Pharmaceutical glass materials and containers (PGMC), as part of drugs, are used for packaging materials in direct contact with various pharmaceutical preparations.

Glass is one of the most chemically stable materials. It is an amorphous and transparent solid material formed by cooling down the high-temperature fusion.

Glass is widely used in the packaging of various pharmaceuticals because it possesses a number of advantages, such as excellent hydrolytic resistance and acid resistance, average alkali resistance, optimal thermal stability, desired mechanical strength. It is also smooth and transparent, easy to clean and sterilize, superior in barrier property, and easy to seal.

PGMC can be classified according to chemical composition and properties, water resistance, molding methods, etc.
