High-Performance Aluminium Paste for Can Coatings Gains Global Demand

The global packaging industry is shifting toward higher durability and more visually appealing metal can designs. As a result, aluminium paste for can coatings has become essential for achieving metallic brilliance while maintaining stringent corrosion resistance.

Core Overview: The Role of Aluminium Paste in Can Coatings

Aluminium paste is widely used in beverage cans, food cans, aerosol cans, bottle caps, and metal closures. Its reflective and stable metallic particles create a bright appearance while protecting the substrate from chemical attack.

High-Quality Metallic Performance for Modern Packaging

1. Consistent Brightness and Metallic Orientation

Uniform aluminium flakes create a smooth metallic layer, enhancing:

• Print gloss

• Decorative attractiveness

• Brand visibility

2. Strong Chemical and Sterilization Resistance

Can coatings must withstand:

• Acidic beverages

• Pasteurization

• Retort sterilization

• Carbonation pressure

• Internal corrosion over months or years

3. Optimized for High-Speed Roll and Coil Coating Lines

Modern can manufacturing lines run at 1,800–2,400 cans per minute (industry data: Crown Holdings & Ball Corp. reports).
The aluminium paste must maintain:

• Excellent dispersion

• No screen clogging

• Uniform film formation

• Anti-settling behavior

Applications and Technical Comparison

Main Applications

• Beverage cans (alcoholic & non-alcoholic)

• Food cans

• Aerosol cans

• Chemical cans

• Bottle caps and closures

• Industrial metal packaging

Performance Comparison Table

Market insights from Fortune Business Insights (2024) show that global metal packaging coatings are expected to grow at 4.6% CAGR, driven largely by beverage consumption and premium branding—further increasing demand for aluminium pigments.

Aluminium Paste for Can Coatings

Q1: Is aluminium paste safe for food-contact applications?

Yes. When properly formulated in compliant coatings, aluminium flakes are fully encapsulated and meet food-safe coating regulations.

Q2: Can the aluminium paste withstand sterilization?

Silver Rocket’s can-coating grades are designed for resistance to high-temperature and high-pressure sterilization processes.

Q3: Does the brightness fade over time?

With proper resin systems, the metallic effect remains stable throughout the product’s lifespan.

Q4: Can it be customized based on can manufacturers’ needs?

Yes. Silver Rocket offers OEM formulations with different particle sizes, brightness levels, and resin compatibility.

Q5: Is it suitable for both internal and external coatings?

It is mainly used for external decorative coatings, not internal food-contact protective layers.

Enhance Can Coating Quality with Precision-Engineered Aluminium Paste

Silver Rocket provides high-performance aluminium paste for can coatings, offering superior brightness, stable dispersion, and enhanced chemical resistance for beverage and food packaging applications.
