Why does the packaging of drugs/medecines usually using aluminum foil?

Why does the packaging of drugs have to use aluminum foil?

The main reasons are as follows:

Firstly, aluminum foil has strong airtightness, stable properties, and good protective effects on drugs. Aluminum foil, also known as tin foil, has a high molecular density and can isolate water vapor, effectively isolating dust and moisture in the air, preventing corrosion and infection of drugs, and has good sealing properties. Many of the drugs we usually take should keep off moisture, such as capsules, effervescent tablets, film coated tablets, etc. Once these drugs are damped, their efficacy will be reduced, and they may even spoil and become moldy. Some drugs are prone to oxidation, and after oxidation, they will spoil. Although they may not appear on the surface, they will reduce their efficacy. These light sensitive drugs will be wrapped in aluminum foil to cover the entire medication board.

Secondly, it is convenient to use. Aluminum foil has good stretchability and is relatively easy to produce and disassemble. When we take medicine, if we cut it, the aluminum foil paper will break. However, if you try to cut the plastic, it will definitely be difficult to cut it open. The aluminum foil medicine board has many humanized designs, such as a groove in the middle, which first serves as a buffer and secondly prevents flipping inward, while crushing the tablet can only be flipped backwards; This design is unique in that it is designed for drug distribution. A box of drugs with a large quantity can be separated separately for easy carrying by patients.

To avoid light, remember to put the medicine back after taking it. On the other hand, if soft aluminum foil is used, greater force must be applied to reach the drug, as the stretching force of the film is higher. Therefore, bubble wrap packaging with covering foil made of soft aluminum is considered to be more effective in preventing children from ingesting it.

Thirdly, good safety and hygiene. Aluminum foil also ensures the hygiene of drugs to some extent due to its smooth surface, which makes it less likely to carry bacteria. The single dose packaging box facilitates patient counting and does not increase the risk of drug contamination due to the need to repeatedly pour out and in like bottled drugs during counting. Fourthly, aesthetics and corporate promotion. The printing suitability of medicinal aluminum foil is also required to be good, and various colors of text or patterns can be printed on both the light and dark sides of the aluminum foil. Seeing this, my friends understand why drugs must be packaged with aluminum foil!
