8011 / 3003 Aluminum Foil Jumbo Roll for Food Packaging Raw Materials
In the field of food packaging, aluminum foil has become an indispensable base material due to its excellent barrier performance, thermal conductivity, and formability. In the industrial raw material market, 8011 aluminum foil and 3003 aluminum foil are two of the most widely used types.
Product Introduction
8011 aluminum foil belongs to the Al-Fe-Si alloy series. It features excellent pinhole resistance, outstanding elongation, and dense barrier performance. It can completely block light, moisture, oxygen, and particles, making it an ideal choice for moisture-proof and aroma-preserving packaging. Its surface water-brush test usually reaches Grade A, ensuring high peel strength when laminated with PE, PET, and other films.
3003 aluminum foil belongs to the Al-Mn alloy series. As a typical anti-rust aluminum material, 3003 aluminum foil contains manganese, which gives it significantly higher mechanical strength and hardness than 8011. It is not easy to deform during baking, heating, or high-temperature sterilization. At the same time, it has excellent deep drawing performance, and the edges are less likely to crack during stamping.
In highly automated modern packaging production lines, “downtime for roll replacement” is one of the main causes affecting production capacity and increasing material loss. The 8011 and 3003 aluminum foil jumbo rolls we supply directly feature large single-roll weight, very few joints, and strong cores. They are specially designed for high-speed laminating machines, slitting machines, and stamping machines.
Performance Advantages of 8011 / 3003 Aluminum Foil
1. Excellent Barrier Performance
Effectively blocks oxygen, moisture, light, and odors, helping extend the shelf life of food.
2. Food-Grade Safety Standards
Meets the requirements for food contact materials, does not release harmful substances, and is safe and reliable.
3. Good Formability
Suitable for deep drawing, folding, and high-speed stamping processes, and compatible with various food containers.
4. Environmentally Friendly and Recyclable
Aluminum can be 100% recycled, meeting the development trend of green packaging.
Typical Application Fields
8011 / 3003 aluminum foil jumbo rolls are widely used in the following fields:
Disposable food containers and airline meal packaging
Bakery food packaging, such as cakes, bread, and biscuits
Frozen food packaging
Chocolate and candy packaging
Fast food and takeaway aluminum foil containers
Industrial composite packaging materials, such as paper-aluminum laminates and film-aluminum laminates
Production Process of Aluminum Foil Jumbo Rolls
The production process of aluminum foil jumbo rolls mainly includes:
1. Melting and Cast Rolling
Ensures uniform and stable alloy composition.
2. Multi-Pass Cold Rolling
Gradually rolls the material to the target thickness, usually 6–50 microns.
3. Annealing Treatment
Improves ductility and food-grade performance.
4. Slitting and Rewinding
Forms standard jumbo roll specifications.
5. Quality Inspection
Includes inspection of thickness tolerance, pinhole rate, tensile strength, and surface cleanliness.
Company Profile
We are a comprehensive manufacturing enterprise specializing in the research, development, production, and export of aluminum and aluminum processed materials. Our products cover food packaging aluminum foil, industrial aluminum strip, aluminum sheet, and deep-processed aluminum materials.
The company is equipped with advanced aluminum foil rolling production lines and slitting equipment, with stable large-scale supply capacity. Our products are widely exported to Europe, the Middle East, Southeast Asia, and South America.
Our Product Advantages
Food-Grade Clean Surface, Free from Oil Stains
Advanced online annealing technology is adopted to ensure that the aluminum foil surface is clean and free from black spots, oil stains, and scratches. The Grade A water-brush performance ensures optimal adhesion of lamination glue or coating in subsequent processes, preventing delamination or peeling.
Extremely Low Pinhole Rate
Pinholes are the biggest enemy of barrier performance. Through vacuum melting and high-precision rolling mill control, we reduce micron-level pinhole rates to far below national standards, helping extend the storage life of packaging by more than 30%.
Perfect Flatness and Coil End Face
For jumbo rolls, layer shifting and “bird nest” defects are major concerns. Our fully automatic winding system ensures neat coil end faces with layer deviation of less than 0.5 mm and uniform tension. The foil runs smoothly on customers’ high-speed unwinding machines without breakage or vibration.
FAQ
Q1: What is the difference between 8011 and 3003 aluminum foil?
8011 focuses more on ductility and forming performance for food packaging, making it suitable for food containers and direct food contact packaging. 3003 has higher strength and is more suitable as a structural material for composite packaging.
Q2: Can aluminum foil jumbo rolls be customized?
Yes. Customized thicknesses, widths, inner diameters, and surface treatments are available. Slitting services can also be provided according to customer equipment requirements.
Q3: Does the product meet food-grade standards?
Yes. The product meets the requirements for food contact materials and can be used for direct or indirect food packaging applications.
Q4: What is the minimum order quantity?
The MOQ can be flexibly adjusted according to specifications and thickness. Trial orders and long-term cooperation orders are both supported.
Q5: Is export packaging available for aluminum foil?
Yes. Standard export wooden pallet or wooden case packaging is available to ensure safe long-distance sea and air transportation.
Q6: What is the usual delivery time?
Usually 15–30 days, depending on order specifications and quantity.
Q7: Can you provide quality inspection reports?
Yes. We can provide Material Test Certificates, factory inspection reports, and third-party inspection documents if required.
