Cold Form Foil(60 µm PVC/ 25 µm OPA/ 45 µm Alu foil/ 6-8 GSM Universal HSL)
Cold Form Foil (60 µm PVC/ 25 µm OPA/ 45 µm Alu foil/ 6-8 GSM Universal HSL) is a high-performance composite packaging material, consisting of a 60-micron PVC layer, a 25-micron OPA layer, and a 45-micron aluminum foil, with a 6-8 grams per square meter universal heat seal coating. This design gives the material excellent moisture resistance, oxygen barrier, and light protection, making it ideal for pharmaceutical and health product packaging. It effectively extends the product's shelf life and maintains its stability.
Cold Form Foil is a high-performance composite packaging material designed for pharmaceuticals, health products, and other sensitive products that require high barrier properties. Its unique multi-layer structure and excellent barrier performance make it one of the most widely used packaging materials in the pharmaceutical industry.
Cold Form Foil 60 µm PVC 25 µm OPA 45 µm Alu foil 6-8 GSM HSL Material Structure
| Layer | Material | Thickness | Function and Features |
| Outer Layer | PVC (Polyvinyl Chloride) | 60 µm | Provides mechanical strength, chemical resistance, and puncture resistance, with good transparency and appearance. |
| Middle Layer | OPA (Nylon/Polyamide) | 25 µm | Enhances tear resistance and elasticity, improves mechanical strength and impact resistance, and is adaptable to complex forming processes. |
| Barrier Layer | Alu Foil (Aluminum Foil) | 45 µm | 8011, 8021, 8079 aluminum foils are primarily used as barrier layers, offering excellent moisture, oxygen, and light protection, ensuring the stability of the contents. |
| Inner Layer | Universal HSL (Heat Seal Coating) | 6-8 GSM | Provides efficient heat sealing performance, ensuring a strong bond with substrates such as PVC, PVDC, etc., enhancing package integrity. |
