8011 Alloy 0.02mm High-Temp Resistant Aluminum Foil Roll for Oven Food Container

Aluminum Foil is a super-thin metal sheet made from pure aluminum or aluminum alloys through the rolling process. Due to its unique physical and chemical properties, it is widely used in the food and packaging industries. The advantages of aluminum foil stem from the combination of its metallic properties and its ultra-thin form. The main features are as follows:

Excellent Barrier Property
It can effectively block oxygen, moisture, light, especially ultraviolet (UV) and odor, prevent the contents from oxidizing, getting damp or deteriorating, and extend the shelf life of the product.

Good Thermal Conductivity
High heat conduction efficiency, suitable for food heating (such as oven heating), insulation or freezing, can evenly transfer heat/cold, reduce local overheating or undercooling.

High Ductility
Soft texture, easy to fold and shape, can fit products of different shapes (such as irregular food and electronic components), and is not easily broken after folding, with good sealability.

High Chemical Stability
A dense oxide film naturally forms on the surface of aluminum, which can resist the erosion of most acidic and alkaline substances (except for strong corrosive solutions such as concentrated hydrochloric acid and strong alkali), and will not undergo chemical reactions with ingredients in food. Its safety meets food contact standards (such as FDA, GB 4806).

Lightweight
The density is only 2.7g/cm ³, far lower than metals such as steel and copper. The packaging material made of this material is lightweight, which can reduce transportation costs and has a smaller environmental burden.

Recyclability
Aluminum foil can be 100% recycled and reused, and the energy consumption during the recycling process is only about 5% of the original aluminum production, which is in line with the environmental protection trend and belongs to green packaging materials.

The performance requirements of aluminum foil (such as strength, ductility, corrosion resistance) vary in different fields, and specific alloys need to be matched, as shown in the table below:

The application scenarios and alloy selection of aluminum foil are highly matched: pure aluminum alloys (1235, 1145) focus on flexibility and safety, suitable for flexible packaging of food/medicine; Aluminum iron silicon alloys (8011, 8021) balance strength and ductility, suitable for hard or ultra-thin packaging; Aluminum manganese alloy (3003) is known for its high strength and is commonly used in the industrial field.
