8021 Pharmaceutical Aluminium Foil

8021 pharmaceutical aluminium foil is a type of aluminum foil commonly used for pharmaceutical packaging. Like 8011 aluminum foil, it belongs to the 8000 series aluminum foil family and is primarily composed of aluminum and iron. Both 8011 and 8021 aluminium foil play key roles in ensuring pharmaceutical quality and safety.

Specifications of 8021 Pharmaceutical Aluminium Foil

– Thickness:

Common thicknesses range from 0.025mm to 0.08mm. Aluminum foil for blister packaging typically ranges from 0.04mm to 0.065mm. For specialized, high-end pharmaceutical packaging applications, thicknesses can be customized to meet specific needs, ranging from as thin as 0.018mm to as thick as 0.2mm. The choice of thickness depends on the drug’s characteristics, packaging format, and required protective properties. For example, thicker 8021 pharmaceutical aluminum foil may be used for volatile drugs that require a highly sealed storage system.

– Width:

Widths range widely, typically from 100mm to 1600mm, and can be customized to suit different packaging equipment and pharmaceutical packaging dimensions. For example, the automated packaging lines of large pharmaceutical companies may require wider aluminum foil rolls to improve packaging efficiency. Smaller pharmaceutical companies or those with specialized packaging requirements may require custom, narrower aluminum foil widths.

– Temper:

The most commonly used condition is the O state, or annealed state. 8021 pharmaceutical aluminum foil in this state exhibits excellent flexibility and formability, making it easy to process into various complex pharmaceutical packaging shapes, such as the grooves in blister packs and the stamped parts of aluminum-plastic packaging. It is also less susceptible to cracking or excessive thinning during the forming process.

Material Properties of 8021 Pharmaceutical Aluminium Foil:

– Barrier Properties:

It offers exceptional moisture resistance, light blocking, and barrier properties. It effectively blocks moisture, preventing decomposition and deterioration of pharmaceuticals caused by moisture. It also offers 100% light blocking, preventing chemical reactions caused by light and effectively maintaining the chemical stability of pharmaceuticals. It also significantly blocks oxygen, slowing the oxidation process of pharmaceuticals and ensuring their effectiveness throughout their specified storage period. For example, antibiotics that are sensitive to light and moisture can significantly extend their shelf life when packaged in 8021 pharmaceutical aluminum foil.

– Mechanical Properties:

Its robust mechanical properties include high burst, puncture, and tear resistance. This ensures that the foil is impervious to damage during packaging, transportation, and storage, providing reliable physical protection for pharmaceuticals. For example, when handling blister packs containing pharmaceuticals, 8021 pharmaceutical aluminum foil can withstand a certain degree of compression and impact without breaking, thus ensuring the integrity of the pharmaceuticals.

– Safety and Hygiene:

It is safe and non-toxic, fully complying with the regulatory requirements of the FDA and other authorities for materials in direct contact with pharmaceuticals. Rigorous testing has shown that microbial indicators such as bacteria and mold, as well as heavy metal content, are well below regulatory standards. For example, heavy metal content does not exceed 0.25 parts per million. This ensures the safety and hygiene of pharmaceutical packaging, preventing contamination and ensuring patient safety.

– Surface Quality:

The surface is clean, uniform in color, free of blemishes such as mottling and oil stains, and is flat and pinhole-free. This high-quality surface condition not only facilitates subsequent processing such as printing and laminating, but also ensures that the foil’s barrier properties are not compromised. When printing information such as drug names, specifications, and production dates, the smooth surface ensures clearer and more durable printing.

Production Standards of 8021 Pharmaceutical Aluminium Foil

Compliant with various domestic and international standards, including national, American, European, Russian, and Japanese standards, these standards clearly and strictly define the chemical composition, physical properties, and surface quality of 8021 pharmaceutical aluminum foil. For example, the national standard specifies thickness tolerances and mechanical performance indicators, while the American standard has specific processes and standards for material safety and hygiene testing. By strictly adhering to these standards, manufacturers ensure consistent and reliable product quality, meeting the pharmaceutical packaging needs of diverse global markets and customers.

Application Scenarios of 8021 Pharmaceutical Aluminium Foil:

– Blister Pharmaceutical Packaging:

This is one of the primary applications for 8021 pharmaceutical aluminum foil. It is used to package various types of pharmaceuticals, such as capsules and tablets, and is laminated with polyvinyl chloride PVC films or polyvinylidene chloride (PVDC) to form individual blister packaging units. Its excellent barrier properties effectively protect pharmaceuticals from environmental factors. Aluminum foil’s metallic texture and printability enhance the aesthetics of pharmaceutical packaging and facilitate the printing of drug-related information. Tablets such as common cold and fever-reducing medications, as well as capsules like vitamins and fish oil, are often packaged in 8021 pharmaceutical aluminum foil blisters.

– Tropical Pharmaceutical Aluminum Foil (Aluminum-Plastic-Aluminum) Packaging:

Mainly used for high-end pharmaceutical packaging and for pharmaceuticals requiring extremely tight sealing, moisture-proofing, and light-blocking properties. This packaging format incorporates a layer of 8021 cold-stamped aluminum foil over a thermoformed plastic blister and standard PTP aluminum foil. The three-layer structure further enhances the packaging’s barrier properties, making it more resistant to harsh environments such as high temperature and humidity, ensuring consistent drug quality. It is commonly used for packaging valuable pharmaceuticals, biological products, vaccines, and other products requiring demanding storage conditions, for which aluminum-plastic-aluminum packaging provides reliable protection.

– Cold Formed Packaging:

It is used for deep-drawing and is suitable for pharmaceutical packaging with complex shapes, such as multi-chamber blister packs.

– Bag Packaging:

Used for sealing pharmaceuticals such as powders and granules, ensuring storage stability.

8021 pharmaceutical aluminium foil is a key material in the pharmaceutical packaging industry. Produced by manufacturers such as Haomei Aluminum, it offers excellent barrier properties and safety, and is widely used in blister packaging and cold-form packaging.
