Glass as Packaging Material
Glass packaging is a popular choice for pharmaceutical items because it is inert and impermeable, preventing external substances from entering the medication and maintaining long-term stability and effectiveness. Its transparency and visibility build trust and confidence, while its completely recyclable nature promotes environmental sustainability.
Composition of Glass
Glass used in pharmaceutical packaging is primarily composed of silica(sand), soda ash(sodium carbonate), limestone(calcium carbonate), alumina, and borax. Silica provides structural integrity, while soda ash lowers the melting point for shaping. Lime enhances chemical durability, and alumina improves mechanical strength. Borax modifies thermal properties for resistance to temperature changes.
Colorants and additives may be included to achieve specific properties such as transparency or UV protection. In pharmaceutical applications, glass composition is important for ensuring that containers maintain medication integrity. It must be inert, impermeable, and transparent, resisting breakage during sterilization. Clear or amber glass is widely used for easy inspection and light protection.
