Description

technical field [0001] The invention belongs to the technical field of pharmaceutical packaging, a medicinal glass tube and a manufacturing method thereof. Background technique [0002] With the development of the pharmaceutical industry and the rapid advancement of science and technology, the corresponding technical requirements for the packaging of pharmaceutical products, especially glass bottles for liquid medicines, are also getting higher and higher. In the known technology, the existing medicinal glass tubes used for packaging liquid medicines such as glass bottles are mainly fuel-heated glass melting methods. The glass liquid temperature measured by the temperature measuring instrument has a large error and is easily corroded by high-temperature glass liquid. The impurities brought in are limited by its ingredients and process methods. The expansion coefficient of the produced glass tubes for medicine is small. The glass bottles made of its glass tubes are used to ho...
