8011 Aluminum Foil Supplier
Choosing a professional 8011 aluminum foil supplier is the first step toward ensuring the quality of your packaging or industrial products. The $$8011$$ alloy is one of the most widely used aluminum products in the world. It is known for its versatility, strength, and excellent barrier properties.
Whether you are in the food industry, pharmaceutical sector, or industrial manufacturing, high-quality 8011 aluminum foil provides the protection your products need.
What is 8011 Aluminum Foil?
The $$8011$$ alloy is a typical aluminum foil alloy. It belongs to the $$8000$$ series of aluminum alloys, which contains higher levels of iron and silicon. These elements give the foil better strength and corrosion resistance compared to pure aluminum alloys like the $$1000$$ series.
As a leading 8011 aluminum foil supplier, we ensure our foil meets international standards. It is non-toxic, tasteless, and safe for direct contact with food and medicine.
Technical Specifications and Chemical Composition
Understanding the chemical makeup of the foil helps you understand its performance. The iron ($$Fe$$) and silicon ($$Si$$) content in $$8011$$ alloy makes it more durable than other foils.
Table 1: Chemical Composition of 8011 Alloy
| Element | Percentage (%) |
|---|---|
| Silicon ($$Si$$) | $$0.50$$ – $$0.90%$$ |
| Iron ($$Fe$$) | $$0.60$$ – $$1.0%$$ |
| Copper ($$Cu$$) | $$\le 0.10%$$ |
| Manganese ($$Mn$$) | $$\le 0.20%$$ |
| Magnesium ($$Mg$$) | $$\le 0.05%$$ |
| Zinc ($$Zn$$) | $$\le 0.10%$$ |
| Aluminum ($$Al$$) | Remainder |
Common Tempers (States) of 8011 Foil
The “temper” refers to the hardness or flexibility of the aluminum foil. Depending on your machine and application, you might need a very soft foil or a rigid one.
Table 2: Temper and Mechanical Properties
| Temper | State | Features | Best Use Case |
|---|---|---|---|
| O | Annealed (Soft) | Very flexible, easy to wrap | Food wrapping, lamination |
| H14 | Work Hardened | Moderate strength | Bottle caps, closures |
| H18 | Fully Hard | High strength, stiff | Blister packaging, industrial |
| H22 | Semi-Hard | Balanced flexibility | Food containers |
| H24 | Partially Annealed | Good ductility | Semi-rigid containers |
Different Types of 8011 Aluminum Foil Products
We offer several types of 8011 aluminum foil to suit different industry needs. Each type has a specific thickness and surface finish.
1. Household Aluminum Foil
This is the most common type found in kitchens. It has uses for cooking, freezing, and wrapping food. It is usually supplied in “O” temper to make it easy to fold.
- Thickness: $$0.008$$mm to $$0.02$$mm.
- Surface: One side bright, one side matte.
2. Pharmaceutical Blister Foil
This foil is used to protect pills and capsules. It provides a perfect barrier against moisture, light, and oxygen.
- Thickness: $$0.02$$mm to $$0.03$$mm.
- Temper: H18 (Hard).
- Coating: Usually coated with a heat-seal lacquer.
3. Food Container Foil
Used for making takeaway boxes and airline meal trays. It must be strong enough to hold its shape.
- Thickness: $$0.03$$mm to $$0.08$$mm.
- Temper: H22 or H24.
- Features: Lubricated for easy deep-drawing.
4. Bottle Cap and Closure Foil
This is used for wine bottles, medicine bottles, and milk caps. It is often lacquered or printed.
- Thickness: $$0.15$$mm to $$0.23$$mm.
- Alloy: $$8011$$ is preferred over $$1235$$ here for its higher strength.
5. Heat Sealing Foil (Lidding Foil)
Commonly found on yogurt cups and coffee pods. It is laminated with plastic films like PE, PET, or PP.
- Structure: Foil + Heat Seal Layer.
