Cold Form Foil (25 µm OPA/ 50 µm Alu foil/ 60 µm PVC)
Cold Form Foil (25 µm OPA/ 50 µm Alu foil/ 60 µm PVC) is a composite packaging material with excellent barrier properties, consisting of a 25-micron OPA layer, a 50-micron aluminum foil layer, and a 60-micron PVC layer. The increased thickness of the aluminum foil further enhances its moisture and oxygen barrier performance, making it ideal for packaging high-end pharmaceuticals and special nutritional products, ensuring their safety during transportation and storage.
Cold Form Foil is a commonly used composite material in pharmaceutical packaging, particularly in single-dose drug packaging, such as blister packs. It is typically made of multiple layers of different materials, each serving a specific function.
| Material | Thickness | Function |
| OPA Layer | 25 µm | Provides excellent airtightness, protecting the drug from external moisture, ensuring the drug remains dry and extends its shelf life. |
| Aluminum Foil Layer | 50 µm | Enhances the protective properties, particularly in shielding against light, oxygen, and moisture, maintaining the long-term stability and potency of the drug. |
| PVC Layer | 60 µm | Provides good mechanical strength and durability, ensuring the stability and damage resistance of the packaging material, suitable for transportation and storage. |
Cold Form Foil 25 µm OPA 50 µm Alu foil 60 µm PVC Structure and Function
Cold Form Foil (25 µm OPA/ 50 µm Alu foil/ 60 µm PVC) is a multi-layer composite packaging material widely used in pharmaceutical packaging, especially for single-dose drugs and special nutritional products. Each layer of the material has a unique function, working together to provide excellent protective performance, ensuring the drug maintains its potency and safety during transportation and storage.
OPA Layer (25 µm)
- Thickness: 25 microns
- Function: The OPA (Oriented Polyamide) layer is mainly used to provide excellent airtightness, ensuring that the drug is protected from moisture. It has strong gas barrier properties, effectively preventing the infiltration of water vapor and oxygen from the external environment, reducing the risk of the drug becoming moist, deteriorating, or oxidizing.
- Application: This layer is typically used in packaging where the drug needs to remain dry, especially in humid environments.
Aluminum Foil Layer (50 µm)
- Thickness: 50 microns
- Function: The aluminum foil layer is one of the most important parts of Cold Form Foil, with excellent protective properties. It provides a strong shield against oxygen, light, and moisture, effectively extending the shelf life of the drug. The increased thickness of the aluminum foil significantly improves its barrier performance, particularly in cases where high protection for drugs is required, such as for high-end pharmaceuticals and nutritional products.
- Application: Commonly used in packaging that requires strong barrier performance, such as for long-term drug storage and for high-value products sensitive to environmental conditions.
PVC Layer (60 µm)
- Thickness: 60 microns
- Function: The PVC layer provides good mechanical strength and durability, ensuring the stability and resistance to damage of the packaging material. PVC is a tough material that can withstand physical pressure during transportation and storage, while also helping to maintain the integrity of the entire packaging structure.
- Application: This layer enhances the overall stability of the packaging, especially for applications requiring abrasion resistance and impact resistance.
