Glass bottles have a high degree of transparency and corrosion resistance, 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 can be used repeatedly. As packaging materials, glass bottles are mainly used in food, oil, wine, beverage, seasoning, cosmetics and liquid chemical products. But glass bottles also have its disadvantages, such as large weight, high transportation and storage costs, impact resistance, etc. First of all to design and manufacture mold, glass material with quartz sand as the main raw material, plus other auxiliary materials in high temperature dissolved into liquid, and then injected into the mold, cooling, cutting, tempering, forming glass bottles. Glass bottles generally have rigid marks, which are also made of mold shapes. Glass bottle molding in accordance with the production method can be divided into artificial blowing, mechanical blowing and extrusion molding three.

Glass bottles can be divided into the following kinds according to the composition: one is sodium glass two is lead glass three is boron-silicon glass. The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone and so on.
