🧑💼 Customer Background
Company: A paper group in India
Location: Kalimantan, Indonesia
Main Products: Coated paper, white cardboard, thermal paper
Annual Output: ~180,000 tons
A paper group in India is a mid-sized paper manufacturer with a strong export business to Southeast Asia and the Middle East. The team had been seeking a coating solution to enhance smoothness and print adaptability for premium paper applications.
❗ Challenges Faced
The company relied heavily on GCC (ground calcium carbonate) as the primary filler. However, they encountered:
Insufficient surface smoothness, limiting print quality
Uneven ink absorption, leading to inconsistent client feedback
High processing costs due to increased energy use in pulping and coating
Several alternative fillers were trialed, but none struck the right balance between quality and cost.
Xufeng proposed XT-1011, a coating-grade talc powder optimized for papermaking, with these benefits:
Ultra-fine particle size (D90 ~6μm) for better surface coverage
High whiteness (≥95%), maintaining brightness and opacity
Low oil absorption, improving flow and coating lubrication
Excellent dispersion, reducing pulping energy consumption
We recommended replacing 20% of GCC with XF-Talc620 and provided minor formulation tweaks to rebalance additives and binders.
After three weeks of production testing, A paper group in India reported strong performance gains:
✅ Surface smoothness improved by ~30%, allowing higher-end print jobs
✅ Coating energy consumption reduced by ~18%
✅ Overall formulation cost dropped by ~9% without affecting optical properties
✅ Customer complaint rate on export shipments decreased by 45%
“At first, we were hesitant to change the filler, worried it might affect print quality. But Xufeng’s team delivered a well-balanced solution. Surface quality is better, and even our machines are running more smoothly. We’re planning to apply XT-1011 across more product lines.”
