People use various medicines on a daily basis. They could be the drugs advised by the doctor because of some specific illness, but not necessarily – sometimes these are simply some vitamins.
Some patients, being curious about the world wonder how are those medicines packed and why in this way.
The medication is usually bought in a carton packaging. Inside, several blisters and the leaflet can be found. Why blisters? Firstly, they shield the drug from outside environment: moisture and pollution. The material is not chosen randomly. It is plastic or aluminium. Chemical compounds, for example PVC and its combinations with another substances are applied. They can be easily shaped with the help of specialized machines under high temperature conditions. After the desired shape of the packaging is ready, the pills are put into it. Finally, they are closed by the lid. It is usually fabricated from aluminium or plastic foil. During tablet packaging production, a wide range of factors must be taken under consideration. The raw material which is used should not react with the medicine. It has to be tough enough to protect the tablets from crushing. At the same time the final packaging must be easy to use. Elderly patients have to be able to unpack it without any problems, but not the kids.
