Talking about tea beverage packaging

first, the tea beverage market is large

tea beverage is a dark horse with rapid growth in the beverage industry in recent years. It has developed more rapidly in Japan and Taiwan, and even in the world, the output of tea beverage is rising. Tea beverage, according to the definition described in the classification of GB soft drinks, should be the tea soup made by soaking tea in water, extracting, filtering, clarifying and other processes, or the products prepared by adding water, sugar, sour agent, edible essence, fruit juice or plant (grain) extract into the tea soup. There are also tea drinks, fruit juice tea drinks, fruit flavored tea drinks and other tea drinks. Tea soup beverage refers to products that directly fill tea soup (into concentrated liquid) into containers; Fruit juice tea beverage refers to the products prepared by adding water, raw fruit juice (or concentrated fruit juice), sugar solution, sour agent, etc. into the tea soup, and the content of raw fruit juice in the finished product is not less than 5.0% (m/v); Fruit flavored tea beverage refers to the products prepared by adding water to tea soup and eating essence, sugar liquid, sour agent, etc; Other tea drinks refer to products made by adding plant (grain) extract, sugar solution, sour agent, etc. to tea soup. In addition, according to the physical state of the product, it can be divided into liquid tea drinks and instant solid tea drinks. In liquid tea drinks, there are aerated (generally carbon dioxide) and non aerated

generally, from the perspective of consumers' consumption concept, tea drinks are often divided into green tea, black tea, oolong tea, scented tea, etc. according to the variety of tea. Some tea drinks are also named after oolong tea, Tuo tea, Longjing tea, Biluochun tea, kungfu tea and other tea that consumers like to drink. Some are also named after drinking, such as ice tea, warm tea and so on through the cooling or heating of vending machines. In a word, the product name, which is one of the important performance indicators of metal materials, can be determined according to the market cultivation and development needs of each production unit or enterprise (it must meet the general standard of GB food labeling)

in recent years, China's tea beverage market has developed rapidly, and the consumption of PET bottles for packaging has also increased rapidly. Especially in 2001 and 2002, hot filled PET bottles for tea drinks have become the fastest-growing variety of PET bottles, with an annual growth rate of more than 50%. Since tea drinks are required to be hot filled under the conditions of 85 鸆 -90 鸆, the temperature resistance of PET bottles for hot filling is required to be very high, generally reaching about 95 鸆, so its cost is higher than that of carbonated beverage packaging bottles

Second, the packaging form of tea drinks in China

the tea beverage packaging currently used in the world mainly includes glass bottles, metal cans, paper aluminum plastic composite brick type (1) when the motor produces abnormal noise: Tetra Pak packaging, polyester bottles, etc., while the tea beverage packaging mainly used in China includes metal three piece cans, Tetra Pak bags and polyester bottles (PET)

China's tea drinks are basically packaged in PET bottles. The tea is extracted at proper temperature and separated by high-speed centrifugation to obtain a clear and transparent tea beverage. After that, UHT (ultra-high temperature) is used for sterilization, and finally the bottled tea beverage is made by hot filling and sealing. PET packaging was first introduced by Pepsi Cola in the 1970s. It is cheap and has good transparency, air tightness and pressure resistance. In the early 1990s, Japan introduced heat-resistant PET production equipment, so that PET bottles can be hot filled. The biaxially stretched BOPP bottle produced by the injection extrusion drawing blowing process in China has surpassed PET packaging in terms of transparency, oxygen permeability, low temperature impact resistance and barrier property. It is a packaging material with market potential. In recent years, with the continuous improvement of production technology and equipment, PET bottles have increasingly shown their strong advantages

experts believe that compared with filling and glass bottles, PET bottles have the advantages of light weight, low price, convenient drinking, transparent bottle wall and so on, which make the products clear at a glance and attract attention. In addition, PET bottles are also easy to process. Various color masterbatches can be added to different products to give products different unique colors. For example, processing them into green can adjust consumer psychology, increase the stability of products, and prevent products from being oxidized. But the requirements for filling mineral water bottles are different from those for coke and tea drinks. Coke is a carbonated beverage, and PET bottles are required to prevent CO2 from seeping out and O2 from entering

pet bottled tea beverage packaging can be divided into three ways, namely, heat-resistant PET bottle hot filling technology, P school enterprise joint efforts to overcome the three difficulties, et bottle quasi high temperature filling technology and PET bottle sterile filling technology

three piece cans are tea beverage packaging used by most tea beverage manufacturers in China. The advantages of this package are strong processing adaptability, small loss, excellent barrier, and bright packaging and printing colors. However, due to the strict requirements on the internal coating of canned tea, the packaging cost is high, and the difficulty of environmental protection treatment, its development prospect has been affected to a certain extent, and the national industrial policy has not allowed a large number of promotion and use

paper aluminum plastic composite Tetra Pak is a popular packaging form in Taiwan, China Province, China, and has a considerable market in China. However, due to the difficulty of recycling this package, it is urgent to develop alternative packaging materials

with the wide popularity of tea drinks, tea beverage packaging containers will have a wide market. China's tea beverage packaging industry is still in its infancy. Therefore, vigorously researching and developing tea beverage packaging has a very broad development prospect
