First of all, to design and manufacture mold, glass raw materials to quartz sand as the main raw material, plus other accessories at high temperature to dissolve into liquid, 

and then injected into the mold, cooling, cutting, tempering, the formation of glass bottles. Glass bottles generally have rigid signs, and the signs are also made of mold 

shapes. The molding of glass bottles can be divided into three kinds according to the production method: artificial blowing, mechanical blowing and extrusion molding. 

Glass bottles can be divided into the following types according to their composition: one is sodium glass, the other is lead glass, and the other is borosilicate glass.

The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone and so on. Glass bottles have a high degree of transparency and corrosion 

resistance, and contact with most chemicals will not change the material properties. Its manufacturing process is simple, free and changeable shape, high hardness, heat 

resistance, clean, easy to clean, and has the characteristics of repeated use. As a packaging material, glass bottles are mainly used in food, oil, alcohol, beverages, condiments, 

cosmetics and liquid chemical products, etc., and have a wide range of uses. But glass bottles also have its disadvantages, such as large weight, high transportation and 

storage costs, and impact resistance.
