What is medicinal aluminum foil?
Medicinal aluminum foil plays a pivotal role in the pharmaceutical industry and is a key packaging material for various pharmaceuticals. Its versatility, protective properties and ease of use make it an integral component in ensuring the safety, effectiveness and longevity of pharmaceutical products.
Characteristics of medicinal aluminum foil
Material composition: Medicinal aluminum foil is usually made of pure aluminum alloy with small amounts of other metals such as manganese and magnesium. This alloy gives the foil the necessary strength and flexibility while maintaining its inherent corrosion resistance and inertness.
Thickness: The thickness of pharmaceutical aluminum foil is a critical parameter as it directly affects its barrier properties. Foil thickness is typically 20 to 30 microns, but variations can be made to meet specific packaging requirements.
Barrier properties: One of the most important properties of pharmaceutical aluminum foil is its excellent barrier properties. It effectively protects medicines from moisture, oxygen, light and pollutants, ensuring the stability and shelf life of medicines.
Printability: Pharmaceutical foils are designed to be easily printed, allowing basic product information such as dosage instructions, batch numbers and expiration dates to be printed directly on the foil.
Heat-sealability: These foils are heat-sealable, ensuring they seal securely to all types of packaging materials, including plastic, glass and cardboard.
Medicinal foil applications
Medicinal aluminum foil is used in various areas of the pharmaceutical industry:
Blister packaging: Blister packaging is commonly used for tablets and capsules. The foil creates a barrier between the drug and external factors, ensuring product integrity.
Strip Packaging: This packaging format is used in oral film strips and is ideal for individual dosing. Aluminum foil ensures hygiene and protection of these delicate products.
Sachets: Medicinal sachets are typically used for granules or powders, utilizing the barrier properties of aluminum foil and the convenience of single-dose packaging.
Ampoule sealing: For ampoules, use medicinal aluminum foil to seal the neck of the ampoule to ensure sterility and prevent contamination.
Parenteral packaging: For sterile parenteral drugs, specialized laminates containing aluminum foil are used to maintain sterility and protect the drug from external factors.
Cold Forming: Aluminum foil can be used in cold-formed blister packaging, ideal for moisture-sensitive pharmaceuticals that require maximum protection.
Vial sealing: Medication vials are sealed with an aluminum cap, often with a plastic flip-top, to prevent tampering and contamination.
