【Comprehensive Analysis of Cold Aluminum Blister Packaging】

In pharmaceutical packaging, blister packaging is a common and efficient form, while cold aluminum blister packaging (also known as Alu-Alu packaging) has become the preferred solution for high-end pharmaceutical packaging due to its excellent barrier properties and mechanical strength. This article will give you a comprehensive understanding of the characteristics and advantages of cold aluminum blister packaging.

1. What is cold aluminum blister packaging?

Cold aluminum blister packaging refers to a packaging form composed of three layers of composite materials (OPA/AL/PVC), with opaque aluminum materials on the top and bottom. Its core lies in "cold forming" - mechanical extrusion and shaping through molds without the need for thermal heating.

2. Structural composition of cold aluminum blister packaging

1. OPA (nylon): Improve molding ductility and puncture resistance;

2. AL (aluminum foil): Provides extreme oxygen barrier, moisture barrier and light shielding protection;

3. PVC (hard film): Enhances structural stability and sealing after molding.

3. Six characteristics of cold aluminum blister packaging

1. **Excellent barrier properties**

Cold aluminum packaging has the industry-leading oxygen barrier, moisture barrier and light-shielding effects, which can protect drugs from environmental influences to a great extent. It is one of the blister packaging forms with the strongest comprehensive barrier properties.

2. **Completely opaque design**

Because both sides are aluminum layers, it has good light-shielding properties, which prevents light from affecting the drug ingredients and is suitable for light-sensitive drugs.

3. **Cold forming process**

No need for heating and forming, cold pressing through molds, suitable for special structures and deep blister drugs, improving the integrity and aesthetics of packaging seals.

4. **High mechanical strength**

The blister structure after forming is stable, with excellent anti-extrusion and anti-tearing capabilities, and can better cope with shock and pressure during transportation and storage.

5. **Adapt to high-end and export markets**

This type of packaging is often used for high-value-added drugs such as biological agents, antibiotics, hormones, etc., meets the requirements of international pharmacopoeias such as Europe and the United States, and is widely used in global drug export packaging.

6. **Cost and efficiency consideration**

Although its packaging material cost and forming efficiency are slightly higher than aluminum-plastic packaging, its cost performance is still outstanding in scenarios with high requirements for packaging quality and drug protection.

4. Introduction to Jiruier cold-formed aluminum series products

Jirel has been focusing on pharmaceutical packaging materials for 17 years. The cold-formed aluminum series products adopt the international standard OPA+AL+PVC structure, with excellent deep-drawing performance and compatibility. It has served pharmaceutical companies in Southeast Asia, the Middle East, Africa and other regions, and is widely used in the field of exported drugs and high-end preparations.
