Whether the packaging of medicines is intact determines the quality and safety of medicines, and also affects the health of users. The packaging of medicines needs to be able to safely protect medicines from environmental influences, oksygen, and moisture. Only in this way can pharmaceutical packaging be used to maintain effective pharmaceutical properties when ingested.

A commonly used packaging for pharmaceutical packaging is aluminum foil blister packaging. This packaging allows each tablet to be opened independently without affecting the subsequent use of other drugs. It also includes the push-in blister that is often used nowadays. This kind of packaging is a molded plastic used for a single tablet cavity, and its seal is made of aluminum foil. It is also called a blister aluminum film or It is an aluminum cover film. Because of the good preservation characteristics of medicines, commonly used medicine capsules and medicine tablets can be well protected.

Aluminum foil blister packaging is actually a very practical and convenient way of packaging medicines.

Because the blister is made of aluminum foil, which has low density and lightweight, the blister packaging we have seen is easy to carry. Due to the good ductility of aluminum foil, each product in the aluminum foil blister is individually packaged, and the use of each medicine does not affect each other.

With the widespread use of aluminum foil blister packaging and good product reputation, pharmaceutical manufacturers continue to upgrade their products in order to meet future user requirements in terms of reliability, hygiene, and quality of pharmaceutical packaging. With the improvement of technical means, drug coating or printing blister film has gradually become the mainstream method of use, which can not only add instructions for the use of drugs but also play a role in publicity and promotion to a certain extent.

For pharmaceutical manufacturers, the initial difficult problem to solve is that the plastic press-in blister must be airtightly sealed with an aluminum cover film. Only in this way can the tablets be effectively protected. To this end, the general approach is to apply a suitable sealant (usually a heat seal paint) on the aluminum foil. After putting the tablet into each hole of the blister mold, the aluminum foil is attached. After a suitable combination of heat sealing time, pressure, og varme, the heat sealing paint on the aluminum foil is combined with the plastic material of the blister. Both are perfectly sealed to protect the tablet from environmental factors.

On the other hand, in order to label drug information and promote enterprise products, drug packaging manufacturers often put primers on the finished blister packages, print the manufacturer’s logo or other drug information, so that users can quickly and safely identify drugs.
