Improve Printability. Enhance Water Resistance. Optimize Paper Quality – Premium Internal Sizing Agents for Papermaking
In modern papermaking, Internal Sizing Agents play a critical role in defining the paper’s surface behavior, particularly its resistance to liquid penetration. These agents are added during the wet-end process to control ink absorption, improve printability, and enhance water resistance—without compromising strength or softness. Whether you’re producing printing paper, packaging board, or specialty sheets, choosing a reliable Internal Sizing Agent Supplier is vital for consistent quality and production efficiency.
At MT Royal, we supply high-performance Internal Sizing Agents suitable for acidic, neutral, and alkaline papermaking systems. Our portfolio includes alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and rosin-based sizing agents, optimized for different fiber types, process conditions, and paper grades. With increasing demand for print-friendly and moisture-resistant paper, our solutions ensure you stay ahead of industry needs.
