Tropical Blister Foil
Tropical aluminum blisters serve as protective covers for conventional PVC hard film thermoformed blister packaging, without direct contact with medications or food, making them suitable for high-density pharmaceutical packaging.
Tropical aluminum blisters possess excellent properties such as light protection, moisture resistance, oxidation resistance, and gas barrier capabilities. They are commonly available in silver and gold colors, and the surface can be beautifully printed for promotional effects.
- Uses: Used for aluminum-plastic blister packaging for capsules, tablets, and more.
- Structural Specifications: OPA 25um/AL 60um/DVC
Tropical pharmaceutical aluminum foil, also known as aluminum-plastic-aluminum packaging, typically consists of thermoformed plastic blisters combined with PTP aluminum foil, topped with a layer of cold-pressed aluminum foil. Common aluminum foil types include 8021-O and 8079-O, suitable for high-end pharmaceutical packaging.
| Characteristics | Description |
| Enhanced protective performance | Tropical blister foil provides an impermeable barrier that effectively protects the most sensitive products, suitable for various medications, and extends shelf life. |
| Typical structure | Composed of two layers, usually OPA/AL/VC (nylon, aluminum, and adhesive), laminated under certain temperature and pressure conditions. |
| Moisture-proof and barrier capability | Compared to traditional aluminum-plastic packaging, tropical blister aluminum foil is enhanced with an aluminum-plastic composite film on the back of the PVC blister, improving light-blocking and moisture-proof performance. |
Role of Nylon
The primary role of nylon in blister packaging is to support the aluminum layer, ensuring that the nylon and aluminum layer do not delaminate or break during the stamping process, thereby maintaining the integrity of the packaging.
Tropical aluminum packaging is not a replacement for cold-formed aluminum, but rather a diversified packaging solution based on the moisture protection requirements and display effects of different medications. Its moisture-proof effect relies on the thermal sealing effect of the edges and PVC blisters, where the stability of the temperature during the sealing process, the smoothness of the mold surface, and the uniformity of the pressure all affect the sealing results. Therefore, the coating of tropical aluminum is particularly important for ensuring packaging performance.

What is tropical blister used for?
Aluminum tropical blister foil is primarily used to cover PVC blister packaging and is widely applied to protect various pharmaceuticals, such as capsules, tablets, powders, liquids, and suppositories. This packaging form provides multiple protections, ensuring the safety and effectiveness of medications during storage and transportation.
1. Light Protection
Light-blocking protection: Aluminum tropical blister foil effectively blocks UV and visible light, preventing light from degrading the active ingredients of medications. Many drugs are sensitive to light, and prolonged exposure can reduce their efficacy, making the light-blocking characteristics of aluminum foil crucial.
Extending shelf life: By blocking light, aluminum foil helps prolong the shelf life of medications, ensuring their stability and activity within the effective period.
2. Moisture Protection
High moisture barrier: Aluminum tropical blister foil offers excellent water vapor barrier properties, preventing moisture from penetrating the packaging, thus protecting medications from humid environments. Humidity can lead to degradation or ineffectiveness of drugs, making good moisture-proof performance very important.
Suitable for high-humidity environments: This packaging can maintain the quality of medications under high humidity conditions, making it suitable for various environments, especially in humid climates.
3. Oxygen Protection
Preventing oxygen permeation: The structural design of aluminum tropical blister foil effectively prevents the entry of oxygen, reducing the risk of oxidation of the medications. Oxygen can lead to chemical changes in drug components, affecting their effectiveness and safety.
Retaining efficacy: By blocking oxygen, aluminum foil helps retain the active ingredients of medications, ensuring patients receive the expected therapeutic effects.
4. Wide Applicability
Compatibility with various dosage forms: Aluminum tropical blister foil is suitable for various pharmaceutical dosage forms, including capsules, tablets, powders, liquids, and suppositories. Its flexibility allows this packaging form to meet the needs of different medications.
