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, sicurezza, and shelf life. Henan Huawei Aluminium Co., Ltd., 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.

Tavolo 2: Formability Comparison

Formability Indicator Huawei 8021-O Cold-Formed Foil Ordinary 8011-O 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 Tipicamente 5.0 – 6.5mm Prevents rupture due to localized thinning in deep-cavity forming, eliminating leakage risks.
Forming Uniformity​ Molto alto, uniform wall thickness distribution Moderare, 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.

Tavolo 3: Key Safety & Compliance Data

Test Item Ch.P / YBB Standard Limit Henan Huawei Aluminum Typical Control Value International Standard Reference
Total Heavy Metals (as Pb)​ ≤ 5.0 μg/g ≤ 1.0 μg/g Ep 3.2.1, USP <661>
Fluorescent Substances​ Must not be detected Not detected YBB 0017-2005
Extractables Test​ Must comply Fully compliant, with lower typical values Ch.P, USP <87><88>
Microbial Limits​ ≤ 100 cfu/g ≤ 50 cfu/g (produced in cleanrooms) Ep 5.1.4
Volatiles​ ≤ 5.0 mg/m² ≤ 2.0 mg/m² YBB 0004-2003
Certification Support​ Drug Packaging Material Registration Certificate (Type I) Comprehensive Iso 15378, Iso 9001

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.

Tavolo 4: Barrier Performance Comparison & Valore

Barrier Type Test Method Huawei Foil (Coated) Typical Value Ordinary Foil (Spoglio) 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.
Barriera di ossigeno​ ASTM D3985 < 0.5 cm³/(m²·24h·atm) Reduced barrier due to pinholes Prevents oxidation and inactivation of active ingredients in oxidizable drugs (per esempio., vitamins, antibiotics).
Barriera leggera​ Visible/UV Light 100% a prova di luce 100% a prova di luce (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 (per esempio., 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, durevole, and abrasion-resistant graphics.
