issues with machine runnability or other paper qualities. The net profit was estimated at 10-15 €/ton of paper.
Key benefits
Quality upgrade allowing to charge a higher price for improved testliner
