Blisters with pills: how are they being manufactured and what requirements must be met?
Diseased persons take various medicines on a daily basis. Those could be the medicines advised by the doctor because of some specific illness, but not always – sometimes these are simply some minor supplements.
Some people, being curious about the world wonder how are these medicines boxed and why in this way.
The medicine is often acquired in a carton packaging. Inside, several blisters and printed guidelines are put. Why blisters? Firstly, they protect the drug from outside environment: moisture and pollution. Its material is not picked at will. It is polymer or aluminium. Chemical compounds, like PVC and its combinations with another substances are applied. They can be easily shaped by specialized appliances in very hot conditions. When the desired shape of the packaging is ready, the tablets are put into it. Finally, they are covered with the lid. It is usually fabricated from aluminium or polymer foil. During tablet packaging process, a wide range of factors has to be taken under consideration. The substrate material which is applied must not enter any reaction with the drug. It has to be durable enough to prevent the pills from cracking. At the same time the final packaging must be easy to use. Older patients have to be able to unpack it without bigger trouble, but not the children. It is not easy to design such sort of blister.
Materials for 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, as well as no intrusion into it was made. The user safety is the crucial goal.
