Why do more people choose aluminum foil blisterpackaging?

If you are in the pharmaceutical industry, you will find that brown medicine bottle packaging is less

and less, and more and more are aluminum foil blister packaging. Have you ever wondered why?

Medicine is indispensable to people, and the way and materials of medicine packaging have gradually changed. In recent years, the aluminum-plastic blisterpackaging of medicines has been rapidly developed in our country. Because of the characteristics of long storage period and convenient carrying, this kind of packaging is more and more popular with pharmaceutical companies and consumers, and is gradually replacing traditional glass bottle packaging. And bulk packaging has become the mainstream of solid medicine packaging.

And why can aluminum-plastic blister replace traditional medical packaging?

Aluminum-plastic blister packaging, also known as blister packaging, is a new type of solid medicine packaging. After the transparent plastic hard sheet is blister-molded, the tablets, pills, capsules and other solid medicines are filled in the groove, and then heated and bonded with the adhesive-coated aluminum foil to form an independent sealed package. At present, many solid medicines are still packaged in glass bottles. Although they can prevent light, moisture, and oxidation, the packaging capacity is large and the technological content is not high.

For the more demanding special drugs, this traditional packaging form cannot effectively prevent the deliquescence of the drugs. This is also an important reason why large-capacity brown glass bottle packaging is rapidly delisting in recent years. Compared with bottled drugs, the advantage of blister packaging is that it is easy to carry and can reduce the pollution caused by the drug in the process of carrying and taking. Moreover, the blister packaging has the advantages of gas barrier, moisture permeability, hygienic safety, production efficiency, and dosage accuracy. It also has obvious advantages in terms of extending the shelf life of drugs.

The good barrier properties of blister packaging are due to its choice of raw materials, aluminum foil and plastic rigid sheets. The aluminum box has a highly dense metal crystal structure with good barrier properties and light-shielding properties; the plastic rigid sheet must have sufficient barrier properties against oxygen, carbon dioxide and water vapor, high transparency, and mechanical strength that is not easy to crack. . At present, common medical blister packaging materials are PVC sheets and PVDC (polyvinylidene chloride).

In addition, the material of a kind of blister packaging is vacuum aluminized film, which is a kind of film that deposits aluminum vapor on the base film in a high vacuum state. Currently, PET, CPP, PVC, 0PP, PE, etc. are widely used.

As the base film of vacuum aluminized film, in addition to the characteristics of the original base film, the aluminized film also has beautiful decoration and better barrier properties. The light transmittance, oxygen transmission rate and moisture transmission rate are only the original base. A few tenths or even one percent of the film is also one of the key development directions for blister packaging materials in the future.
