Why are many medicines packaged in aluminum?

Most drugs are easy to oxidize, absorb moisture, decompose and deteriorate, while the aluminum foil package has good shading and compactness, which can protect the inner package drugs from oxidation absorb moisture and deteriorate, and the pressure ductility is good, easy to produce and disassemble, and the cost is also relatively low.

Medicinal aluminum foil is mostly in the form of aluminum-plastic composite film to obtain better moisture resistance and flexibility, also considering the health properties of drugs.

Although aluminum readily reacts with oxygen in the air to form aluminum oxide, the structure of this layer of aluminum oxide is so dense that it can protect the inner aluminum from oxidation.
