How Does PE Wax Improve Scratch Resistance and Durability in Inks?

In the ink industry, surface durability and smoothness are two important factors that determine the quality of printing. Customers in packaging, publishing, and industrial printing require inks that resist scratching, provide consistent gloss, and allow smooth application on different substrates. However, many ink manufacturers face challenges such as weak abrasion resistance, uneven gloss, and insufficient slip. One solution that has been widely adopted in recent years is the use of PE wax in inks.

So, how exactly does PE wax work in inks? When added into the ink formulation, PE wax disperses as fine particles that migrate to the surface during drying. These wax particles create a protective layer that reduces friction and improves slip, helping the printed surface resist scratches and abrasions. At the same time, the protective layer prevents blocking and sticking between printed sheets, ensuring smooth production and handling.

Why is PE wax chosen over other types of additives? Compared with conventional waxes or mineral-based additives, PE wax offers excellent hardness, thermal stability, and compatibility with both water-based and solvent-based ink systems. It provides consistent gloss control, enabling ink producers to balance matte or glossy finishes according to specific requirements. Moreover, PE wax can be used in flexographic inks, gravure inks, offset inks, and digital inks without negatively affecting printability.

Another key advantage of PE wax is its impact on processing. By reducing viscosity and improving pigment dispersion, it helps ink manufacturers achieve better color strength and uniformity. The smoother flow during production minimizes equipment wear, reduces downtime, and improves overall efficiency. This means ink producers not only achieve higher product quality but also save on operational costs.
