Wax Additives for Can Coatings: Ensuring Safety and Durability from Inside Out

Can coatings, whether for beverages, food, or aerosols, serve as a critical barrier between the container and its contents. They must endure aggressive filling processes, storage, transportation, and even sterilization—without compromising safety or visual appeal.

Micronized wax powders are used in both internal and external can coatings to improve scratch resistance, reduce coefficient of friction, and maintain clean surface appearance during high-speed production. In exterior lacquers, waxes also prevent scuffing during transportation.

In interior coatings, FDA-compliant waxes such as specific grades of polyethylene or oxidized wax are used in minimal dosages to ensure safety while improving processability and reducing sticking to machinery.

Advantages of Wax Use:

• Enhanced abrasion and scuff resistance

• Improved anti-blocking and stacking performance

• Increased line speed compatibility due to better slip

• Long-term visual retention of cans in retail environments
