As domestic vaccines gradually enter the harvest period, the main contradictions in the vaccine field will shift from research and development and marketing to the industrialization of vaccines. This has given new opportunities and challenges to my country's pan-vaccine industry, requiring the entire industry chain to work together to safeguard the smooth implementation of vaccines. Pharmaceutical glass bottles play a key role in the use of vaccines. This paper provides a reference for investment in the pharmaceutical glass bottle industry by studying the supply and demand of pharmaceutical glass bottles for vaccines.

● Are there not enough glass bottles for medicine?

The glass bottles seem to be on the verge of running out.

In April, John Bell, professor of medicine at Oxford University, said there were only 200 million vials left. In early July, Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, said in an interview: “The production of glass bottles for vaccines is more difficult than for vaccines.”

Regarding the problem of vaccine bottles, the China Vaccine Association pointed out after investigation that my country's annual production of vaccine bottles can reach at least 8 billion. The Vaccine Association report pointed out“Due to the special characteristics of the vaccine, the packaging material chosen is borosilicate glass, which is mainly divided into two types: controlled injection bottles (silin bottles) and pre-filled syringes. There are more than 60 related packaging production enterprises in my country, among which the manufacturers of controlled injection bottles for vaccines mainly include Ningbo Zhengli, Shuangfeng Greensheim, etc., and the manufacturers of pre-potted syringes mainly include Shandong Weigao, Ningbo Zhengli, Shandong Yaobo, Bidi, etc. Based on the production capacity of enterprises, preliminary estimates indicate that my country's annual production of vaccine bottles can reach at least 8 billion.”

● Concept of medicinal glass bottle

Pharmaceutical glass bottles are vaccines, blood, biological agents, etc. Packaging can be divided into molded bottles and controlled bottles in terms of processing methods. Molded bottles refer to the use of molds to make glass liquid into medicine bottles, and controlled bottles refer to the use of flame processing and molding equipment to make glass tubes into pharmaceutical packaging bottles of a certain shape and volume. For molded bottles, Shandong Pharmaceutical Glass is a sub-sector of molded bottles, with a market share of 80%; for controlled bottles, Zhengchuan Co., Ltd. is one of the domestic enterprises in the controlled bottle sub-sector. In 2019, the production capacity of controlled bottles of medicinal glass was 8 billion, and the market share of medicinal bottles reached 80%; for controlled bottles, Zhengchuan Co., Ltd. is one of the domestic enterprises in the controlled bottle sub-sector. The market share of molded bottles reached 80%; for controlled bottles, Zhengchuan Co., Ltd. is one of the domestic enterprises in the controlled bottle sub-sector.

From the perspective of material and performance, pharmaceutical glass bottles can be divided into borosilicate glass and soda-lime glass. Soda-lime glass is easily shattered by impact and cannot withstand drastic temperature changes; while borosilicate glass can withstand large temperature differences. Therefore, borosilicate glass is mainly used for the packaging of injectable drugs.
