The papermaking industry relies on a variety of chemical additives to enhance the quality and performance of paper products. Carboxymethyl Cellulose Sodium (CMC) powder, a key product offered by NINGBO INNO PHARMCHEM CO., LTD., is highly valued for its ability to significantly improve paper strength, surface smoothness, and printability. As both a sizing agent and a smoothing agent, CMC contributes to the creation of superior paper products, from everyday printing paper to specialized packaging materials.

In papermaking, CMC powder is added to the pulp slurry during the manufacturing process. Its primary functions include improving internal bonding between fibers and acting as a surface additive. When used as an internal sizing agent, CMC enhances the paper's resistance to liquids, preventing ink feathering and improving print definition. This property is critical for high-quality printing papers and packaging that require resistance to moisture and grease. The effectiveness of CMC as a paper smoothing agent is also noteworthy.

Research indicates that adding even small amounts of CMC, typically 0.1% to 0.3%, can lead to substantial improvements in paper characteristics. For instance, it can increase tensile strength by 40% to 50%, boost compression fracture resistance by 50%, and enhance surface smoothness significantly. This translates to stronger, more durable paper that handles better and provides a superior printing surface. Manufacturers seeking to buy CMC for papermaking applications can achieve these remarkable improvements by incorporating the right grade of CMC.

NINGBO INNO PHARMCHEM CO., LTD. supplies specialized grades of CMC powder designed to optimize these papermaking processes. Their products ensure excellent dispersion in the pulp and provide consistent performance, leading to improved efficiency and product quality. The company’s commitment to providing high-purity CMC powder makes it a reliable partner for paper mills aiming to enhance their product offerings. Whether it's for printing paper, packaging, or specialty papers, the role of CMC is indispensable.

The application of CMC powder in papermaking exemplifies its versatility as a functional additive. By improving mechanical strength and surface properties, CMC contributes to the creation of high-performance paper products that meet the diverse demands of the market. NINGBO INNO PHARMCHEM CO., LTD. is dedicated to supporting the papermaking industry with innovative CMC solutions that drive quality and efficiency.
