Glass bottle is a traditional beverage packaging container in China, and glass is also a historical packaging material. When many kinds of packaging materials pour into the market, glass container still occupies an important position in beverage packaging, which is inseparable from its packaging characteristics that can not be replaced by other packaging materials.
As a packaging material, glass bottles are mainly used in food, oil, wine, beverage, condiment, cosmetics and liquid chemical products. The main characteristics of glass bottles are: non-toxic and tasteless; Transparent, beautiful, good barrier, airtight, rich and common raw materials, low price, and can be reused for many times. Glass bottles have the advantages of heat resistance, pressure resistance and cleaning resistance. They can be sterilized at high temperature and stored at low temperature. However, glass bottles also have their disadvantages, such as heavy weight, high transportation and storage cost, impact resistance and so on. The main raw materials of glass bottles are natural ore, caustic soda, limestone, etc. The glass bottle has high transparency and corrosion resistance, and the material properties will not change in contact with most chemicals.
The glass bottle has the advantages of simple manufacturing process, free and changeable shape, high hardness, heat resistance, cleanness, easy cleaning, and can be used repeatedly. First, the mold should be designed, determined and manufactured. The raw material of the glass bottle is quartz sand as the main raw material and other auxiliary materials melt into liquid at high temperature. Then the essential oil bottle is injected into the mold, cooled, cut and tempered to form the glass bottle. Glass bottles generally have rigid marks, which are also made of mold shape. According to the manufacturing methods, the molding of glass bottles can be divided into manual blowing, mechanical blowing and extrusion molding.
