The blister z folii aluminiowej (PTP) packaging of medicines is also called blister packaging. The aluminum foil used is a sealing material sealed on a medicinal PVC hard sheet, and it is often called a lidding material. This packaging form has many advantages: Pierwszy, it can provide patients with one-dose medicine packaging, which is convenient and economical and solves the problem that medicines can be taken multiple times. The second point is that the production speed of blister packaging is very fast, the cost of production is low, the storage area is small, and the transportation is convenient. The third point is that this kind of packaging has good safety performance. Because the surface of the aluminum foil can be printed, the instructions for some drugs can be marked on the outer surface of the packaging. The advantage of this is that the wrong medicine can be avoided during the dispensing process of multiple tablets.

For all parts of the world, there will be more demand for better quality blister packaging. Naraz, it corresponds to the large increase in high-quality blister packaging in various regions to meet the needs of the pharmaceutical market. It is expected that this form of aluminum foil blister packaging will account for sixty-seven of the future pharmaceutical tablet and capsule packaging, and it is one of the pharmaceutical packaging forms with the best development prospects. Jednakże, although the development prospects are very good, the development of aluminum foil blister also faces many problems.

The raw material of aluminum foil blister is metal aluminum. It is made of electrolytic aluminum with a purity of 99% through a special rolling process. The products produced can have excellent characteristics such as odorless, good conductivity, light-shielding, odporność na wilgoć, and gas barrier properties. Naraz, because of the special metal crystal space structure of aluminum foil, it can block any gas, para wodna, i światło. This also just meets the special requirements of pharmaceutical packaging, ale obecnie, many manufacturers’ pharmaceutical packaging technology still does not reach the high-quality level. According to some actual pharmaceutical production data, the current aluminum foil blister packaging mainly contains the following Questions.

(1) The number of pinholes in medical aluminum foil cannot fully meet the requirements. The number of pinholes of aluminum foil determines the performance of aluminum foil packaging, and also determines whether this packaging can truly isolate air, para wodna, i światło. If these factors are not handled properly, they can easily penetrate the packaging layer and reduce the efficacy of the medicine. Dlatego, for medicinal aluminum foil, the international standard requires no pinholes with a diameter greater than 0.3 mm, and pinholes with a diameter of 0.1-0.3 mm cannot be more than 1 na metr kwadratowy. This is a process with high technical requirements.

(2) Medical aluminum foil has an uneven thickness and low tensile strength. If the thickness of the aluminum foil is unbalanced, the amount of adhesive applied during the coating process will not reach the standard, which will affect the heat-seal strength of the aluminum foil and PCV. The tensile strength is low, and it is easy to break the foil after winding tension, which is not conducive to production.
