Diseased persons use various medicines very often. They can be the drugs prescribed by the doctor because of some diagnosed illness, but not always – sometimes these are simply some vitamins.
Some patients, being curious about all sorts of things wonder how are these medicines boxed and why in this way.
The medication is often bought in a cardboard packaging. Within, several blisters and printed guidelines can be found
. Why blisters? First of all, they protect the medicine from
outside environment: moisture and dirt. The material is not picked randomly. It is plastic or aluminium. Chemical compounds, like PVC and its blends with another substances are used. They can be quickly formed with the help of special machines under high temperature conditions. After the wanted shape of the blister is ready, the tablets are put inside
it. Then, they are closed by the lid. It is usually fabricated from aluminium or polymer foil. During tablet packaging process, a lot of factors must be taken into account. The substrate material which is used must not react with the drug. It has to be tough enough to protect the tablets from cracking. At the same time the final packaging must be user-friendly. Elderly patients must be able to unpack it without any trouble, but not the kids. It is quite difficult to design (see aprogroup ltd
) this sort of blister.
Materials in medicine and pharmacy have to meet specific, strict requirements.
Thanks to this fact patients can count that the medicine they acquire is properly packed, isolated, and nobody attempted any intrusion inside. The safety of users is the crucial goal.
