Cold forming is a process used to manufacture pharmaceutical blister packages in which the foil is formed into a cavity or blister shape without the need for heating. Whether 30 micron aluminum foil is suitable for cold-formed medical foil depends on the specific requirements of the medical packaging application, and the choice of foil thickness is an important consideration in the process.

The thickness of aluminum foil determines the performance of pharmaceutical packaging:

Material properties: Aluminum foil properties, such as tensile strength, elongation and formability, are critical for cold forming. Thinner foils are generally better suited for cold forming because they are more flexible.

Cold Forming Ability: Thinner foils are generally better for the cold forming process because they can be formed easily without requiring excessive force. However, the specific requirements of the forming process, including the complexity of the formed shape, also play a role.

Barrier properties: Foils used in medical packaging must provide an effective barrier against moisture, light and gas to ensure the stability and safety of pharmaceutical products. The barrier properties of thinner foils may be slightly reduced compared to thicker foils and this should be considered based on the specific packaging needs.

Regulatory Compliance: Medical packaging materials, including aluminum foil, are subject to strict regulatory requirements. It is important to ensure that the chosen foil complies with relevant standards and regulations for medical packaging.

Compatibility with drugs: Certain drugs may have specific requirements for the packaging materials used. It is important to ensure that the aluminum foil chosen is compatible with the drugs it comes into contact with.
