Cold Form Foil (25 µm OPA/ 47 µm Alu foil/ 60 µm PVC)

Cold Form Foil (25 µm OPA/ 47 µm Alu foil/ 60 µm PVC) is a high-performance packaging material consisting of a 25 µm OPA layer, a 47 µm aluminum foil layer, and a 60 µm PVC layer, offering enhanced barrier properties and greater durability. The design of this material ensures excellent protection for the internal products, especially suitable for packaging drugs sensitive to light and humidity, ensuring that the drugs maintain their optimal condition throughout their shelf life.

Cold Form Foil is a composite material commonly used in pharmaceutical packaging, particularly for single-dose drug packaging such as aluminum blister packs. It is typically composed of multiple layers of different materials, each serving a specific function.

The aluminum foil (Alu foil) used in Cold Form Foil is typically made from pure aluminum or aluminum alloys. Common aluminum alloys include:

• 1050 Aluminum Alloy: This alloy contains 99.5% aluminum, offering good ductility and strong corrosion resistance, making it suitable for packaging applications. Its main advantages are high purity and better barrier properties.
• 8079 Aluminum Alloy: A common alloy used in food and pharmaceutical packaging, with higher strength and better mechanical properties. It performs excellently in terms of oxidation resistance and corrosion resistance, making it a frequently used material for aluminum foil in Cold Form Foil.
• 3003 Aluminum Alloy: A more common aluminum alloy containing a small amount of manganese, which provides good strength and corrosion resistance. While its strength is slightly higher than pure aluminum, it retains good formability, making it suitable for packaging materials.

Depending on the application requirements, the aluminum foil in Cold Form Foil may use one of these alloys to ensure excellent barrier properties, mechanical strength, and corrosion resistance. Choosing the right aluminum alloy is crucial for pharmaceutical packaging, as it directly impacts the preservation of the drugs.

Cold Form Foil (25 µm OPA/47 µm Alu foil/60 µm PVC) is a high-performance material with a multi-layer composite structure, widely used in pharmaceutical packaging, particularly for drugs sensitive to light and humidity.

OPA Layer (25 µm)

• Material Properties: The OPA (Oriented Polyamide) layer, with a thickness of 25 µm, provides excellent airtightness and moisture barrier properties. OPA material has high mechanical strength, effectively protecting drugs from external moisture and gases, maintaining the quality of the drugs.
• Function: The OPA layer enhances the barrier properties of Cold Form Foil, preventing external gases such as oxygen from entering the package and avoiding drug oxidation. Its moisture barrier properties are particularly suitable for drugs sensitive to humidity.

Aluminum Foil Layer (47 µm)

• Material Properties: The aluminum foil layer has a thickness of 47 µm, and this thickness further enhances the protective performance of the material. Aluminum foil provides strong barrier properties, especially in blocking oxygen, moisture, and light. The increased thickness of the aluminum foil layer allows the material to provide more stable and robust protection.
• Function: The addition of the aluminum foil layer significantly improves the oxygen, moisture, light, and environmental shielding properties of Cold Form Foil. This is particularly important for pharmaceutical packaging, especially when drugs need to be stored for long periods. The aluminum foil effectively extends the shelf life of drugs and prevents the loss of efficacy.

PVC Layer (60 µm)

• Material Properties: The PVC (Polyvinyl Chloride) layer has a thickness of 60 µm, providing sufficient mechanical strength to protect the internal drugs from external physical damage. PVC material has good formability and toughness, ensuring that Cold Form Foil remains stable during transportation and use.
• Function: The primary function of the PVC layer is to provide structural strength and protection. It ensures the stability of the packaging material, preventing damage or deformation caused by external forces. Additionally, the mechanical strength of the PVC layer makes Cold Form Foil suitable for applications requiring high-strength packaging.
