Why do pharmaceutical packaging use aluminum foil?


Why do pharmaceutical packaging use aluminum foil?

Aluminum foil is widely used. The thickness of medical foil is 0.006-0.02mm. Aluminum foil is compounded, coated, and printed to produce finished products. Compared with other raw materials, aluminum foil has better moisture resistance. At the same time, aluminum foil has good heat insulation performance. Best of all, aluminum is non-toxic and non-adsorptive, which minimizes bacterial growth

When pharmaceuticals are packaged, it is important to maintain the quality and safety of pharmaceuticals. Aluminum foil is a commonly used material because it has the following advantages:

1. Good barrier performance: Aluminum foil can effectively prevent medicines from moisture and humidity, because it is an impermeable material that can keep medicines dry and stable. In addition, aluminum foil can also prevent oxygen and other gases from entering pharmaceutical packaging, thereby maintaining the stability and active ingredients of pharmaceuticals. Some pharmaceuticals deteriorate when they come in contact with oxygen, so aluminum foil can help protect their quality.

2. Aluminum foil has good heat insulation performance: Aluminum foil is an excellent heat insulation material, which can help maintain the active ingredients and efficacy of medicines. Medicines usually need to be stored at low temperatures, and aluminum foil can protect medicines from high temperatures.

3. High degree of recognition: Aluminum foil can make pharmaceutical packaging easier to be recognized and identified. At the same time, aluminum foil can also be used in anti-counterfeiting packaging to ensure the authenticity and safety of medicines.

4. Protect drug stability and extend shelf life

When drugs come into contact with the surrounding environment, they are easily affected by factors such as moisture, air, and light, which can lead to problems such as decomposition, oxidation, and deterioration of drugs. These problems can affect the effectiveness and safety of the drug. Therefore, medicines need to be packed with substances that can prevent the invasion of these harmful factors to maintain long-term stability. Aluminum foil has extremely low oxidative properties, thus protecting pharmaceuticals from oxidation, thus ensuring the quality and effectiveness of pharmaceuticals.

5. Protect privacy
Some medicines may cause some privacy issues, so they need to be packaged tightly to protect the privacy of users. The use of aluminum foil packaging can completely seal medicines, prevent medicines from leaking, and protect users’ privacy.

As an excellent packaging material, aluminum foil can help protect the quality and safety of drugs, reduce contact and pollution between drugs and the external environment, and extend the shelf life of drugs. At the same time, aluminum foil can also be used in combination with other materials to form a multi-layer composite material to further improve the performance and function of pharmaceutical packaging.
