Pharma Aluminium Blister Foil for Capsule and Tablet Packaging

Pharma Aluminium Blister Foil is a specialized packaging material used in the pharmaceutical industry, primarily for packaging drugs such as capsules, tablets, etc., to ensure the protection and preservation of the medication. It is typically composed of a layer of aluminum foil combined with other materials such as PVC, PVDC, PET, etc., providing excellent protective properties to prevent external factors like moisture, oxygen, and light from affecting the quality of the drugs.

Pharma Aluminium Blister Foil Composition Materials

1. Aluminum Foil Layer

The aluminum foil layer is one of the core components of pharmaceutical blister packaging, primarily providing strong barrier properties to ensure that the drugs are protected from moisture, oxygen, ultraviolet light, and other environmental factors during transportation and storage, thus maintaining the drug's stability and effectiveness. The excellent barrier properties of aluminum foil can effectively extend the shelf life of the drugs, ensuring their quality throughout the product lifecycle.

The selection of the aluminum foil layer is usually based on the following points:

Strong Barrier Properties: The aluminum foil itself has excellent sealing performance, capable of blocking moisture, oxygen, and UV light, which is crucial for many sensitive drugs (such as antibiotics, vitamins, etc.).

Mechanical Properties: The aluminum foil layer needs to have sufficient mechanical strength to prevent damage during packaging and transportation and to maintain the integrity of the blister packaging.

Common Aluminum Alloys:

In pharmaceutical packaging, the aluminum alloy 8011 is one of the most commonly used alloys for producing aluminum foil layers due to its good processing performance, barrier properties, and cost-effectiveness.

2. Bottom Film Materials (such as PVC, PVDC, PET, etc.)

Bottom film materials primarily provide the structural integrity of the blister packaging, ensuring that the blister can withstand mechanical pressure and keep the drugs secure. In addition, it must have good heat-seal properties with the aluminum foil layer to ensure the packaging's sealability and anti-counterfeiting features.

Common bottom film materials include:

• PVC (Polyvinyl Chloride): PVC is one of the most commonly used blister bottom film materials because of its low cost, good formability, and appropriate mechanical strength. PVC offers good transparency, effectively showcasing the appearance of the drugs, and is often used for packaging capsules and tablets. However, its barrier properties are relatively weak and usually require a combination with the aluminum foil layer.
• PVDC (Polyvinylidene Chloride): PVDC has excellent barrier properties, particularly for oxygen and water vapor. It is commonly used for packaging drugs that are very sensitive to environmental factors, providing additional protection to prevent drug degradation. The chemical resistance of PVDC also makes it crucial for packaging special drugs.
• PET (Polyethylene Terephthalate): PET is a material with good strength, heat resistance, and transparency. It is commonly used for high-end drug packaging and for products where appearance is important. The combination of PET with the aluminum foil layer enhances the overall strength and durability of the packaging.

Below is a comparison table of the three common blister bottom film materials: PVC, PVDC, and PET:

The selection of these bottom film materials is typically determined by factors such as the type of drug, packaging requirements, and production costs. They work in combination with the heat-sealing properties of the aluminum foil layer to ensure the integrity and stability of the drug, while also providing sufficient mechanical strength to the blister packaging.

Pharma Aluminium Blister Foil Functions

• Barrier Properties: The aluminum foil layer effectively prevents the influence of external factors such as oxygen, moisture, and light, ensuring the potency and stability of the drug. This is crucial for many drugs that are sensitive to oxidation or moisture.
• Protection: The high mechanical strength of the aluminum blister foil helps prevent the drugs from being compressed or damaged during transportation and use, ensuring the integrity of the drug.
• Sealing: The blister foil’s excellent heat-seal properties ensure the packaging is tightly sealed, preventing the drug from coming into contact with air or contaminants.

Pharma Aluminium Blister Foil Applications

Pharma Aluminium Blister Foil for Capsule Packaging

Pharma aluminium blister foil for capsule packaging is specifically designed to provide a protective barrier for pharmaceutical capsules. This foil typically consists of a laminate structure, where an aluminum foil layer is bonded with other materials such as PVC or PVDC. The aluminum foil ensures moisture, light, and air resistance, preserving the capsule's stability and potency. It is commonly used for packaging various types of capsules, offering a tamper-evident feature and enhancing shelf life. The material's strength and flexibility allow for precise sealing, ensuring secure and hygienic packaging.

Pharma Aluminium Blister Foil for Tablet Packaging

Pharma aluminium blister foil for tablet packaging is a widely used material for securely enclosing pharmaceutical tablets in individual blisters. This foil provides excellent protection against external factors like moisture, oxygen, and light, which could degrade the efficacy of the tablets. It often consists of a multi-layer structure, with an aluminum foil layer serving as the main barrier, combined with PVC or PVDC layers for sealing and forming the blister pockets. The foil ensures easy handling, tamper-evidence, and optimal protection of the tablets, extending their shelf life while maintaining their quality and effectiveness.

Advantages of Pharma Aluminium Blister Foil

• Excellent Barrier Properties: The aluminum foil layer of the blister foil has strong barrier properties, preventing the penetration of moisture, oxygen, and ultraviolet light, thus preserving the freshness and potency of the drug.
• Protects Drug Stability: It prevents drugs from being affected by environmental changes (such as moisture and oxygen), especially for drugs that are prone to oxidation or are light-sensitive.
• Convenient Single-Dose Packaging: It allows consumers to use the drug as needed, reducing waste and ensuring the correct dosage with each use.
• High Mechanical Strength: The aluminum blister foil has excellent tear resistance, protecting the drug's safety during transportation and use.
• Good Heat-Sealing Properties: It can bond firmly with different materials (such as PVC, PVDC), creating an effective sealed package.

Pharma Aluminium Blister Foil for Capsule and Tablet Packaging is an efficient and reliable pharmaceutical packaging material. Its excellent barrier properties, durability, heat-seal performance, and environmental friendliness make it the ideal choice for global drug packaging. It not only effectively protects the stability and potency of the drugs but also enhances their market competitiveness, ensuring consumer health and safety.
