In addition to all kinds of plastic or glass bottles, aluminum foil blister packaging is the most used one. Aluminum alloy is generally used in the production of aluminum foil bubble cover packaging, which has a good performance in mechanical properties and pinhole density. Its roughness and glossiness are better than pure aluminum foil, which is beneficial to surface printing and decoration. Blister packaging has many advantages. Pirmkārt, blister packaging can separate drugs and provide patients with one-dose drug packaging, which is convenient and economical. Turklāt, PTP aluminum foam cover packaging protection drug performance is good, production speed is fast, the cost is relatively low, storage accounted for a small space, viegls, transportation is very convenient.

Drug PTP aluminum foil has non-toxic, tasteless, lightweight material characteristics, processed out of the finished product has a good shading effect than the traditional brown glass bottles, because the pinhole density on the aluminum foil is fine, has high moisture resistance and barrier. Aluminum foil water vapor transmittance is very low, completely opaque, can effectively avoid harmful effects of ultraviolet light. Its air resistance, moistureproof, shading, and incense retention greatly exceed plastic, papīrs, and other types of packaging materials. Tāpēc, gold aluminum can maintain the quality of goods for a long time, and this metal will not cause any harm to the human body, PTP medical aluminum foil base material can be generally divided into hard aluminum foil and soft aluminum foil. Hard aluminum foil is mostly used for blister packaging of tablets and capsules, while the soft aluminum foil is generally used for outer packaging of powdery particles and powdery composite soft packaging.

Because the surface of foam-pack aluminum foil can be printed with text instructions, the phenomenon of wrong drug delivery can be avoided in the process of dispensing various tablets. Tāpēc, blister packaging will be the main way of drug tablets, capsule packaging. Some blister packaging can be made into a transparent form, through which it is easy to see the shape and size of the medicine inside. The basic information such as commodity code, name, and so on can be printed on the substrate. This form can facilitate the identification and counting of equipment in the package, avoid sending and receiving errors, easy to use. In view of the excellent characteristics of aluminum foil, it is difficult to surpass aluminum foil in packaging, no matter any metalized film or coated special film can not completely replace aluminum foil.

Līdz ar farmācijas nozares attīstību, the technology of pharmaceutical packaging is becoming more and more sophisticated, and the quality requirements of pharmaceutical aluminum foil packaging are becoming higher and higher. Not only the material requirements, in the outer surface of packaging, such as the variety of printing colors, but also with the surface quality requirements of pharmaceutical aluminum foil are becoming higher and higher.
