In today’s bottle packaging industry, caps are more than just sealing components—they are integral to brand expression, anti-counterfeiting, and user experience. Designed specifically for screw caps, ROPP closures, and press-on caps, 8011 aluminum closure sheets are widely used in wine, beverages, pharmaceuticals, food, and personal care products due to their excellent formability, coating adhesion, and printability.

What Are 8011 Printed Aluminum Closure Sheets?

8011 aluminum alloy is an Al-Fe-Si-based alloy in the 8000 series, known for its good formability, corrosion resistance, and anodizing ability. When processed into closure sheet form, and further treated with pre-coating, printing, and stamping, it becomes an ideal material for premium cap manufacturing.

8011 aluminum foil features a clean, pinhole-free surface, meeting food and pharmaceutical safety standards.

Printed aluminum closure sheets refer to aluminum sheets that have undergone multi-color printing, hot stamping, foil transfer, and varnish coating, helping brands establish strong visual identity and elevate product packaging.

These sheets maintain a flat surface, free from roll marks or stains, ensuring sharp, high-quality print graphics. Complex designs can be applied using curved-surface printing technology, and surface varnish improves ink durability.

Why Choose 8011 Aluminum for Cap Production?

1. Excellent Stamping & Deep Drawing Performance

8011 aluminum offers superb elongation, resisting cracking during stamping and avoiding spring-back in deep drawing, ideal for high-speed bottle cap production lines.

2. Outstanding Surface Coating Compatibility

Its surface readily supports multi-color offset printing, UV printing, hot stamping, embossing, and laser coding with clear patterns and strong adhesion.

3. Food-Safe & Corrosion-Resistant

8011 aluminum is non-toxic and odorless. When paired with BPA-free and alcohol-resistant coatings, it complies with food, beverage, and pharmaceutical packaging standards.

4. High Airtightness & Seal Integrity

When used in precision capping systems, 8011 closures form airtight seals with both glass and plastic bottles, effectively preventing leakage, oxidation, and aroma loss.

Application Scenarios

• Wine & Spirits Caps: Replaces corks in red and white wine closures. Offers better cost efficiency and recyclability.

• Pharmaceutical Bottle Closures: Withstands high-temperature sterilization, thoroughly degreased to ensure medicine safety.
