Pharmaceutical aluminum foil blister packaging material

In the modern pharmaceutical packaging industry, blister packaging has become one of the primary packaging forms for oral solid dosage forms and health supplements, owing to its excellent barrier properties, user convenience, and effective brand presentation. As the core material in blister packaging that directly protects the medication, the performance of medicinal aluminum foil is critical to the drug’s stability, անվտանգություն, and shelf life. Henan Huawei Aluminium Co., ՍՊԸ, with its deep industry expertise, offers a premium range of medicinal aluminum foils that exceed industry standards, providing reliable solutions for global pharmaceutical companies. This article provides an in-depth analysis from the perspectives of material science, regulatory compliance, and practical application.

II. Four Core Advantages That Exceed Standards

Compared to ordinary medicinal aluminum foil, Henan Huawei Aluminum’s premium products achieve systematic enhancement across four key dimensions.

1. Excellent Deep-Draw Formability and Shape Retention

For complex dosage forms like shaped tablets and large capsules, the foil must withstand significant stretching without failure. Our specially annealed alloys, such as 8021-O, demonstrate exceptional deep-drawing capabilities.

Սեղան 2: Formability Comparison

Formability Indicator Հուավե 8021-Օ Cold-Formed Foil Ordinary 8011-Օ Medicinal Foil Value to Packaging
Limiting Drawing Ratio (LDR)​ ≥ 2.2 Approx. 1.8 – 2.0 Enables deeper, more complex blister shapes, accommodating more dosage forms.
Rupture Depth​ ≥ 8.0mm Որպես կանոն 5.0 – 6.5մմ Prevents rupture due to localized thinning in deep-cavity forming, eliminating leakage risks.
Forming Uniformity​ Շատ բարձր, uniform wall thickness distribution Չափավոր, noticeable thinning at corners Creates smooth, aesthetically pleasing blisters with consistent protection, enhancing product premium feel.
Springback Effect​ Very low Relatively noticeable Stable blister shape after forming, snug fit with product, prevents product movement and abrasion within the blister.

2. Top-Tier Safety Compliance and Cleanliness

The safety of pharmaceutical packaging materials is non-negotiable. Our company implements GMP-concept management throughout the entire process, from raw material intake to finished product dispatch.

Սեղան 3: Key Safety & Compliance Data

3. Outstanding Barrier Protection Properties

While aluminum foil itself provides an excellent barrier, our precision coating process seals pinholes and provides a chemically inert protective interface.

Սեղան 4: Barrier Performance Comparison & Արժեք

Barrier Type Test Method Huawei Foil (Coated) Typical Value Ordinary Foil (Մերկ) Typical Risk Protective Value for Drugs
Water Vapor Barrier​ ASTM F1249 < 0.3 g/(m²·24h) Reduced barrier due to pinholes Prevents drug moisture absorption, degradation, efficacy loss, or toxic byproduct formation.
Թթվածնի պատնեշ​ ASTM D3985 < 0.5 cm³/(m²·24h·atm) Reduced barrier due to pinholes Prevents oxidation and inactivation of active ingredients in oxidizable drugs (օր., vitamins, antibiotics).
Լույսի արգելք​ Visible/UV Light 100% լուսակայուն 100% լուսակայուն (based on Al layer) Protects light-sensitive drugs from photolytic degradation.
Microbial Barrier​ Physical Barrier Complete barrier Complete barrier (based on integrity) Ensures hygienic safety of the drug throughout its shelf life.

4. Superior Processing Adaptability and Production Efficiency

Optimized for high-speed blister packaging machines (speeds exceeding 1000 blisters/minute), our foil excels in the following aspects:

  • Excellent Coefficient of Friction (COF): Controlled between 0.15-0.25, ensuring stable web handling without jamming or slippage.
  • Wide and Stable Heat Seal Window: Broad heat-seal temperature range (օր., 120-160°C) with high seal strength, tolerates equipment temperature fluctuations, ensuring strong, leak-free seals.
  • Superb Printability: Optimized surface treatment ensures strong ink adhesion, resulting in clear, դիմացկուն, and abrasion-resistant graphics.
