Application Fields And Process Characteristics Of Glass Bottles

Glass bottle is a traditional beverage packaging container in my country, and it still occupies an important position in beverage packaging. Its main raw materials are natural ore, quartz stone, caustic soda, limestone, etc., and it has high transparency and corrosion resistance, and the material properties will not change in contact with most chemicals. At present, glass bottles are mainly used in food, oil, alcohol, beverages, condiments, cosmetics and liquid chemical products, etc., and are widely used. Its characteristics are: non-toxic, odorless; transparent, beautiful, good barrier, airtight, abundant and common raw materials, low price, and can be used multiple times. In addition, glass bottles also have the advantages of heat resistance, pressure resistance and cleaning resistance, which can be sterilized at high temperature and stored at low temperature. However, glass bottles also have their shortcomings, such as heavy weight, high transportation and storage costs, and impact resistance.

The glass bottle has the advantages of simple manufacturing process, free and changeable shape, high hardness, heat resistance, cleanliness, easy cleaning, and can be used repeatedly. First of all, it is necessary to design and manufacture the mold. The raw material of the glass bottle is quartz sand as the main raw material, and other auxiliary materials are melted into a liquid state at high temperature, and then the essential oil bottle is injected into the mold, cooled, cut, and tempered to form a glass bottle. Glass bottles generally have rigid signs, which are also made from mold shapes. The molding of glass bottles can be divided into three types: manual blowing, mechanical blowing and extrusion molding according to the production method.
