Glass is an ancient building material, which appeared as early as ancient Egypt. With the common development of human society, the glass profession has created various kinds of glass with unique functions, which makes the glass clan flourish constantly, such as bullet-proof glass, photoelectric glass, vacuum glass, etc., all playing an irreplaceable role in their respective fields. We will introduce the advantages of glass bottles as containers, and explain how to recognize the quality of glass bottles.
I. What are the advantages of glass bottle containers?
1. Glass materials have good barrier properties, which can prevent oxygen and other gases from invading the inner contents, and together can prevent volatile components of the inner contents from volatilizing into the atmosphere.
2. Glass bottles can be used repeatedly, which can reduce the cost of packaging.
3. Glass can easily change color and transparency.
4. Glass bottles are safe and hygienic. They have good corrosion resistance and acid resistance. They are suitable for packaging acid substances (such as vegetable, juice, beverage, etc.).
5. In addition, because glass bottles are suitable for active filling production line, domestic glass bottle active filling technology and equipment development is more sophisticated, using glass bottles to package fruit and vegetable juice beverages has certain production advantages in China.

2. How to Recognize the Quality of Glass Bottles
1. Listen to the sound. When you hit a glass bottle with your hand, you will hear different sounds. In a wine bottle factory, the tone of crystal material is higher, and there will be a feeling of aftertone winding around the beam, while the tone of glass products is lower and no echo.
2. Look at the weight of the utensils. For the same volume of utensils, the crystal material is heavier than the glass material, and the glass is lighter.
3. Look at the refractive index. Under the same light, the refractive index of crystal products is higher than that of glass products. It can transmit rainbow light, but the glass products can not get color light. The quality standard of glass bottles can be analyzed and judged from the product quality standard of the manufacturer.
4. Specific hardness. Crystal is harder than glass, so when you scratch the surface of glass with crystal, you will leave a trace, but when you scratch the crystal with glass, there is no such trace.
