8011 Aluminum Foil
8011 Aluminum Foil: Complete Guide to Material Properties, Uses, and Specifications
8011 aluminum alloy is a top-grade material used across packaging, industrial, and pharmaceutical applications. Thanks to its lightweight, corrosion resistance, and excellent formability, this alloy forms the backbone of many aluminum foil products used in daily life.
From food containers and bottle caps to transformer foil and heat-sealing tape, 8011 aluminum foil is trusted for its safety, durability, and adaptability.
🔍 What Is 8011 Aluminum Foil?
8011 aluminum alloy is a non-heat-treatable aluminum grade, primarily made of aluminum (up to 98.9%) with small amounts of iron and silicon to enhance strength. It is widely used to produce industrial aluminum foil, food packaging, pharmaceutical wraps, and household foil.
Why it’s popular:
-
Lightweight and formable
-
Safe for direct food contact
-
High corrosion and moisture resistance
-
Cost-effective and recyclable

🛠 Step-by-Step Guide: How to Choose the Right 8011 Aluminum Foil
Step 1: Determine the application
Is it for food packaging, pharmaceutical use, or industrial sealing?
Step 2: Select the appropriate thickness
Thinner foils (0.014–0.03 mm) are best for flexible wrapping. Thicker foils (>0.05 mm) offer more durability.
Step 3: Pick the right temper
Soft tempers (O) are ideal for wrapping. Hardened tempers (H18, H24) are better for forming and sealing.
Step 4: Request chemical composition and mill test report
Ensure compliance with standards like ASTM or EN.
Step 5: Confirm surface finish and formability
Choose between matte, bright, or embossed finishes depending on branding or technical needs.
