Cold Form Foil (25 µm OPA/ 45 µm Alu foil/ 60 µm PVC)
Cold Form Foil (25 µm OPA/ 45 µm Alu foil/ 60 µm PVC) is a high-performance packaging material that combines a 25-micron OPA layer, a 45-micron aluminum foil, and a 60-micron PVC layer, offering excellent barrier properties and mechanical strength. This composite material is ideal for packaging pharmaceuticals and dietary supplements, effectively preventing the ingress of moisture, light, and oxygen, thereby ensuring the stability and efficacy of the product.
Cold Form Foil is a commonly used composite material in pharmaceutical packaging, particularly for single-dose drug packaging, such as blister packs. It typically consists of multiple layers of different materials, each serving a specific function.
| Material Layer | Function Description | Thickness |
| OPA (25 µm) | Provides excellent gas tightness and moisture barrier capabilities, effectively protecting the drug from external environmental influences. | 25 µm |
| Aluminum Foil (45 µm) | Provides excellent shielding performance, preventing light, oxygen, and moisture from affecting the stability of the drug. | 45 µm |
| PVC (60 µm) | Provides mechanical strength and durability, protecting the packaging structure. | 60 µm |
Cold Form Foil 25 µm OPA 45 µm Alu foil 60 µm PVC Structure
Cold Form Foil (25 µm OPA/ 45 µm Alu foil/ 60 µm PVC) is a multilayer composite material widely used in the packaging of pharmaceuticals and dietary supplements, especially suitable for single-dose drug packaging (such as blister packs). It consists of three different material layers, each providing unique performance advantages, making it an efficient packaging solution.
OPA Layer (25 µm)
- Function: The OPA (Oriented Polyamide) layer primarily provides excellent gas tightness and moisture barrier capabilities. It effectively prevents the penetration of moisture and gases, protecting the drug inside the packaging from external environmental influences. It is especially suitable for maintaining the stability of pharmaceuticals by preventing moisture and gas ingress.
- Thickness: 25 microns.
- Features: The OPA layer has high mechanical strength and excellent tear resistance, ensuring that the packaging does not easily break during transportation and use. Its oriented molecular structure also enhances its resistance to penetration and gas barrier properties.
Aluminum Foil Layer (45 µm)
- Function: The aluminum foil layer is the key component of Cold Form Foil, primarily providing excellent shielding performance. It effectively prevents light, oxygen, and moisture from affecting the drug, thereby extending its shelf life and maintaining its efficacy. Aluminum foil blocks UV light, oxygen, and water vapor from entering, ensuring that the drug is not affected by external adverse environmental factors during storage and transportation.
- Thickness: 45 microns.
- Features: Aluminum foil has excellent barrier properties and stability, maintaining long-term structural integrity to protect the drug from external factors. Its thickness selection effectively balances cost and protective performance, making it suitable for long-term packaging needs.
PVC Layer (60 µm)
- Function: The PVC (Polyvinyl Chloride) layer provides the necessary mechanical strength and durability, making the entire packaging structure more stable. It protects the other inner layers from external damage and provides the necessary hardness during packaging, preventing the packaging from being crushed or damaged during transport. The PVC layer also helps ensure the integrity of the packaging, providing adequate support.
- Thickness: 60 microns.
- Features: PVC has good processability and heat sealability, making it an ideal outer layer material. Its higher thickness also makes the packaging more robust and durable, effectively protecting the drug from mechanical impact.
Cold Form Foil 25 µm OPA 45 µm Alu foil 60 µm PVC Comprehensive Performance
Cold Form Foil combines the advantages of three layers of materials: the gas tightness and moisture barrier properties of OPA, the shielding performance of aluminum foil, and the mechanical strength and durability of PVC. This makes Cold Form Foil an ideal packaging material, effectively preventing external factors (such as oxygen, moisture, and light) from affecting the drug, ensuring its stability and efficacy. It is widely used in the pharmaceutical industry, especially for drugs and dietary supplements that require single-dose packaging and long-term stability protection.
Cold Form Foil 25 µm OPA 45 µm Alu foil 60 µm PVC Applications
- Pharmaceutical Packaging: Especially suitable for single-dose drug packaging, such as blister packs, effectively protecting the drug from external influences and maintaining its quality and efficacy.
- Nutritional Supplement Packaging: For nutritional supplements, Cold Form Foil provides the necessary protection to ensure product stability throughout its shelf life.
- Other High-Demand Packaging: It can also be used for high-end packaging in industries that require moisture, light, and oxidation protection, such as cosmetics and food.
Cold Form Foil, with its highly integrated three-layer structure, provides comprehensive protection and functionality, ensuring its advantages in various packaging applications.
