  • Detail

The space and measures for the sustainable development of aseptic fresh-keeping packaging aseptic packaging is a big industry aseptic packaging refers to a packaging method in which products, packaging containers, materials or packaging aids are filled and sealed in a sterile environment after sterilization. Aseptic packaging was born in the 1940s, applied in the 1960s and developed in the 1970s. It can keep the packaged products fresh for half a year or more without deterioration under normal temperature without adding preservatives. It also has the advantages of low energy consumption, less packaging materials, low manufacturing cost accounting, high packaging efficiency, good economic benefits, light quality, easy long-distance transportation and sales, and recyclable waste packaging

at present, the types of aseptic packaging have developed from single composite paper packaging to plastic bottles, plastic cups, plastic composite bags, glass bottles and other types, but still mainly composite cartons. There are more and more aseptic packaging styles. Taking composite carton packaging as an example, there are brick shaped, house shaped, pillow shaped, triangle shaped, axe shaped, square cylindrical, cylindrical and so on. A mouth and an anti-theft cover can be added in addition to cannula for drinking. The packaging capacity ranges from 50ml to 1500ml, and the large bag packaging capacity ranges from a few liters to dozens of liters, 100 liters and even more. Aseptic packaging is more and more widely used, from packaging liquid to fluid, semi fluid and paste; From general fruit juice to milk, tea, vegetable juice, soup, wine, water, liquid medicine, etc

it is reported that aseptic packaging has accounted for more than 65% of liquid food packaging in foreign developed countries, with an annual growth rate of more than 5%. Aseptic packaging in cartons alone consumes more than 100 billion pieces worldwide every year, which is equivalent to more than 1 million tons of composite paper only based on the calculation of 250 ml packaging. The manufacturing of these composite materials requires more than 700000 tons of paperboard, more than 100000 tons of plastic and more than 50000 tons of aluminum foil. The sales value of these more than 100 billion cartons is 5billion US dollars based on the 250 ml of 0.05 US dollars, and the packaged products and outer packaging are at least more than 20billion US dollars. Moreover, many of the more than 100 billion cartons are more than 500 ml. If we add other plastic cups, plastic bottles, small plastic bags and aseptic packaging of Panasonic exchange servo electromechanical plastic bags, as well as related packaging machinery and packaging auxiliary equipment, it will be a big industry

as an industry or field, aseptic packaging includes packaging technology, packaging materials and packaging containers, packaging auxiliary equipment and packaging machinery, packaging auxiliary materials and packaging scientific research, education, packaging engineering, as well as related industries and disciplines

development of aseptic fresh-keeping packaging in China

after the initial and development stages, aseptic fresh-keeping packaging in China has entered a stable transition stage. Since 1996, affected by the national macro-control of economy, tightening of monetary policy, reduction of fixed asset investment, deepening reform of state-owned enterprises, and temporary decline of consumption level, Cedric Kennedy, a professional manufacturer of sterile fresh-keeping packaging in China, has gradually slowed down the exhibition of recycling waste plastics into 3D printing materials. Some of the original enterprises have insufficient construction, and the number of large new factories has decreased significantly. Those who want to import are cautious, Instead, township enterprises, private enterprises, partnership enterprises or sole proprietorship enterprises are starting. Limited to their financial strength and business scale, most of these enterprises choose domestic equipment, use domestic packaging materials or containers, and produce products of comparable quality and appropriate price to supply the market, supplementing the gap of insufficient operation of the original imported equipment. According to incomplete statistics, there are more than 15 domestic aseptic packaging production lines and complete sets of equipment with small output sold annually in China, and the output of aseptic packaging products in China remains basically unchanged, sometimes rising slightly. For this situation, people who do not know the details think that the development of aseptic packaging in China has come to an end, or mistakenly believe that composite paper packaging is out of date. In fact, it is not. The author believes that this is the momentum of the transition period. According to the investigation, the aseptic packaging industry in China has great potential

the space for sustainable development of aseptic fresh-keeping packaging in China in the future

China has a large population, a vast territory, rich products, and is located in the tropical and subtropical regions. With the deepening of reform and opening up and the further implementation of the policy of enriching the people, the people's living standards have been continuously improved, the people's consumption concept has been constantly updated, the tourism industry has become increasingly prosperous. With China's entry into the WTO, the country will be fully open, all aspects will gradually be in line with international standards, Sino foreign joint ventures and cooperation will be further strengthened, and the economy is increasingly active. All these provide a broad development space for China's sterile fresh-keeping packaging industry

1 the development level of aseptic fresh-keeping packaging in China is still far behind the world level

-- Taking carton packaging as an example, the annual per capita consumption of aseptic packaging in some countries has reached more than 100 packages, and the world's per capita is also close to 20 packages, while China's per capita annual consumption is only more than 1 package

-- proportion of aseptic packaging and similar packaging aseptic packaging in developed countries has accounted for more than 65% of the packaging of similar products, and some have exceeded 70%, while China only accounts for 5%

-- the development rate of aseptic packaging in developed countries has increased by more than 5% annually on average, with a maximum of more than 8%, while China has experienced a process of stagnation after development. Many application channels are waiting for us to develop

-- in the medium and long-term development goal of dairy industry formulated by the Ministry of agriculture of China, at the end of the tenth five year plan, the per capita share of dairy products will reach 10kg, and the total output will reach 13.5 million tons; By 2030, the per capita share of milk will reach 25 kg and the total output will reach 42.5 million tons. Due to the great regional differences in China, the distribution of milk production and marketing areas is extremely unreasonable. The main production areas do not sell much, and the main sales areas do not produce milk or produce less milk. To change this unreasonable situation, we must rely on reasonable packaging - aseptic fresh-keeping packaging to solve the problem of long-distance transportation and marketing. According to the world development trend, in the future, dairy products should be changed from milk powder to liquid milk, which can save energy, improve nutritional value and facilitate eating. Aseptic fresh-keeping packaging is adopted for 25% of dairy products. By the end of the tenth five year plan, 6.75 billion aseptic fresh-keeping packaging containers (500ml) are required every year. Each container is calculated at 0.5 yuan, with a value of 3.375 billion yuan. By 2030, more than 20billion containers (calculated by 500ml) will be needed every year, worth more than 10billion yuan

-- fruit juice beverage and other beverage industries according to the announcement of China Beverage Industry Association, China's per capita beverage consumption is only one-fifth of the world average. There is great potential for output development, and many products need to be developed. It is expected that the total output of beverages will reach 14million tons in 2000. During the Tenth Five Year Plan period, it will increase at an average annual rate of 10%. In 2005, it will reach 22.6 million tons. From 2005 to 2015, it will increase at an average annual rate of 5%. In 2015, it will reach 37million tons. Based on this, taking 20% of them as aseptic packaging, 9.04 billion aseptic packaging containers (based on an average of 500ml) will be required every year from 2005, and 14.8 billion aseptic packaging containers (based on an average of 500ml) will be required every year from 2015

-- vegetable juice processing industry at present, the aseptic packaging of vegetable juice processing in China is almost blank. In 1997, the planting area of vegetables in China reached 11288000 hectares, the output of vegetables was 345million tons, and the per capita share of vegetables was 279 kg, greatly exceeding the world per capita level of 102 kg. With the progress of society, the development of science and technology, people's pursuit of health and the renewal of consumption concept, relevant departments and experts predict that in the next 5-10 years, China's vegetable juice as beverage or seasoning will develop to a certain extent. The best packaging for the few products of this kind of waste plastic recycling plant will be aseptic packaging. Because it can not only effectively maintain the original nutritional components, but also make the products not change color, taste, deterioration and suitable for long-term storage

-- traditional Chinese medicine preparation industry China is a big country in the species, collection and use of traditional Chinese medicine and herbal medicine. Traditional Chinese medicine and herbal medicine are not only famous in China since ancient times, with a long history and tradition, but also well-known internationally. They are a valuable pharmaceutical wealth industry. With the progress of science and technology, the improvement of processing level and the acceleration of people's pace of life, the traditional home-based traditional Chinese medicine is not only labor-consuming, time-consuming and energy consuming, but also inconvenient to take. In the future, traditional Chinese medicine and herbal medicine should be taken by pharmaceutical factories and hospitals according to the traditional fixed prescriptions, test prescriptions, addition and subtraction prescriptions and compound prescriptions. Different capacities should be set according to different ages, packed in sterile packaging, and distributed to wholesale markets, retailers, hospital pharmacies and folk pharmacies. Doctors can list the prescription of finished Chinese medicine aqua for patients according to their conditions, General patients can also buy Aqua Chinese patent medicine in pharmacies according to their own conditions. At present, only a few domestic enterprises produce health drinks such as aseptic packaged cool tea, and no one has developed aseptic packaged Aqua Chinese patent medicine. The development of this new field will bring infinite business opportunities to the sterile packaging industry and bring great convenience and good news to patients. In addition, aseptic fresh-keeping packaging for tea and wine is also waiting for us to develop. 3. Bring new opportunities to relevant industries and departments and promote new economic growth

-- existing enterprises in the production of packaging materials and packaging containers can obtain full production. Where aseptic and fresh-keeping packaging enterprises in the food and pharmaceutical industries are concentrated, additional packaging material factories and packaging container factories can be built to achieve nearby supply

-- the production of packaging raw materials, such as cardboard and special resins for composite materials, are still imported. Strong paper mills and plastic chemical plants can produce special cardboard and modified plastic resin to increase the added value of products

-- the machinery manufacturing industry can produce various aseptic packaging machines, fresh-keeping packaging machines, complete sets of equipment for pre-treatment and supporting equipment for post-treatment

-- the food and beverage industry benefited the most from this industry. The company realized a sales revenue of 12billion yuan and a profit of 1.24 billion yuan. Through the use of sterile fresh-keeping packaging, it improved the product grade, extended the shelf life, and was suitable for long-distance transportation and sales, thus increasing the output, sales volume and product added value.
