8011 O Temper Aluminum Foil Jumbo Roll
Nowadays, there are many package materials in our daily life. Common packaging includes plastic bags, cartons and so on. With the development of technology, metal packaging appeared. The most popular metal packaging is aluminum foil packaging. Aluminum foil takes aluminum alloy as material, and it has applications in food and medicine packaging.
At present, 8011 aluminum foil is the first choice for many people. It adds Al-Fe-Si element. The alloy properties of more than 1% of the total alloying elements have corresponding advantages. The common material tempers include O, H14, H16, H18 etc.
Different Types of 8011 Aluminum Foil Products
Depending on your industry, the 8011 alloy can be customized into various types. Each type serves a unique purpose based on its thickness and surface treatment.
1. Household Aluminum Foil Jumbo Rolls
This is the most common type for kitchen foil. It is in thicknesses ranging from 0.008 mm to 0.02 mm. It is safe for food contact and provides an excellent barrier against light and moisture.
2. Pharmaceutical Foil (Blister Foil)
In the medical field, safety is the priority. 8011 O foil has uses for the “push-through” part of pill packs. It is typically laminated with other materials to ensure a sterile environment for medicine.
3. Container Foil
If you manufacture disposable food trays or airline meal boxes, you need a slightly thicker version of the 8011 alloy.
4. Lidding Foil
Used for yogurt cups, milk bottles, and coffee pods. It is usually coated with a heat-seal lacquer on one side to ensure a leak-proof seal.
Comparing 8011 with Other Common Alloys
Choosing the right alloy is essential for cost-efficiency and performance. Here is how 8011 compares to other popular options like 1235 and 3003.
| Feature | 8011 Alloy | 1235 Alloy | 3003 Alloy |
|---|---|---|---|
| Strength | High | Low | Very High |
| Flexibility | Excellent | Very High | Medium |
| Common Use | Household & Pharma | Flexible Packaging | Containers & HVAC |
| Cost | Mid-range | Economical | Higher |
| Durability | Good | Fair | Excellent |
Why choose 8011 over 1235?
While 1235 has a higher aluminum content (over 99.35%), it is much softer. 8011 contains more iron and silicon, which gives it better mechanical strength. If your packaging needs to resist tearing, 8011 O is the better choice.
Classification by Thickness
We categorize our jumbo rolls into three main thickness grades. Each grade is suited for different manufacturing processes.
Light Gauge Foil (6−9 microns)
- Applications: Lamination with paper or plastic, cigarette packaging, and milk carton linings.
- Key Feature: Extremely thin but provides a complete light barrier.
Medium Gauge Foil (10−25 microns)
- Applications: Household foil rolls, hair salon foil, and chocolate wrapping.
- Key Feature: Versatile and easy to handle for consumer-level products.
Heavy Gauge Foil (>25 microns)
- Applications: Semi-rigid containers, industrial heat shields, and cable wrapping.
- Key Feature: High structural integrity and heat resistance.
Core Application Fields
The versatility of 8011 O Temper Aluminum Foil Jumbo Roll allows it to be in numerous sectors. Here is a detailed look at where this product excels:
Food Packaging and Service
- Catering: Used in hotels and restaurants to keep food warm and moist.
- Baking: Protects pie crusts and meats from over-browning in the oven.
- Snack Packaging: Laminated with plastic to keep chips and nuts crispy.
Medical and Healthcare
- Pill Blisters: Provides a barrier against oxygen and moisture to extend shelf life.
- Surgical Equipment: Used in sterile packaging for sensitive medical tools.
Industrial Applications
- Cable Shielding: Wrapped around power and communication cables to prevent electromagnetic interference.
- HVAC Systems: Used in air conditioning heat exchangers for efficient heat transfer.
- Building Insulation: Reflects radiant heat in roofs and walls to save energy.
The Production Process: From Ingot to Jumbo Roll
To ensure the high quality of our 8011 O foil, we follow a strict manufacturing process:
- Melting and Casting: Aluminum ingots are melted with specific amounts of Iron (Fe) and Silicon (Si).
- Cold Rolling: The aluminum is through heavy rollers to reduce its thickness.
- Intermediate Annealing: The foil is heated to maintain workability.
- Finish Rolling: The foil reaches its final thickness (e.g., 0.01 mm).
- Annealing (O Temper): The final jumbo roll is in an oven for a long period. This “softens” the foil to the O temper state.
- Slitting and Testing: The roll is trimmed to the customer’s required width and tested for pinholes and tensile strength.
Quality Indicators for Jumbo Rolls
When you receive a jumbo roll, how can you tell it is high quality? Look for these four indicators:
- Wetting Tension: High-quality foil should have a high surface tension so that inks and glues can stick to it easily.
- Pinhole Count: For food and pharma, the number of tiny holes (pinholes) must be near zero to ensure a perfect barrier.
- Flatness: The roll should be wound evenly. If the edges are wavy, it will cause problems during the unwinding process.
- Surface Cleanliness: There should be no residual rolling oil. If there is oil, the foil might smell bad or fail to bond with other materials.
What is 8011 O Temper Aluminum Foil?
The term 8011 refers to the alloy series. It is an aluminum-iron-silicon alloy to offer better tensile strength and elongation compared to pure aluminum.
The O temper indicates that the foil has undergone a full annealing process. This makes the foil very soft, flexible, and easy to bend or wrap around products. When you buy a jumbo roll, you are getting a large, continuous roll of foil into smaller rolls or specific packaging shapes.
Key Technical Specifications
To help you understand the physical properties, here is a breakdown of the standard specifications for our jumbo rolls:

Application
Take the application of 8011 aluminum foil in the pharmaceutical packaging industry as an example. In medicine industry, most of pills, tablets and other drugs all adopt aluminum plastic blister packaging method. The packaging has light weight, low cost, and can effectively guarantee the quality of products. Therefore, it’s the ideal choice for pharmaceutical companies.
Due to the advanced technology, pharmaceutical aluminum foil has more mature production technique. Meanwhile, the quality of medicine aluminum foil is also constantly improving.
