Why are tablets packed with aluminium foils?

Tablets are packed with aluminium foils for various reasons. One of the main reasons is to protect the tablets from external factors such as moisture, air, and light. These factors can alter the chemical composition of the tablets and reduce their effectiveness.

Moisture is a major issue for tablets as it can cause them to dissolve or break apart. Once the tablets come into contact with moisture, they start to undergo hydrolysis, which is a chemical reaction that breaks down the active ingredients in the tablet. This reduces the effectiveness of the tablet, rendering it useless. Hence, aluminium foil is used as a protective barrier to prevent moisture from reaching the tablet.

Tablets can also be affected by air. When tablets are exposed to air, they start to undergo oxidation and chemical reactions that can alter the properties of the tablets. This can lead to a reduction in the effectiveness of the tablet or even make them harmful to consume. Aluminium foil is impermeable to air and creates an airtight seal around the tablets, preventing them from undergoing oxidation and other chemical reactions.

Light can also be a problem for tablets. When tablets are exposed to light, they start to undergo photodegradation, which is a chemical reaction that breaks down the active ingredients in the tablet. This can make the tablet ineffective or even harmful to consume. Aluminium foil is opaque and does not allow light to pass through, thus preventing photodegradation from occurring.

In addition to the above reasons, aluminium foil is also used to keep the tablets fresh and free from contamination. Since aluminium foil is a non-toxic material, it does not react with the tablets or release any harmful substances into them. Additionally, aluminium foil is lightweight, flexible, and easy to handle, which makes it an ideal material for packaging and transporting tablets.

Another reason why tablets are packed with aluminium foils is that it provides a barrier against electromagnetic interference. Tablets contain electronic components such as sensors and processors, which can be affected by electromagnetic waves. These waves can cause interference, leading to malfunctioning of the tablet's electronic components. The aluminium foil helps to shield the tablets from these waves and prevent any interference.

Overall, aluminium foil is an excellent packaging material for tablets due to its properties and benefits. It helps to protect the tablets from external factors, keep them fresh and free from contamination, and provide a barrier against electromagnetic interference. The use of aluminium foil ensures that the tablets remain effective and safe for consumption, making it an essential component in the pharmaceutical industry.
