Pharmaceutical packaging often utilizes aluminum foil due to its advantageous properties. Here are some key properties of 20 micrometer thick aluminum foil commonly used in pharmaceutical packaging:

1. **Barrier Properties**: Aluminum foil provides excellent barrier properties against moisture, light, gases, and contaminants. 20micron aluminum foil helps to protect pharmaceutical products from degradation and ensures their stability over time.

2. **Lightweight and Flexible**: Aluminum foil is lightweight and flexible, making it easy to handle and manipulate during packaging processes. Its flexibility allows for easy sealing and forming around pharmaceutical products.

3. **Heat Resistance**: Aluminum foil exhibits high heat resistance, which is essential for sterilization processes commonly used in pharmaceutical manufacturing. It can withstand high temperatures without deforming or compromising its barrier properties.

4. **Corrosion Resistance**: Aluminum foil is resistant to corrosion, ensuring that pharmaceutical products remain protected and uncontaminated throughout their shelf life.

5. **Printability**: Aluminum foil can be easily printed with product information, branding, and safety warnings using various printing techniques. This allows for clear labeling and identification of pharmaceutical products.

6. **Tear Resistance**: Despite its thinness, aluminum foil has good tear resistance, which prevents accidental tearing or puncturing during handling and transportation.

7. **Recyclability**: Aluminum foil is recyclable, making it an environmentally friendly choice for pharmaceutical packaging. Recycling aluminum foil helps to reduce waste and conserve natural resources.

Overall, the combination of barrier properties, flexibility, heat resistance, and recyclability makes 20 micrometer thick aluminum foil an ideal choice for pharmaceutical packaging, ensuring the integrity and safety of pharmaceutical products throughout their lifecycle.
