Safety of glass bottles

Glass is an ancient building material, which has appeared as early as ancient Egypt. With the common development of human society, the glass industry has created a variety of glass with unique functions, which makes the glass family continue to flourish, such as bulletproof glass, photoelectric glass, vacuum glass, etc., which play an irreplaceable role in their respective fields. We will introduce the advantages of glass bottles as containers, and explain the methods to confirm the quality of glass bottles. 1、 What are the advantages of glass bottle container? 1. Glass materials have good barrier performance, which can well prevent oxygen and other gases from invading the contents, and prevent volatile components of the contents from volatilizing into the atmosphere; 2. The glass bottle can be used repeatedly to reduce the packaging cost; 3. Glass can easily change the color and transparency; 4. The glass bottle is safe and hygienic, has good corrosion resistance and acid resistance, and is suitable for packaging acidic substances (such as vegetable juice drinks); 5. In addition, because glass bottles are suitable for the production of automatic filling production lines, the development of domestic glass bottle automatic filling technology and equipment is relatively mature, and the use of glass bottles to package fruit and vegetable juice drinks has certain production advantages in China. 2、 How to confirm the quality of glass bottle 1. Listen to the sound When you hit the craft glass wine bottle with your hand, you can hear different sounds. In the wine bottle factory, the tone of the crystal material is high, which makes you feel the lingering sound, while the tone of the glass products is low and there is no echo 2. Look at the weight of the vessels. For vessels of the same volume, the crystal ones are heavier than the glass ones, and the glass ones are lighter 3. Look at the refraction Under the same light, the refractive index of crystal products should be higher than that of glass, which can transmit seven rainbow light, and glass products do not show colorful light. The quality standard of glass bottles can be used to analyze and judge the quality of products from the manufacturer’s product quality standard 4. Specific hardness The hardness of crystal is higher than that of glass, so when you use crystal to scratch the surface of glass, you will leave a trace, but when you use glass to scratch the crystal, there is no such trace.
