As an external packaging material, medical aluminum foil is often processed into the form of blister. Blister packs are often used as unit dose packaging for tablets, capsules or lozenges. Blister packs can provide barrier protection for shelf life requirements, as well as some degree of tamper resistance. It is a good choice for pharmaceutical companies.

medical aluminum foil

In the United States, blister packs are primarily used to package physician samples of medicines or over-the-counter (OTC) products in pharmacies. In other parts of the world, blister packs are the predominant packaging type, as pharmacy dispensing and repacking are not common.

A series of blister cavities are sometimes referred to as blister cards or blister strips and blister packs. The difference between stick packs and blister packs is that stick packs have no thermoforming or cold forming cavities; stick packs are formed around the tablets as they fall into the sealing area between the sealing molds.

In some parts of the world, pharmaceutical blister packs are known as push-in packs (PTP), which is an accurate description of two key properties (i) the lid foil is fragile, so that the product can be pressed while the lid is opened A foil and (ii) a semi-rigidly formed cavity that is sufficiently collapsible to be able to dispense the tablet or capsule by pressing it out with the thumb. Breaking the cover foil with a fingernail for a suitable tablet will make pressing out easier.
