Comparison of mainstream materials for glass bottles

[ February 27, 2026 ]

In the production and manufacturing of glass bottles, borosilicate glass and soda-lime glass are the two most widely used materials. The differences in composition and process between the two have led to significant variations in performance, applicable scenarios and costs, which have become the key materials for selection under different demands. In terms of core performance, borosilicate glass has advantages in many aspects. It has higher transparency and can better display the contents. Its strength and hardness are superior to those of sodium-calcium glass, and it has a stronger resistance to external pressure and is less likely to break. Its low coefficient of thermal expansion makes it highly heat-resistant, capable of withstanding high-temperature environments without cracking or deforming. At the same time, it has a higher porosity and better air permeability, which is suitable for special storage requirements. Although soda-lime glass is slightly inferior in performance, it has the core advantage of low cost and is suitable for large-scale production and ordinary scenarios. It is the mainstream choice for regular containers such as beverage bottles and ordinary food bottles. However, soda-lime glass is relatively brittle and has poor heat resistance, making it unsuitable for high-temperature storage scenarios. It is also not suitable for storing items that require breathability and impact resistance. In terms of cost, the manufacturing cost of borosilicate glass is much higher than that of soda-lime glass, which also determines that its application is mostly concentrated in high-end and special demand fields, such as pharmaceutical packaging, laboratory vessels, high-end cosmetic bottles, etc. Soda-lime glass is widely used in ordinary storage containers for daily civilian use, meeting the basic needs of the general public.
