Pharmaceutical Aluminium Blister Foil for Pill Packaging
Pharmaceutical Aluminium Blister Foil for Pill Packaging is a widely used packaging material in the pharmaceutical industry, designed specifically for the packaging of pills, capsules, and other oral solid medications. It provides excellent protective properties, ensuring the stability of the medication's quality during transportation, storage, and use, protecting the drug from external environmental factors.
Pharmaceutical aluminium blister foil is used for pill packaging, offering excellent protection for the drugs and ensuring their quality is unaffected during transportation and storage. It effectively prevents moisture, light, gases, and other external factors from impacting the pills, making it an ideal material for pharmaceutical packaging.
Pharmaceutical Aluminium Blister Foil Features
Moisture Resistance
Aluminium blister foil effectively isolates external moisture, preventing the medication from becoming damp. Moisture can lead to the degradation or loss of efficacy of drugs, and the sealing properties of the foil ensure that the drugs remain dry for long periods, especially for medications that require strict drying conditions.
Light Resistance
This material has excellent UV resistance, preventing light from affecting the medication. Light exposure can cause drug degradation, especially for sensitive drugs like vitamins and certain biologics. Therefore, aluminium blister foil effectively protects the drugs from light damage, ensuring their efficacy and stability.
Gas Barrier
Aluminium blister foil can effectively block the entry of gases such as oxygen and nitrogen, preventing oxidation or other chemical reactions with the drug. This gas barrier ensures that the medication retains its chemical properties, avoiding reactions with moisture, oxygen, or harmful gases in the air.
High-Temperature and Low-Temperature Resistance
Pharmaceutical aluminium blister foil has strong temperature resistance and maintains stability in various temperature environments. Therefore, it is suitable for different transportation and storage conditions, particularly when temperature fluctuations are significant, while still providing protection to the drugs.
Mechanical Strength
The strength of aluminium blister foil is high, making it resistant to tearing and ensuring that it remains intact during transportation and usage. This high strength also gives it excellent compressive resistance, helping prevent damage to the medication inside the package.
Ease of Forming and Sealing
Due to its good formability and sealing properties, aluminium blister foil can easily be combined with plastic or other synthetic materials to create a secure package structure, ensuring that each pill is completely sealed, preventing leakage or external contamination.
Pharmaceutical Aluminium Foil
In pharmaceutical blister packaging, commonly used aluminium alloys are Aluminium Alloy 8011 and Aluminium Alloy 8021. These alloys have excellent formability, superior moisture resistance, and corrosion resistance, making them ideal for pharmaceutical packaging, particularly for packaging drugs, capsules, and tablets.
Common Alloys and Features
8011 Aluminium Alloy
Features: 8011 aluminium alloy is one of the most commonly used alloys for blister packaging. It has excellent formability, corrosion resistance, and moisture resistance, and can be processed into thin films through deep processing.
Applications: Suitable for pharmaceutical blister packaging, food packaging, and other fields. Its smooth surface is ideal for printing and provides strong sealing protection.
8021 Aluminium Alloy
Features: 8021 aluminium alloy has excellent toughness and strength, with superior corrosion resistance, making it particularly suitable for high-demand pharmaceutical packaging. It is more durable than 8011 aluminium alloy and is ideal for specific pharmaceutical packaging requirements.
Applications: Commonly used in high-end pharmaceutical packaging, especially in situations requiring superior sealing and permeability resistance.
Other Aluminium Alloys
8079 Aluminium Alloy: Sometimes used for pharmaceutical packaging, particularly for applications requiring additional tensile strength.
1235 Aluminium Alloy: Though less commonly used for blister packaging, it can be used for certain special applications.
8011 and 8021 are the most common choices, as they offer multiple properties suited for pharmaceutical packaging.
Composition of Pharmaceutical Aluminium Blister Foil
Aluminium Foil Layer: Provides the primary protective function, including moisture resistance, light blocking, and gas isolation.
Plastic Layer: Combined with the aluminium foil layer, typically made from materials such as PVC, PET, or other plastics, providing structural support and sealing properties.
Main Applications of Pharmaceutical Aluminium Blister Foil in Pill Packaging
Protection
Pharmaceutical aluminium blister foil effectively prevents the degradation and loss of efficacy of drugs during transportation and storage. It offers several essential protective functions for pills:
Moisture Protection: Moisture can cause drugs to deteriorate or lose potency. Aluminium blister foil blocks moisture, ensuring the stability of the pills.
Light Protection: Some drugs (such as vitamins and hormones) are sensitive to light. The light-blocking properties of aluminium foil protect the drugs from UV and visible light degradation.
Oxidation Prevention: Oxygen can react with drug components, causing oxidation. Aluminium blister foil effectively isolates oxygen, reducing the risk of oxidation.
Gas Contamination Prevention: Aluminium blister foil effectively blocks harmful gases (such as nitrogen and carbon dioxide) from entering, maintaining the chemical stability of the drugs.
Individual Packaging
Pharmaceutical aluminium blister foil provides individual packaging for each pill, typically through heat sealing, securing each medication in a blister. Each blister can be designed as needed, ensuring accurate dosage and preventing external contamination.
Single-Dose Packaging: Each pill is individually packaged, preventing contamination from exposure to air or other medications.
Convenience: Users can easily tear open the blister to access the medication, ensuring accurate dosing and preventing incorrect consumption.
Packaging Labeling and Consumer Convenience
Aluminium blister foil not only provides protection but also enhances consumer experience:
Transparent Plastic Backing: The plastic layer of the blister is usually transparent, allowing consumers to clearly see the appearance and quantity of the pills, avoiding misuse.
Easy-to-Tear Design: The design of aluminium blister foil is usually easy to tear, making medication usage more convenient and efficient.
Labeling and Marking: The surface of the aluminium foil can be printed with information such as the drug's name, dosage, production date, expiration date, and manufacturer, providing consumers with essential information.
Extending Shelf Life
By effectively isolating external environments, aluminium blister foil significantly extends the shelf life of medications. Compared to traditional bottle or paper packaging, aluminium blister foil better preserves the freshness and efficacy of drugs, especially those sensitive to environmental changes.
Reducing Production Costs and Improving Packaging Efficiency
Aluminium blister foil has high processing efficiency, reducing material waste and increasing precision and automation in the production process. It can typically be produced through modern automated packaging machinery, lowering labor costs and improving production speed.
Advantages of Pharmaceutical Aluminium Blister Foil
- Enhances drug stability: Effectively protects drugs from external environmental influences, extending their shelf life.
- Improves user experience: Through the transparent plastic backing, consumers can easily see the drug's form, color, and quantity for better usage.
- Convenient dose management: Each drug unit is individually packaged, ensuring precise dosage control and preventing misuse or overuse.
Pharmaceutical aluminium blister foil, with its superior protective properties and adaptability, has become an indispensable packaging solution in the pharmaceutical industry, ensuring drug quality and enhancing the market competitiveness of medications.
