MC Aluminum produces industrial pure aluminum foil for pharmaceutical packaging, usually with a thickness of 0.02mm, a tensile strength of 98kPa, and a breaking strength of 90kPa. The surface is clean, flat, wrinkle-free, indentation-free, phosphor-free, and the surface wetting tension is not less than 32. Aluminum foil for pharmaceutical packaging is made of 99% electrolytic aluminum and processed by time delay and other methods. It is non-toxic and odorless, has high-quality electrical conductivity and light-shielding properties, and has extremely high moisture resistance and gas barrier properties.
The quality requirements for aluminum foil for pharmaceutical packaging are extremely strict, especially in ensuring the stability and safety of drugs, focusing on the following aspects:
1. Pinhole requirements
The pinhole requirements for aluminum foil are extremely high, and the number of pinholes with a diameter of 0.1-0.3mm should not exceed 1 per square meter. Since the pinholes on the aluminum foil are potential air permeability points, which will lead to the penetration of oxygen, water vapor and light, affect the stability of the drug, and even reduce the efficacy, the control of pinholes is of utmost importance.
2. Thickness uniformity
The thickness of the aluminum foil must be precise, and the deviation must not exceed 10%. Uneven thickness will affect the coating quality of the adhesive layer and the protective layer after lamination, and then affect the overall performance of the drug packaging, including sealing, protection and barrier properties.
3. Surface treatment
The surface should be flat and smooth, and there should be no obvious scratches, depressions or oxidation spots.
The surface flatness shall not exceed 0.005mm, and the surface finish shall not be less than Ra 0.6.
4. Microbial contamination
The total bacterial count of the aluminum foil shall not exceed 10 CFU/g, and it should not contain microorganisms from the external environment to ensure the hygiene and safety of the drug.
