Alu alu blister foil
What is an Alu Alu Blister?
Alu Alu blister foil is a high-barrier cold-form foil used for pharmaceutical packaging, providing enhanced protection for sensitive products such as tablets, capsules, and other solid dosage forms. Its advanced structure offers exceptional moisture, oxygen, and light protection, maintaining product stability and extending shelf life.
Composition of Alu Alu Blister Foil
- Layer Structure: Typically composed of two layers of aluminum foil (alu alu), which block moisture, light, and oxygen.
- Thickness: Common thickness range for each layer is 20µm to 50µm, depending on specific applications and requirements.
Physical Properties of Alu Alu Blister Foil
- Tensile Strength: High tensile strength to withstand stress during packaging and handling.
- Sealing Temperature: Requires specific temperature settings for effective sealing, typically around 130°C to 180°C.
- Oxygen and Moisture Barrier: Excellent barrier properties to prevent moisture and oxygen ingress, extending product shelf life.
Chemical Properties of Alu Alu Blister Foil
- Compatibility: Chemically inert, suitable for various pharmaceuticals and food products.
- Resilience: Resistant to a variety of substances, including acids and bases.
Performance Characteristics of Alu Alu Blister Foil
- Formability: Easily shaped into various forms, suitable for different types of products.
- Seal Integrity: Provides a strong seal, minimizing the risk of contamination and product degradation.

Advantages of Alu Alu Blister Foil
1. In aluminum-aluminum packaging, the aluminum foil provides excellent protection for pharmaceuticals, shielding them from moisture, oxygen, and UV radiation. These external factors can degrade their quality or efficacy.
2. The robust design of Alu-Alu blister packaging prevents physical damage or impact during handling, transportation, and storage.
3. The superior barrier performance of aluminum-aluminum packaging helps extend the shelf life of pharmaceuticals.
4. Aluminum-aluminum packaging features tamper-evident functionality. For example, perforated or torn labels can provide clear indications of tampering, ensuring the integrity of the internal product.
Limitations of Alu Alu Blister Foil
1. Aluminum-aluminum packaging, due to its aluminum-based materials, is typically more expensive than other packaging solutions, leading to increased production costs.
2. Although aluminum foil itself is recyclable, the blister packaging is not made from this single material. Additionally, aluminum foil is not biodegradable, thus having an environmental impact to some extent.
3. The use of aluminum-based materials in packaging makes it difficult to visually inspect the contents of each blister cavity without opening the package.
4. Aluminum foil is not as flexible as plastic and cannot be easily shaped into any form.
Alu Alu Cold Forming Foil
Alu alu cold forming foil is a special aluminum foil used in blister packaging production, specifically designed to form seals that protect sensitive products (such as pharmaceuticals) from environmental factors.
Alu alu cold forming foil is specifically designed for cold-formed blisters. It is not heat-formed; instead, it is shaped under pressure, making it an ideal choice for sensitive medications. The aluminum foil provides robust protection without the need for high temperatures, making it particularly suitable for temperature-sensitive drugs.
Features:
- Cold Forming Process: Unlike traditional blister packaging that typically uses PVC or PET, cold forming foil is entirely made of aluminum, allowing for deeper and more complex shapes.
- No Plastic Layer: This foil does not require a plastic layer, enhancing its barrier performance.
- Outstanding Barrier Performance: Provides comprehensive protection against all environmental factors.
- Non-Reactive: Safe for direct contact with pharmaceuticals.
- Design Versatility: Customizable according to different blister designs and cavity depths.
Applications:
Mainly used for packaging solid dosage pharmaceuticals (tablets, capsules) that are sensitive to moisture and oxygen.
HC Aluminum Blister Packaging
HC Aluminum's aluminum blister packaging is widely used for pharmaceuticals, food, and consumer products. It provides a protective barrier to extend the product's shelf life.
Components:
Blister: Pre-formed cavities made from aluminum foil, typically used to hold products.
Seal Foil: A layer that seals the blister, providing an airtight and moisture barrier.
Advantages:
- Tamper-Evident: Aluminum foil offers visible tamper-proof features.
- Product Protection: Protects products from environmental factors such as light, moisture, and oxygen.
- Convenience: Easy to use and provides portion control for consumers.
