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 can prevent the volatile components of the contents from volatilizing into the atmosphere;
2. The glass bottle can be used repeatedly, which can reduce the packaging cost;
3. The glass can easily change the color and transparency;
4. Glass bottles are safe and hygienic, have good corrosion resistance and acid corrosion resistance, and are suitable for the packaging of 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 development of automatic glass bottle filling technology and equipment in China is also relatively mature, and the use of glass bottles to package fruit and vegetable juice beverages has certain production advantages in China.
