Cold Forming Alu Alu Bottom Foil for Pharmaceutical Packaging

Cold forming aluminum bottom foil is a widely used packaging material in the pharmaceutical industry, often used as part of the aluminum-aluminum blister packaging (Alu-Alu), in conjunction with the top aluminum foil. Its main function is to provide an effective physical barrier for medicines, protecting them from external factors such as air, moisture, and light, ensuring the stability and safety of the medicines.

Cold Forming Alu Alu Bottom Foil Structure and Composition

Bottom Aluminum Foil (Alu Bottom Foil): This layer of aluminum foil typically has high mechanical strength, serving as the base for packaging medicines, bearing pressure during the cold forming process and external environmental influences. It provides the basic sealing performance and ensures the safety of the medicine.
Top Aluminum Foil: This layer of aluminum foil is placed above the bottom foil and often forms a tight sealing structure with the bottom foil, ensuring that the medicine is fully sealed inside, unaffected by external factors.

Cold Forming Alu Alu Bottom Foil Cold Forming Process

Cold forming aluminum bottom foil adopts a specialized cold forming technique, allowing the aluminum foil to be shaped and sealed without heating. Compared to conventional heat-formed aluminum foil, cold forming aluminum bottom foil has the following advantages:

Excellent Ductility and Strength: Even under high pressure, the aluminum bottom foil maintains its structural integrity without cracking or deforming.
Sealing Performance: Cold forming aluminum foil has strong sealing properties, forming a highly tight structure that prevents external factors such as air, moisture, and light from affecting the quality of the medicine.
Improved Packaging Precision: Since the cold forming process allows precise control over the shape, medicines can be packaged accurately, reducing losses or damage caused by improper packaging.

Cold Forming Alu Alu Bottom Foil Applications

Biologics: These medicines often require strict environmental control to prevent moisture, air, or light from affecting their efficacy. Cold forming aluminum bottom foil effectively mitigates these risks.
High-Value Drugs: Such as vaccines, hormones, antibiotics, etc., these medicines typically require special packaging to ensure their stability and effectiveness.
General Medicines: Including tablets, capsules, granules, etc., cold forming aluminum bottom foil is also widely used in their packaging, ensuring the quality is maintained during long-term storage and transportation.

Cold Forming Alu Alu Bottom Foil Advantages

High Barrier Performance: Cold forming aluminum bottom foil has excellent air, moisture, and light barrier properties, effectively isolating harmful factors such as moisture, oxygen, and ultraviolet light.
Extended Shelf Life: Due to its excellent physical barrier properties, cold forming aluminum bottom foil significantly extends the shelf life of medicines, especially those that need to be stored for long periods.
Safety and Reliability: The aluminum foil does not contain harmful substances, complies with stringent pharmaceutical packaging standards, ensuring the safety of the medicine packaging and reducing contamination risks.
High Strength and Flexibility: Cold forming aluminum bottom foil can withstand various external forces that may occur during production, transportation, and use without affecting its packaging function.

Common Pharmaceutical Packaging Types for Cold Forming Alu Alu Bottom Foil

Aluminum-Aluminum Composite Packaging (Alu-Alu): Cold forming aluminum bottom foil, together with another layer of aluminum foil (top foil), forms a completely aluminum-sealed packaging, widely used for drugs sensitive to moisture, oxygen, and light.
Aluminum-Plastic Packaging (Alu-PVC): Cold forming aluminum bottom foil serves as the bottom material, combined with PVC or other polymer materials, forming a standard packaging form suitable for most medicines.

Cold Forming Alu Alu Bottom Foil Quality Standards and Certifications

Cold forming aluminum bottom foil needs to meet international pharmaceutical packaging standards and certification requirements, such as:

FDA Certification: Ensures the aluminum foil meets the U.S. Food and Drug Administration requirements for pharmaceutical packaging.
ISO Certification: Ensures the aluminum foil meets international quality management standards during the production process.
GMP Certification: Complies with Good Manufacturing Practices to ensure strict management of the production process and the quality and safety of the pharmaceutical packaging.

Cold forming aluminum bottom foil is an indispensable material in pharmaceutical packaging, especially suitable for medicines that require high sealing and long-term preservation. Its strength, ductility, and high barrier properties make it an ideal packaging solution for medicines sensitive to moisture, oxygen, and light (such as biologics and vaccines). Through cold forming technology, this aluminum foil provides a reliable physical barrier, ensuring the quality and effectiveness of medicines and maintaining their safety and stability throughout the entire supply chain.
