## About

Founded in 1992 and based in Cangzhou, China, Cangzhou Four Stars Glass Co., LTD. manufactures pharmaceutical glass materials for use in injectable and liquid dosage packaging. The company was officially established in 2006 and has developed proprietary processes for neutral borosilicate glass tubes and localized production technologies for components used in prefilled syringe systems. It operates multiple production sites and has obtained more than ninety patents related to pharmaceutical glass. Cangzhou Four Stars Glass Co., LTD. supplies customers in the pharmaceutical packaging sector across China and international markets. In recent years, the company has expanded its production capabilities to support the industry shift from conventional glass materials to borosilicate based products. In April 2026, it raised over CNY 300 million in venture funding led by GTJA Investment Group.

The company works with pharmaceutical packaging firms and drug manufacturers to provide neutral borosilicate glass tubes, ampoules, vials, and molded glass containers. Its products include controlled injection bottles, screw top vials, fluted vials and oral liquid bottles. 

The company generates revenue through the sale of pharmaceutical glass tubes, vials, ampoules and molded containers.

The company will use the funding in April 2026 to advance the construction of the Guangxi Nanning Four Stars Pharmaceutical Intelligent Manufacturing Base, marking a strategic advancement in the field of high-end pharmaceutical packaging materials and accelerating the formation of a full-chain development pattern that connects upstream key materials with downstream application scenarios.
