The evolution of paper sizing technologies has seen significant advancements, with Alkyl Ketene Dimer (AKD) wax emerging as a leading innovation. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-quality AKD wax that offers distinct advantages over older sizing agents, catering to the industry's demands for better performance, greater efficiency, and enhanced sustainability.

Traditionally, rosin-alum sizing was the prevalent method for imparting water resistance to paper. However, this system operated under acidic conditions, which had several drawbacks. Acidic environments can lead to paper degradation over time, limit the use of alkaline fillers like calcium carbonate, and are generally less environmentally friendly. AKD wax, conversely, functions optimally in neutral to alkaline pH ranges (pH 7-9). This shift to neutral/alkaline sizing offers multiple benefits: it preserves paper integrity, allows for cost-effective fillers, and is more conducive to modern, eco-friendly papermaking practices.

The innovation offered by AKD wax also lies in its reactivity and the nature of the hydrophobic barrier it creates. Unlike some older sizing agents that could be less stable or prone to hydrolysis under varying conditions, AKD forms a strong covalent bond with cellulose fibers. This covalent linkage results in more permanent and robust hydrophobicity, ensuring that the paper maintains its resistance to liquids even after prolonged exposure or under challenging conditions. The improved water resistance directly translates to better printability, reduced ink feathering, and enhanced dimensional stability for the paper.

Furthermore, AKD wax enables efficient surface sizing as well as internal (in-pulp) sizing. This dual capability allows manufacturers to achieve a comprehensive level of water resistance tailored to specific product needs. The ability to form stable emulsions is also a key innovation, simplifying the application process and ensuring uniform distribution of the sizing agent across the paper web. NINGBO INNO PHARMCHEM CO.,LTD. ensures their AKD wax products are formulated for ease of use and maximum efficacy.

The environmental advantages of AKD wax further cement its status as an innovative solution. Its compatibility with eco-friendly fillers and its role in producing safe food packaging paper align with global sustainability trends. By choosing AKD wax, paper manufacturers are not only improving product performance but also contributing to a greener and safer industry. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing innovative AKD wax solutions that drive the future of paper sizing.
