1. Glass material has good barrier properties, can well prevent oxygen and other gases on the invasion of the contents, while preventing the contents of volatile components to the atmosphere volatile;
2. Glass bottles can be used repeatedly, can reduce packaging costs;
3. Glass can be easier to change the color and transparency;
4. Glass bottles of health and safety, good corrosion resistance and acid corrosion resistance, suitable for acidic substances (such as juice drinks, etc.) packaging.
Glass bottles are food, medicine, chemical industry, the main packaging container. They have good chemical stability; easy to seal, airtight, transparent, can be observed from the outside of the contents of the situation; good storage performance; surface smooth, easy to sterilize and disinfect; handsome in appearance, decorative rich and colorful; have a certain degree of mechanical Strength, can withstand the pressure inside the bottle and the external force in the process of transportation; raw materials are widely distributed, low price and so on. The disadvantage is the quality of large (mass and capacity than large), brittle, fragile. However, in recent years, the use of thin-walled lightweight and physicochemical new technology, these shortcomings have been significantly improved, so glass can be in the fierce competition with plastic, iron, iron cans, the output increased year by year.
