Comparison of two materials for oral liquid bottles

Oral liquid bottles are packaging containers used to store various oral liquids, such as Shuanghuanglian oral liquid, zinc gluconate oral liquid, etc. The performance of packaging is closely related to its processing raw materials. The commonly used raw materials for this kind of packaging are glass and polypropylene. So, what is the difference between these two materials?
First of all, from the perspective of the corrosion resistance of oral liquid bottle materials, glass and polypropylene can resist the corrosion of most acid and alkali solvents, and can also prevent the invasion of oxygen and other gases to the contents and prevent the volatile contents of the contents. Components evaporate into the atmosphere. Prevent foreign impurities from invading the inside of the package and causing pollution to the drug.

In terms of processing technology, polypropylene raw materials are relatively simple in molding, and can be processed into containers of various shapes. In the processing technology, injection blowing, injection molding and other processing methods are mostly used. The molding of glass material is more complicated, and it needs to go through complicated procedures such as cleaning and drying before being put into use.

In terms of transportation, the main components of glass are silica and other oxides, which are brittle and inconvenient to transport. The polypropylene raw material has good anti-drop performance, which can reduce the loss caused by transportation and reduce the transportation cost.
In summary, polypropylene oral liquid bottles are corrosion-resistant, easy to process, and easy to transport. They have gradually begun to replace glass materials and become a common raw material for oral liquid drug packaging.
