Alloy Overview: 8011 vs 1235 Aluminum Foil
8011 Aluminum Foil
8011 aluminum foil is an Al-Fe-Si alloy known for its balanced strength, formability, and cost efficiency. It is one of the most widely used aluminum foil grades in food, pharmaceutical, and packaging industries.
1235 Aluminum Foil
1235 aluminum foil is a high-purity aluminum foil (≥99.35% Al) with excellent ductility and surface cleanliness. It is mainly used in applications where purity, softness, and barrier performance are more important than strength.
Chemical Composition Comparison (Typical, %)
| Alloy | Al (%) | Fe (%) | Si (%) | Others (%) |
|---|---|---|---|---|
| 8011 | ≥ 98.5 | 0.6 – 1.0 | 0.5 – 0.9 | ≤ 0.15 |
| 1235 | ≥ 99.35 | ≤ 0.65 | ≤ 0.10 | ≤ 0.15 |
Key Insight:
1235 foil = higher purity
8011 foil = stronger alloy structure
Mechanical Properties Comparison
| Property | 8011 Aluminum Foil | 1235 Aluminum Foil |
|---|---|---|
| Tensile Strength | Medium–High | Low |
| Elongation | Good | Excellent |
| Puncture Resistance | Better | Lower |
| Tear Resistance | Better | Lower |
| Formability | Very Good | Excellent |
Conclusion:
Choose 8011 when strength and durability matter
Choose 1235 when softness and purity are critical
Thickness & Processing Capability
| Item | 8011 Foil | 1235 Foil |
|---|---|---|
| Ultra-thin Foil (≤ 7 μm) | Good | Excellent |
| Medium Thickness (8–20 μm) | Excellent | Good |
| Deep Drawing | Good | Limited |
| High-Speed Packaging Lines | Stable | Stable (low stress) |
Products Application Comparison
Typical Applications of 8011 Aluminum Foil
Food packaging foil
Pharmaceutical blister foil (PTP base foil)
Household aluminum foil
Container foil (light gauge)
Cable wrap & insulation foil
Typical Applications of 1235 Aluminum Foil
Pharmaceutical packaging (soft blister, strip foil)
Cigarette foil & inner liner
Transformer insulation foil
Capacitor foil
Laminated foil requiring high purity
Cost Comparison & Purchasing Considerations
| Factor | 8011 Foil | 1235 Foil |
|---|---|---|
| Raw Material Cost | Lower | Higher |
| Processing Cost | Standard | Higher (purity control) |
| Scrap Rate | Lower | Slightly higher |
| Overall Cost | ⭐ More economical | Higher |
Buyer Tip:
For large-volume food and household foil orders, 8011 aluminum foil offers the best cost-performance balance.
For pharmaceutical and electrical applications, 1235 foil justifies its higher price due to purity requirements.
International Standards & Availability
| Alloy | Common Standards |
|---|---|
| 8011 | ASTM B479, EN 573, EN 546, GB/T 3198 |
| 1235 | ASTM B479, EN 573, EN 546, GB/T 3198 |
Both alloys are widely accepted in global export markets, including Europe, Middle East, Southeast Asia, and South America.

FAQ
Q1: What is the main difference between 8011 and 1235 aluminum foil?
8011 aluminum foil has higher strength and puncture resistance due to its Al-Fe-Si alloy composition, while 1235 aluminum foil is higher purity (≥99.35% Al), softer, and more ductile, making it ideal for pharmaceutical and electrical applications.
Q2: Which aluminum foil is better for food packaging?
8011 aluminum foil is generally preferred for food containers, household foil, and ready-meal packaging because of its strength, durability, and cost-effectiveness. 1235 foil is used when softness or purity is more important.
Q3: Is 1235 aluminum foil stronger than 8011 foil?
No. 1235 aluminum foil has lower mechanical strength compared to 8011. Its advantage lies in softness, ductility, and high purity, not structural strength.
Q4: Why is 1235 aluminum foil more expensive than 8011?
Because 1235 is high-purity aluminum, production requires stricter raw material selection and processing control, resulting in higher material and manufacturing costs.
Q5: Can 1235 aluminum foil replace 8011 foil in all applications?
No. 1235 is suitable where strength is not critical, such as pharmaceutical blister foil or cigarette inner liners. For food containers and industrial packaging requiring durability and puncture resistance, 8011 is recommended.
Q6: What thicknesses are available for both alloys?
8011 aluminum foil: 0.010 – 0.200 mm (thin household foil to medium container foil)
1235 aluminum foil: 0.006 – 0.150 mm (ultra-thin pharmaceutical foil to soft packaging foil)
Q7: Are both alloys food safe?
Yes. Both 8011 and 1235 aluminum foils comply with international food contact regulations, making them safe for packaging and direct food contact applications.
Q8: Can you provide third-party inspection for 8011 or 1235 foil?
Yes. We accept SGS, BV, TUV, or other third-party inspections. Mill Test Certificates (MTC) are provided with each shipment.
Q9: Do you offer customized width, thickness, and temper for both foils?
Yes. Both 8011 and 1235 aluminum foil can be customized according to your production line and application requirements, including jumbo rolls, slit rolls, and container foils.
Q10: Which alloy is more suitable for high-speed packaging lines?
8011 foil: Excellent for deep drawing and high-speed container production
1235 foil: Suitable for soft, low-stress packaging lines; may not perform as well in deep-drawn containers
