Aluminum Tearing Blister Foil

What is Aluminum Tearing Blister Foil?

Aluminum tearing blister foil is a specialized packaging material designed primarily for the pharmaceutical and healthcare industries. It consists of thin aluminum sheets engineered for high barrier properties, durability, and ease of tearing. This material is crucial for protecting sensitive products such as tablets, capsules, and other pharmaceuticals from environmental factors like moisture, oxygen, and light. Typical alloys used for its production include 8011, 8021, and 8079, which are known for their excellent strength and corrosion resistance. The material’s thickness usually ranges between 20 µm to 50 µm, ensuring a balance between functionality and cost-effectiveness.

Common feathers of aluminum tearing blister foil

Aluminum tearing blister foil requires alloys with good strength, ductility, and corrosion resistance to meet the demands of tearing, sealing, and protecting pharmaceutical products. Below are the commonly used alloys and their characteristics:

Common Aluminum Alloys

1. 8011 Alloy
   • Characteristics: The most widely used aluminum foil alloy with excellent corrosion resistance, formability, and sealing properties.
   • Applications: Commonly used in pharmaceutical and food packaging.
   • Temper: H18 (hard temper) or O (soft temper).
2. 8021 Alloy
   • Characteristics: Offers higher ductility and puncture resistance, suitable for applications requiring high barrier properties.
   • Applications: Used for high-end pharmaceutical blister packaging, especially for products requiring excellent protection against moisture and oxygen.
   • Temper: O temper.
3. 8079 Alloy
   • Characteristics: Known for its excellent corrosion resistance and ductility, ideal for ultra-thin aluminum foil processing.
   • Applications: Suitable for blister packaging with high sealing requirements for pharmaceuticals or food.
   • Temper: O temper.

Temper Explanations

• H18: Hard aluminum foil with high strength but relatively lower ductility, suitable for packaging with high tearing requirements.
• O (Annealed): Soft aluminum foil with good ductility, suitable for processing into complex shapes.

Typical Thickness Range

• Thickness: 0.02 mm – 0.05 mm (20 µm – 50 µm)
• Width: Customized according to customer requirements.

Additional Considerations

• Coatings on blister aluminum foil (e.g., adhesive and printing coatings) are crucial to ensure compatibility with heat sealing and printing needs.
• Aluminum foil used for pharmaceutical packaging must comply with FDA or EU food-grade safety standards.
