When it comes to pharmaceutical packaging, choosing the right aluminum foil is critical for safety, product stability, and regulatory compliance. Two popular grades are 8011 aluminum foil and 8079 aluminum foil. While both are widely used in PTP blister foil and strip foil, they differ in alloy composition, purity, strength, and barrier properties. Understanding these differences helps B2B buyers, pharmaceutical manufacturers, and packaging converters select the most suitable foil for their production lines.

Alloy Overview: 8011 vs 8079
8011 Aluminum Foil
Type: Al-Fe-Si alloy
Purity: ≥ 98.5% Aluminum
Strength: Medium–High, excellent puncture resistance
Formability: Good for deep drawing
Primary Use: Pharmaceutical blister foil, food packaging, household foil
8079 Aluminum Foil
Type: High-purity aluminum foil
Purity: ≥ 99.7% Aluminum
Strength: Lower than 8011, softer and more ductile
Formability: Excellent for thin, soft foil
Primary Use: High-quality pharmaceutical strip foil, soft blister, foil lamination
Chemical Composition Comparison (Typical %)
| Alloy | Al (%) | Fe (%) | Si (%) | Cu (%) | Others (%) |
|---|---|---|---|---|---|
| 8011 | ≥ 98.5 | 0.6–1.0 | 0.5–0.9 | ≤ 0.05 | ≤ 0.15 |
| 8079 | ≥ 99.7 | ≤ 0.3 | ≤ 0.1 | ≤ 0.05 | ≤ 0.15 |
Key Insight:
8079 foil = ultra-high purity, ideal for sensitive pharmaceutical products
8011 foil = stronger, better for deep-drawn blister containers
Mechanical Properties Comparison
| Property | 8011 Aluminum Foil | 8079 Aluminum Foil |
|---|---|---|
| Tensile Strength | Medium–High | Lower |
| Elongation | Good | Excellent |
| Puncture Resistance | Superior | Moderate |
| Tear Resistance | Superior | Moderate |
| Formability | Very Good | Excellent (ultra-thin) |
Thickness & Processing Capability
| Item | 8011 Foil | 8079 Foil |
|---|---|---|
| Ultra-thin Foil (≤ 7 μm) | Good | Excellent |
| Medium Thickness (8–20 μm) | Excellent | Good |
| Deep Drawing & Container Foil | Strong & stable | Limited |
| Soft Blister Foil | Good | Ideal |
Typical Pharmaceutical Applications
8011 Aluminum Foil
PTP blister foil (light gauge)
Pharmaceutical container foil
Industrial packaging for tablets and capsules
8079 Aluminum Foil
High-purity soft blister foil
Strip foil for sensitive drugs
Laminated pharmaceutical foil for moisture and light barrier
Cost & Purchasing Considerations
| Factor | 8011 Foil | 8079 Foil |
|---|---|---|
| Material Cost | Lower | Higher (ultra-high purity) |
| Processing Cost | Standard | Higher (strict rolling & cleaning) |
| Performance | Strong, good puncture resistance | Soft, ductile, high purity |
| Ideal Use | Deep-drawn blister, container foil | Sensitive pharmaceutical strip, lamination |
Tip for Buyers:
Use 8011 foil for strength-focused pharmaceutical packaging.
Use 8079 foil for ultra-pure, soft strip foil, where drug stability and barrier properties are critical.
International Standards
| Alloy | Common Standards |
|---|---|
| 8011 | ASTM B479, EN 573, EN 546, GB/T 3198 |
| 8079 | ASTM B479, EN 573, EN 546, GB/T 3198 |
Both alloys are widely used in export markets, meeting international pharmaceutical and food-grade requirements.

FAQ
Q1: What is the main difference between 8011 and 8079 aluminum foil?
8011 aluminum foil has higher strength and puncture resistance due to its Al-Fe-Si alloy composition, making it suitable for deep-drawn blister packs and container foil.
8079 aluminum foil is ultra-high purity (≥99.7% Al), softer, and more ductile, ideal for thin pharmaceutical strip foil and laminated blister packaging.
Q2: Which foil is better for pharmaceutical blister packs?
Soft or laminated blister packs: 8079 foil is preferred for its purity, softness, and barrier properties.
Deep-drawn blister containers: 8011 foil is preferred for mechanical strength and puncture resistance.
Q3: Are both foils food and pharma safe?
Yes. Both 8011 and 8079 aluminum foils comply with international food contact and pharmaceutical standards.
Q4: Why is 8079 aluminum foil more expensive than 8011?
8079 foil has higher aluminum purity, requires stricter production and rolling control, and maintains ultra-clean surfaces, leading to higher costs compared to 8011.
Q5: Can 8011 foil be used in soft blister applications?
Yes, but its higher strength makes it less flexible than 8079, which may be required for ultra-thin or laminated pharmaceutical strip foil.
Q6: What thickness ranges are available for 8011 and 8079 foils?
8011 foil: 0.010 – 0.200 mm (deep-drawn blister, container foil)
8079 foil: 0.006 – 0.150 mm (thin strip foil, soft blister foil)
Q7: Can I get customized widths, tempers, and packaging for both foils?
Yes. We offer custom jumbo rolls, slit rolls, and container foil specifications to meet high-speed pharmaceutical production lines and export requirements.
Q8: Do you provide third-party inspection and certificates?
Yes. SGS, BV, or TUV inspections are available. Every shipment includes Mill Test Certificates (MTC) and full traceability documentation.
Q9: Which foil is more suitable for high-speed packaging lines?
8011 foil: Best for deep-drawn blister and rigid containers
8079 foil: Ideal for soft, ultra-thin strip foil, but may not be suitable for deep-drawing
Q10: How to choose between 8011 and 8079 for pharma applications?
Choose 8011 if strength, puncture resistance, and deep-drawing performance are required.
Choose 8079 if high purity, softness, and delicate drug protection are critical.
