Glass bottle is a traditional beverage packaging container in China, and glass is also a kind of packaging material with a long history. In the case of many kinds of packaging materials flooding into the market, glass containers still occupy an important position in beverage packaging, which is inseparable from its packaging characteristics that cannot be replaced by other packaging materials.

As a packaging material, glass bottles are mainly used for food, oil, alcohol, beverages, condiments, cosmetics and liquid chemical products, etc. The main characteristics of glass bottles are: non-toxic, tasteless; Transparent, beautiful, good barrier, airtight, rich and common raw materials, low price, and can be used repeatedly. 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 costs, and impact resistance. The main raw materials of glass bottles are natural ores, quartzite, caustic soda, limestone, etc. Glass bottles have high transparency and corrosion resistance, and will not change the material properties when contacting with most chemicals.

The glass bottle is simple in manufacturing process, flexible in shape, high in hardness, heat resistant, clean, easy to clean, and reusable. First of all, we need to design, determine and manufacture the mold. The raw material of the glass bottle is quartz sand, and other auxiliary materials are dissolved into liquid under high temperature. Then the essential oil bottle is injected into the mold, cooled, cut, and tempered to form the glass bottle. The glass bottle generally has a rigid sign, which is also made of mold shape. The molding of glass bottles can be divided into manual blowing, mechanical blowing and extrusion molding according to the manufacturing methods.
