Why 8011 Aluminum Foil is the Ideal Material for Bottle Cap Packaging

8011 aluminum foil for anti-theft cap closure is the preferred material in the bottle cap packaging industry. It is typically processed with coating, printing, and lamination, and is widely used in ROPP (Roll-on Pilfer Proof) caps for wine bottles, beverage bottles, cosmetic containers, and pharmaceutical bottles.

This foil not only provides airtight sealing and protection but also enables one-time opening and tamper-evident functionality, effectively preventing re-sealing and counterfeiting.

What is 8011 Cap Closure Foil?

8011 is an alloy from the 8xxx aluminum series, commonly used in packaging applications. With added iron and silicon, it offers enhanced tensile strength, corrosion resistance, and formability.

• Common tempers: O, H14, H16, H18, H24 (selected based on forming requirements)

• Typical thickness: 0.018 mm – 0.2 mm (based on cap sealing needs)

Key Features of 8011 Aluminium Foil for ROPP Cap:

• Moisture-resistant

• Non-toxic and odorless

• Food-grade hygiene

• Excellent formability

• Lightweight and recyclable

• Highly decorative surface for branding

• Strong barrier properties, extending product shelf life

• Clean surface with no oil stains or indentations

• Adaptable to high-speed automatic punching lines

Mechanical Properties of 8011 Cap Foil:

Test standards: Autoclave test, HgCl₂ resistance test

Tensile strength: 130–155 MPa

Earring rate: Max 2%

Packaging: Export-standard wooden crates

Broad Applications of 8011 Aluminum Bottle Cap Material:

1. Alcohol Packaging

Widely used in packaging of liquor and wine bottles. Its excellent barrier properties preserve the quality of the contents, while its attractive appearance enhances brand image and product value.

2. Cosmetic Packaging

With superior moisture resistance and light-blocking capabilities, it is an ideal choice for cosmetic container seals.

3. Pharmaceutical Packaging

8011 aluminum foil is also highly valued in pharmaceutical applications due to its food-grade safety, clean de-oiling, minimal pinholes, good flatness, and excellent deep-drawing performance, ensuring safety and reliability in medicine packaging.

4. Other Uses

It is also extensively used for milk powder lids, beverage caps, and yogurt foil lids, fulfilling a variety of packaging needs across industries.
