Development status of the four most popular bevera

The development status of the four major beverage packaging markets at home and abroad

with the development of the national economy and the increasing improvement of human living standards, China's beverage industry has developed rapidly, especially in soft drinks. It has developed from a single "soft drink" before the 1970s to a situation in which cola, Sprite, vegetable juice, fruit tea, green tea, black tea, mineral water and other carbonated beverages and natural beverages compete for beauty

1. Milk

because milk is easy to deteriorate, both long-term milk (Uh) and fresh-keeping milk put forward higher requirements for packaging. Packaging with long shelf life, good quality and good image is popular, and people have higher and higher requirements for the quality of milk packaging. In recent years, high-end milk packaging represented by Tetra Pak has grown rapidly in the south, while economic milk packaging is dominated in the north and central and western regions, and plastic bag packaging accounts for 70% of the whole liquid milk market. However, sterile pillows and sterile plastic bags produced by Tetra Pak are growing rapidly in the northern market, indicating that high-quality packaging is increasingly welcomed by the market. Tetra Pak pillow packaged fresh milk adopts ultra-high temperature instant sterilization composite packaging technology. At present, this technology has been widely used in developed countries for fresh milk packaging, and the normal temperature shelf life of fresh milk can reach 45 days. With this technology, high-quality fresh milk is instantly sterilized at an ultra-high temperature of up to 135 degrees, and then filled and sealed with six layers of paper aluminum plastic composite sterile packaging materials under sealed sterile conditions. All germs and microorganisms that affect the deterioration of milk will not contact it. Milk can be stored at room temperature for more than a month without adding preservatives

the roof box is beautifully printed and suitable for filling high-end products such as fresh milk, fancy milk, yogurt and lactic acid bacteria drinks with high nutritional value and fresh taste. The roof box is packaged with the words "shelf life of 10 days under ℃". Compared with Tetra Pak, the shelf life is relatively short, which limits its long-distance transportation. However, because the roof box is packaged in paper, the cost is low. In 1994, the international paper industry took the lead in introducing the roof box packaging into China's market. In the large plastic market, there are several 10 domestic important dairy production enterprises such as haiguangming, Beijing Sanyuan, Inner Mongolia Yili, Hangzhou Dingjin, etc. have successively cooperated with the international paper industry to jointly develop the roof box packaging market. In recent years, on the basis of the continuous improvement of the domestic cold chain system, the sales volume of roof box fresh-keeping packaging products in the market has increased significantly

2. Beer

the international beer packaging industry has developed rapidly in recent years by using heat-resistant polyester bottles (PET), especially the application of PET bottle coating technology (plasma technology), which is coated with a 0.21mm carbon layer inside. Its permeability is almost the same as that of glass. At the same time, it can withstand high-temperature sterilization treatment, so that its application range is expanded, and it is suitable for the packaging of hot filled tea drinks. In addition, polyethylene naphthalate (pen) new polyester bottles, which attracted the attention of the packaging industry, are entering the beer industry, causing a revolution in beer packaging (overcoming the beer bottle explosion). Because the molecular structure of pen and pet is similar, the naphthalene ring is used to replace the benzene ring, which makes pen and pet have excellent impermeability, UV linearity, good heat resistance and high temperature resistance (the thermal change temperature of amorphous pen is 100 ℃, while that of pet is only 70 ℃). As naphthalene is separated from coal tar, China has rich sources, and industrial production is about to be realized. Soon, pen entered the packaging field in large numbers, triggering another packaging revolution after pet. At present, a small amount of domestic imports, but the price is five times that of pet, which hinders the application of pen

the beer production and consumption in the United States have been the largest in the world for many years. Beer packaging containers are mainly metal (aluminum) cans and glass bottles, but the consumption of plastic (PET) bottles has increased rapidly in recent years, and glass bottle packaging has gradually increased in recent years. One of the important reasons to increase its consumption is the significant increase in the proportion of high-end beer

whether beer is packaged in glass or plastic. The current situation is that the process of plastic bottles has overcome almost all technical problems, and the shelf life is enough to meet the requirements of sales. Now the key to the problem is whether consumers recognize it. China is the second largest beverage market in the world, and the demand for beer packaging will be huge. Packaging machinery manufacturers are ready to provide beer PET plastic bottling system with the latest technology at any time

3. Fruit juice

Australian researchers have successfully developed a fruit juice packaging cup with high shielding performance, which has been used by fruit processors with remarkable results. This kind of packaging cup, mainly packed with fruit juice and jelly, has been sold in supermarkets in large quantities, and its shelf life is 18 months. The cup is packed in a 3-layer coextrusion structure, including a layer of PP, a layer of EVOH and a layer of bonding layer. The outer PP can absorb ultraviolet rays, and the transparent packaging cup has high shielding performance, which can prevent fruit juice and jelly from changing color under light. The cup adopts the packaging machine 'target'=_ Blank> transparent film cover, which can be hot filled or cooked. Take monochrome or two-color gravure printing on the hot formed deep drawing cup, and put it on the 'target' of the packaging machine=_ Blank> the transparent film cover and the cup body can be locally printed. The cup is wrapped in a paper sleeve and can be printed in 6 colors. With a diameter of 98.4mm and a depth of 105mm, it replaces some metal cans to pack fruit juice and jelly, and has a wide application prospect

a Wisconsin company successfully developed a full sealing device for fruit juice filling, which can ensure that fruit juice is free from the adverse effects of hot gas and steam from the filling line to the packaging process. When the filling temperature is lower than 250 F, it can still meet the requirements of killing bacteria, while maintaining the stability of filling. The temperature below 250 f can ensure that the side wall of filled plastic bottles, especially HDPE bottles, will not collapse during vertical filling. Because the filling and filling is in a fully closed state, so as to maintain the acid of fruit juice, such as the pH value of citric acid is at a low point, which is suitable for packaging low acid beverages. The HDPE bottle is made by CO extrusion blow molding, and its filling and filling speed is 32 ounces, 200 bottles/min. The bottle making equipment adopts the foiler2450 pillar machine, with a capping device, and adopts the membrane parts of a fully sealed box to ensure sealing. The power consumption of this equipment is 4kw

4. Tea beverage

at present, modern technology has broken through many problems in the cultivation of tea beverage production technology professionals, and packaging and storage have become the key that manufacturers must pay attention to. At present, the world's popular tea beverage packaging includes glass bottles, metal cans, paper aluminum plastic composite brick Tetra Pak, polyester bottles (PET pen), etc., while metal three piece cans, Tetra Pak and PET bottles are widely used in China

most domestic tea beverage manufacturers have set up three piece can production lines. The advantages of metal cans are less processing adaptability loss, excellent barrier, and bright packaging and printing colors. However, its production cost is high, and the requirements for the internal coating are more stringent, because canned tea often has problems due to the uneven coating in the can, and it does not meet the environmental protection requirements when it is discarded. In addition, due to the limitations of resources, markets, funds, technical conditions and other restrictions, the national industrial policy does not allow a large number of promotion, However, there is still a certain demand in large and medium-sized cities. Paper/aluminum/plastic composite Tetra Pak is a popular packaging form in Taiwan Province at present. Most Taiwanese businessmen also brought this kind of packaging when they came to invest in China. However, due to the difficulty of recycling this packaging, it is necessary to develop alternative packaging materials

pet is a pressure resistant polyester material, which meets the packaging materials of various products on the market. It is cheap and has good transparency, air tightness and pressure strength. China's Shanghai three power supply: 220V ± 10% Deli Merlin company also used PET bottles produced by this equipment when it launched bottled oolong tea drinks. As the Chinese people pay special attention to tea drinks, when introducing new tea beverage products, manufacturers must not only fully consider the tea drinking habits, flavors and product characteristics of various places, but also shape the personalized packaging of tea drinks that is different from ordinary soft drinks, especially the polyester packaging with excellent performance, beautiful appearance, economy and convenience

the packaging containers of Japanese tea drinks include pet bottles, aluminum cans, tin cans, glass bottles, paper containers and other types. However, PET bottles have become the first choice and the most important packaging container for Japanese tea drinks. Tea drinks packaged with pet account for 67.1% of all tea drinks in Japan
