With the development of national economy and the improvement of people's living standard, konglingxue has developed rapidly in China's beverage industry, especially beverage varieties. It has developed from a single glass bottled soda before the 1970s to the situation of the colorful carbonated beverage and natural drink. Beverage packaging industry also has a diversified trend, breaking the pattern of monopoly market of glass containers in the past. Metal, plastic, paper and other materials have been applied to beverage packaging. Metal easy to pull cans, PET bottles, PP bottles, Tetra Pak, Kangmei bags, roof bags, black and white film packaging powder appeared. Glass container packaging accounts for a large share of beer packaging, glass is a kind of packaging material with a long history, and glass bottle is also a traditional beverage packaging container in China. Glass container still plays an important role in beverage packaging when many kinds of packaging materials are entering the market. The main characteristics of glass packaging container are: non-toxic, tasteless, transparent, beautiful, good barrier, airtight, rich raw materials, low price, and can be used repeatedly. It has the advantages of heat resistance, pressure resistance and cleaning resistance, which can not only be sterilized at high temperature, but also stored at low temperature. Because of its many advantages, it has become the first choice for many beverage with high requirements for packaging containers, such as fruit tea and jujube juice. At present, a large number of glass bottles are still used in the production of domestic beer. In the field of beer packaging, glass bottles account for 36% of the market share. In the juice beverage packaging, the use of glass bottles is decreasing, with only 8.6 billion bottles in 2000, and 8.2 billion bottles in 2001. Glass bottles, like other packaging, are constantly being impacted by PET bottles. But many market people believe that PET bottles can not occupy all markets in some aspects, especially in the high-quality soft drinks and beer markets, there are still a lot of commodities using glass bottles as packaging containers, which also shows that in the development of beverage packaging, there is a trend of diversification. The "leading brands" in beverage packaging materials industry in China are the major beer producing countries. In 2000, the output has exceeded 21.4 million tons, ranking the second in the world, and has risen at the rate of 5 to 7% per year. Beer bottles can be recycled and reused, which is conducive to saving resources and environmental protection. At present, domestic beer packaging is still mainly glass containers. Metal cans are the only one used in the beverage packaging market. The metal cans are still widely used beverage packaging materials, which are divided into two cans and three cans. Two cans are mainly aluminum alloy plates, mainly used for the packaging of carbonated drinks; the three cans are tinned sheet steel (sheet iron), and are mostly used for beverage packaging without carbonation. As a beverage package, metal cans have the following advantages: first, it has excellent barrier performance. It can not only block gas, but also prevent light. This feature can make beverage have a long shelf life. Second, it has excellent mechanical properties, mainly in high temperature, humidity change, pressure, pest resistance and harmful substances. Third, it is not easy to damage, easy to carry, adapt to the fast-paced life of modern society. Fourth, the surface decoration is good, can stimulate consumption and promote sales. Fifth, it can be recycled and recycled. At present, the world produces 41billion metal cans every year, including 320billion beverage cans. However, for the Chinese market, the metal can packaging market has shown a trend of oversupply, but from the analysis of per capita consumption, there is still a large market space. The key to develop the market is to reduce the cost of metal cans. The technology of empty metal packaging in China is close to the international level. At present, we should vigorously promote the use of ultra thin sheet iron and aluminum, and carry out technical transformation and development of new products. In addition, we should also strive to improve the quality of the products and solve the most important quality problems of beverage cans, such as leaking cans, easy to open the cover and pull ring and easy to damage. PET bottle packaging, the world of tea beverage and beer Pet is the earliest, the largest production and the most widely used polyester product. The PET bottle produced by two-axis extended blow molding has good transparency, high gloss and glass appearance. However, pet is easy to cause gas penetration, especially for inflatable drinks such as beer, oxygen gas infiltration and carbon dioxide loss, which has obvious influence on flavor and taste.
