First of all, the mold should be designed, determined and manufactured. The glass raw material is quartz sand as the main raw material, and other auxiliary materials are melted into liquid at high temperature, and then injected into the mold, and cut and tempered to form a glass bottle. Glass bottles generally have rigid marks, which are also made of mold shapes. The molding of glass bottles can be divided into manual blowing, mechanical blowing and extrusion molding according to the manufacturing methods. Glass bottles can be divided into the following types according to their composition: sodium glass, lead glass and borosilicate glass.

The main raw materials of glass bottles are ore, quartz, caustic soda, limestone, etc. The glass bottle has high transparency and corrosion resistance, and will not change the material properties when contacting with most chemicals. Its manufacturing process is simple, its shape is free and changeable, its hardness is large, it is heat-resistant, clean and easy to clean, and it has the characteristics of being reusable. As a packaging material, glass bottles are mainly used for food, oil, alcohol, beverage, flavoring, cosmetics, liquid chemical products, etc., and are widely used. However, glass bottles also have its disadvantages, such as heavy weight, high transportation and storage costs, and impact resistance.
