Molded glass spirit bottles belong to the family of inorganic alumino-silicate glass materials, with a stable chemical composition primarily based on sodium–calcium–alumino-silicate glass and boron–alumino-silicate glass. Thanks to their excellent physical and chemical stability, these bottles do not dissolve, corrode, or deteriorate, making them an ideal packaging choice for both pharmaceuticals and spirits.
At QLT Glass Products Manufacturing Co., Ltd., we follow strict ISO standards and implement GB2828 sampling inspection protocols to guarantee the safety, durability, and consistency of every bottle we produce.
Molded Glass vs. Tubular Glass: Which Is Better?
In pharmaceutical packaging, molded glass bottles account for around 70% of antibiotic injection vials, while tubular bottles make up the remaining share (China Medical News, 2003). This proportion is steadily increasing in favor of molded bottles due to several advantages:
-
Molded Glass Bottles: Cost-effective, strong, chemically stable, ideal for mass use in pharmaceuticals and spirits.
-
Tubular Glass Bottles: More visually appealing, but significantly more expensive and fragile.
