In our daily life, we will find a variety of packaging materials, such as plastic, rubber, paper, etc.
Compared with other packaging materials, glass packaging materials have their own unique characteristics, such as transparency, finish, barrier, chemical stability, temperature resistance, compatibility, regeneration, etc., and are irreplaceable packaging containers for some biological agents, which are widely used in lyophilizer bottles, powder injection bottles, water injection bottles, etc.
There are two main classifications of glass bottles, one is classified according to the composition of glass, which is divided into two categories: soda-lime glass and borosilicate glass, among which borosilicate glass can be divided into three categories: high borosilicate, medium borosilicate and low borosilicate glass. Another classification standard is classified according to the different production processes, divided into tube bottles and molded bottles, in which the tube bottles are cut and fired with glass tubes, and the molded bottles are produced with glass liquid with molds.
Because of the different classifications, a glass bottle can be called more than once, but it may refer to the same bottle. For example, Sinovac's new crown vaccine bottle, its material is medium borosilicate glass, so it can be called medium borosilicate glass bottle; Its manufacturing process is made by tube drawing technology, which can also be called a tube bottle. So, the same bottle may be called by multiple names.
Due to the wide variety of packaging materials, large demand, the whole industry is flooded with many production enterprises, so the packaging market pattern is the coexistence of large and small enterprises, scattered operations, full competition characteristics. Due to the high entry threshold of molded bottles, especially the huge investment required to build kilns, and the production formula also has a high technical threshold, this advantage will be further concentrated in leading enterprises with the consistency evaluation of injections in the next step.
The market of control bottles is much more complicated, because the threshold for the entry of control bottles is very low, glass tubes of various materials can be purchased from the market, the price of the main equipment tube bottle machine is not high, and there are many enterprises in the market, including some large-scale enterprises.
