There are many different kinds of ointments on the market, but they are generally packaged in aluminum tubes. This is why? Aluminum skin is easy to break, and the cost is also high choose plastic packaging is not very good, Ziyang writer for you to answer. The main can be explained by the following aspects.
To improve the shelf life of pharmaceuticals.
Most drugs are susceptible to oxidation, decomposition, deterioration and fear of light, so high barrier packaging materials are needed.
Aluminum has a strong barrier, so some chemically unstable drugs are generally packaged in aluminum, which also has good light shielding, moisture resistance, airtight, corrosion resistance, non-toxic and tasteless characteristics, while the structure of aluminum oxide is very dense, can protect the internal aluminum from oxidation, but also to eliminate the chemical reaction between the drug and the packaging material.
Why not use plastic packaging ointment?
-Some plastics are transparent or translucent and can transmit trace amounts of light and ultraviolet light. The plastic packaging will rebound after the ointment is extruded and draw air into the tube, while the good calendering of aluminum will not draw air after the ointment is extruded. -The ingredients filtered out from plastic may contaminate the medicine.
In summary, if the ointment is packaged in plastic, it will accelerate the aging and deterioration of the drug and reduce the shelf life. That's why the regulatory bodies of various countries are more cautious in using plastic materials.
