Comparative advantages of aluminum tube packaging and other packaging forms for medicinal ointments

Compared with composite tubes, aluminum tubes have the outstanding advantage of excellent air tightness. Because the aluminum material is dense, and the aluminum tube is formed by one-time punching and extrusion of a single material, there is absolutely no possibility of leakage at the welded joints of different materials of the composite tube. In contrast, the manufacturing process of composite tube is complex, with longitudinal welds welded on the pipe body, and the injection of two different materials for the pipe body and the pipe shoulder. Due to the unstable process, it is difficult to reliably ensure the airtightness of each individual product in mass production. . Moreover, the composite tube also has a “rebound” phenomenon, which causes a large amount of unpurified air from the outside to enter the tube and directly contact the medicine, which inevitably leads to the possibility of secondary pollution that is taboo for medicine. In addition, the composite pipe cannot be sterilized at a temperature of nearly 500 degrees Celsius during the production process. In particular, there are considerable difficulties in its recycling and reuse, and it is difficult to degrade when discarded in nature, which does not meet the requirements of green environmental protection. This is a fatal shortcoming that restricts its further development.

If human society wants to survive in the cloud, it must quickly change the massive consumption and waste of resources. At the same time, traditional production methods that destroy the environment. With the rising voice of green environmental protection, the recycling of packaging materials is becoming more and more important and will be more noticeable. A great advantage of aluminum is that it is very easy to recycle.

To sum up, aluminum tube has its unique advantages and strong vitality. It will be the mainstream choice of pharmaceutical ointment packaging in the future. It also meets the requirements of ISO14000, improves and protects the environment, and promotes sustainable economic development.
