Glass is a kind of packaging material with a long history, and glass bottles are also China’s traditional beverage packaging containers. When a variety of packaging materials pour into the market, glass container still occupies an important position in beverage packaging, because it has packaging characteristics that can not be replaced by other packaging materials, but its application began to decrease significantly. The main characteristics of glass packaging containers are: non-toxic, tasteless, transparent, beautiful, good barrier, airtight, rich raw materials, low price, and can be used repeatedly.
Glass bottle is the main packaging container in food, medicine and chemical industry. They have good chemical stability; Easy to seal, good air tightness, transparent, and the condition of the contents can be observed from the outside; Good storage performance; The surface is bright and clean, which is convenient for disinfection and sterilization; Beautiful appearance and colorful decoration; It has certain mechanical strength and can withstand the pressure in the bottle and the external force during transportation; It has the advantages of wide distribution of raw materials and low price. Its disadvantages are large mass (large ratio of mass to capacity), brittleness and fragility. However, these shortcomings have been significantly improved by using the new technology of thin-wall lightweight and physical and chemical tempering. Therefore, the output of glass bottles can increase year by year under the fierce competition with plastics, iron cans and iron cans.
Moreover, it has the advantages of heat resistance, pressure resistance and cleaning resistance. It can be sterilized at high temperature and stored at low temperature. Because of its many advantages, it has become the first choice for many drinks with high requirements for packaging containers, such as fruit tea, wild jujube juice and so on. However, glass packaging containers also have some defects: they are serious, easy to be damaged, high transportation costs and poor secondary processing performance such as printing, resulting in a significant reduction in the amount of use. Nowadays, there was no drink made of glass containers on the shelves of large supermarkets. In places with low consumption power such as schools, small shops, canteens and small restaurants, Only then can we see the trace of low-cost glass bottled carbonated drinks, soybean milk and herbal tea.
