8011 cold-formed aluminum foil (alu alu foil), also known as cold-formed foil or cold aluminum blister, is a high-barrier composite material processed by cold stamping and forming process. It is a widely used material for pharmaceutical packaging.

Special structure of cold-formed aluminum foil

Cold aluminum foil is usually composed of multiple layers of materials, including nylon (such as biaxially oriented nylon film BOPA), aluminum foil substrate (such as 8021-O aluminum foil, 8079-O aluminum foil, etc.), polyvinyl chloride (PVC), etc., and may contain components such as outer printing layer, inner printing layer and adhesive.

Characteristics of 8011 cold-formed aluminum foil

High barrier: Aluminum foil 8011 has a highly dense metal crystal structure, which can effectively block gases (such as oxygen, water vapor) and light radiation, providing an excellent protective barrier for products and extending the shelf life of products.

Excellent physical properties: Cold-formed aluminum foil has good tensile strength, yield strength and elongation, can withstand certain pressure and bending deformation, maintain shape stability and durability.

Chemical stability: Alu alu foil has good corrosion resistance and oxidation resistance, and can maintain the stability of its physical and chemical properties under different environments.

Thermal conductivity and thermal insulation performance: Although the thermal conductivity of aluminum foil is high, its use in multi-layer composite materials can effectively regulate heat conduction, which can be used for both efficient heat conduction and thermal insulation applications.

Printing and decoration: The surface finish of cold-formed aluminum foil is high, which is suitable for printing and decoration, and improves the beauty and added value of the product.

Surface characteristics: The surface of 8011 cold-formed aluminum foil is clean, flat and defect-free, which is conducive to subsequent processing and use.

Printing and decoration: Its surface finish is high, which is suitable for printing and decoration, and improves the beauty and added value of the product.

8011 cold-formed aluminum foil has excellent physical properties, mechanical properties, chemical and corrosion resistance, thermal conductivity and insulation properties, and surface characteristics, and has been widely used in many fields.
