To increase the shelf life of medicines.

Most medicines are easily oxidized, decomposed, deteriorated, and sensitive to light, so high-barrier packaging materials are required.

Alu Alu foil has strong barrier properties, so some medicines with poor chemical stability are generally packaged with Alu Alu Foil. The aluminum inside is protected from oxidation, and chemical reactions between the drug and the packaging material are prevented.

Why not use plastic sheet?

1. The permeability coefficient of plastic packaging to oxygen and carbon monoxide is relatively large.

2. Plastic products are generally organic materials, which are easy to age.

3. Some plastics are transparent or translucent, which can transmit trace amounts of light and ultraviolet rays.

Elements leaching out of plastics may contaminate medicines.

To sum up, if the medicine is packaged in plastic, the aging and deterioration of the medicine will be accelerated, and the shelf life will be shortened. Therefore, drug regulatory agencies in various countries are more cautious in using plastic materials.

Of course, plastics also have many advantages over metal, such as the subject said that it is not easy to break, and the cost is low.

With the continuous emergence of new materials, new processes, new technologies and new products, plastic materials will solve various problems sooner or later. At present, the development of medical plastic packaging materials is accelerating, and the prospects are very broad. Better packaging materials may replace aluminum foil packaging. , and even nano-packaging materials will appear in the future.
