The Glass Bottle Production Process Mainly Includes Those

① Raw material preprocessing. Crush bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.), dry wet raw materials, and remove iron from iron-containing raw materials to ensure glass quality. ② Batch material preparation. ③ Melting. The glass batch material is heated at a high temperature (1550~1600 degrees) in a pool kiln or pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements. ④ Forming. Put the liquid glass into the mold to make glass products in the required shape, such as flat plates, various utensils, etc. ⑤ heat treatment. Through annealing, quenching and other processes, eliminate or generate stress, phase separation or crystallization inside the glass, and change the structural state of the glass.
Field advantages
Advantages of glass packaging containers in the field of beverage packaging
Glass packaging materials and containers have many advantages: 1. Glass materials have good barrier properties, which can well prevent the invasion of oxygen and other gases to the contents, and at the same time prevent the volatile components of the contents from volatilizing into the atmosphere;
2. Glass bottles can be used repeatedly, which can reduce packaging costs;
3. Glass can be easily changed in color and transparency;
4. Glass bottles are safe and hygienic, have good corrosion resistance and acid corrosion resistance, and are suitable for packaging acidic substances (such as vegetable juice drinks, etc.);
5. In addition, because glass bottles are suitable for the production of automatic filling production lines, the domestic glass bottle automatic filling technology and equipment are relatively mature, and the use of glass bottles to package fruit and vegetable juice beverages has certain production advantages in China.
