Glass packaging bottle raw materials and production method

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

        The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone and so on. The glass bottle has a high degree of transparency and corrosion resistance, and the material properties will not change in contact with most chemicals. The manufacturing process is simple, the shape is free and changeable, the hardness is large, heat-resistant, clean, easy to clean, and can be used repeatedly. As packaging materials, glass bottles are mainly used for food, oil, wine, beverages, condiments, cosmetics, and liquid chemical products, etc., with a wide range of uses. However, glass bottles also have its disadvantages, such as large weight, high transportation and storage costs, and not impact resistance.
