Aluminum foil is widely used in food packaging, pharmaceuticals, insulation, and industrial applications. Among the most common consumer and industrial grades, 8011-O aluminum foil and 8011-H18 aluminum foil are highly sought after due to their excellent corrosion resistance, formability, and cost-effectiveness. Understanding the difference between these two grades is essential for buyers, manufacturers, and engineers to select the right foil for their applications.
In this guide, we explain the soft (O) and hard (H18) temper distinctions, their properties, applications, and provide a clear comparison to help you choose the right foil for your needs.

What is 8011 Aluminum Foil?
8011 Aluminum Foil is part of the 8xxx series, primarily composed of aluminum with small percentages of iron and silicon. It is known for:
Excellent corrosion resistance
High reflectivity
Good formability for packaging applications
Cost efficiency compared to 1xxx or 3xxx series foils
The main difference between 8011-O and 8011-H18 is the temper, which defines the foil's softness or hardness.
8011-O Aluminum Foil (Soft Foil)
Temper: O (Annealed, Soft)
Key Features:
Very soft and highly flexible
Excellent formability for complex shapes
Ideal for wrapping food products and confectionery
Thickness range: 0.006 mm – 0.2 mm
Lightweight and easy to seal
Applications:
Food wrapping (chocolate, bakery, dairy)
Household foil rolls
Blister packaging (medicine/pharma)
Insulation for HVAC
8011-H18 Aluminum Foil (Hard Foil)
Temper: H18 (Full Hard)
Key Features:
Harder and stronger than O temper
Less flexible, higher tensile strength
Retains shape better in industrial applications
Thickness range: 0.02 mm – 0.2 mm
Resistant to tearing under mechanical stress
Applications:
Industrial packaging requiring rigidity
Tube stock for composite cans
Laminated foil for pharma blister packs
Applications requiring structural stability
8011-O vs 8011-H18 Aluminum Foil
| Feature | 8011-O (Soft) | 8011-H18 (Hard) |
|---|---|---|
| Temper | O (Annealed) | H18 (Full Hard) |
| Flexibility | Very high | Low |
| Tensile Strength | Low | High |
| Formability | Excellent | Limited |
| Typical Use | Food wrapping, pharma packaging | Industrial, laminated foil |
| Resistance to Tearing | Low | High |
| Cost | Slightly lower | Slightly higher |
Why the Temper Matters
The temper affects:
Forming ability: O temper foils can easily wrap around irregular shapes.
Strength: H18 foils maintain shape and resist tearing during processing.
Application suitability: Soft foil is perfect for flexible packaging; hard foil is ideal for structural uses.

faq
Q1: What is the main difference between 8011-O and 8011-H18 aluminum foil?
A1: The difference lies in the temper. 8011-O is soft and highly flexible, ideal for food and pharmaceutical packaging. 8011-H18 is hard and strong, suitable for industrial and laminated applications.
Q2: Can 8011-O foil be processed into H18 foil?
A2: Yes, 8011-O can be cold-rolled and processed into H18 temper to increase hardness and tensile strength.
Q3: Are both 8011-O and H18 foils FDA-approved for food contact?
A3: Yes, both foils meet FDA and international food-grade standards when sourced from certified manufacturers.
Q4: Which foil is better for pharmaceutical blister packs?
A4: Both can be used, but H18 foil provides higher mechanical strength for machine processing, while O temper is preferred when extreme flexibility is needed.
Q5: What thickness and width ranges are available for 8011 foils?
A5: Thickness ranges from 0.006 mm to 0.2 mm, and widths can be customized per client requirements. Both O and H18 tempers are available in rolls or sheets.
Q6: How do I choose between soft and hard 8011 foil?
A6: Choose O temper for high flexibility and wrapping applications. Choose H18 temper for strength, structural stability, and industrial applications.
Q7: Is 8011-H18 foil suitable for household use?
A7: H18 foil is less flexible and generally not ideal for manual wrapping. It's better for industrial or laminated packaging.
Q8: What quality certifications are available?
A8: We provide ISO 9001, SGS, and FDA certifications, including third-party testing reports for thickness, tensile strength, and pinhole control.
Q9: Can I order custom thickness, width, or temper?
A9: Yes, we offer customized solutions to meet your specific packaging or industrial needs.
Q10: How fast is international shipping?
A10: We provide fast and reliable global shipping, optimized for bulk B2B orders, with protective packaging to prevent damage.
