Current situation and trend of aseptic packaging i

  • Detail

Editor's note: with the continuous improvement of the consumption level of our people, the consumption of milk, fruit juice and other beverages will gradually increase in recent years. With this situation, aseptic packaging has become a new hot spot in food packaging. Chinese packaging enterprises should seize this opportunity to develop new products and seize the market

aseptic packaging is to use the instantaneous ultra-high temperature sterilization technology to complete the sterilization and packaging of the packaged materials in a strictly closed growth line at one time

aseptic packaging technology has many advantages: first, it can keep the nutritional components of food intact; Second, composite packaging materials and vacuum state can prevent products from light, gas, odor and microbial invasion, so that food does not need to add preservatives, and transportation and storage do not need refrigeration; Third, the shape of sterile packaging products is brick shaped, and the packaging materials are paper. The space utilization rate of products is high and the weight is light, so the cost is not high. According to calculations, taking beverages as an example, the cost of soft packaging is only a quarter of that of metal cans, and 97% of the total weight after filling is beverages; Fourth, the packaging conforms to the current trend of environmental protection packaging

due to the above advantages of sterile packaging, this technology has been widely used in beverage, dairy products, edible oil and other industries. In addition, due to the obvious advantages of aseptic packaging technology, this technology will gradually be applied in wine making, condiments, medicine, cosmetics and other industries for equipment manufacturers of recycled plastic granulators. Today, the vast majority of milk and more than half of fruit juices in developed countries use sterile packaging. This packaging technology is being promoted in China and is widely valued by people in the industry

relevant experts believe that the overall level of China's packaging industry is many years behind that of developed countries, but in his view, this gap also shows the growth potential of China's packaging industry. For products with aseptic packaging, in developed countries, such packaging has accounted for more than 65% of the whole beverage, with an average annual growth rate of 5% - 10%, and some countries consume more than 100 packages per capita per year. In China, 1billion packages (boxes) of aseptic packaged beverages are available every year, and the annual consumption per capita is far from reaching the level of 20 packages per person in the world. Therefore, aseptic packaging has great development potential in China. With the improvement of people's living standards, sterile packaging is gradually recognized by Chinese consumers

sterile packaging was introduced into China in the 1970s. During the 20 years of reform and opening up, many well-known foreign manufacturers have cooperated with China to build factories, or sold their products to China. A large number of food factories, beverage factories and dairy factories built with foreign technology and equipment have sprung up, which has promoted the development of aseptic packaging technology in China, and more and more production units are engaged in the development of aseptic packaging. According to preliminary statistics, at present, there are about 300 sets of sterile packaging equipment in China, with an annual production capacity of 1.5 million tons

The development of aseptic packaging technology is closely related to the development of aseptic packaging materials and the improvement of packaging design. The roof type carton has begun to take shape in the late 1920s. At this time, the inner wall of the carton is coated with wax. In the 1960s, this process was replaced by extrusion and plastic coating. By the 1970s, standard half pint cartons were born. Shortly afterwards, the "economic package" with a capacity of 8 ounces came out. In 1986, "thick wall bag" appeared. This kind of package can not only resist the acidity of fruit juice, but also retain the flavor of fruit juice and prolong the shelf life of products. In 1990, the hat plug roof carton "Qiaoxian house" was launched. In 1995, evergreen packaging machinery company, a subsidiary of American International Paper Company, developed a complete set of "evergreen canning machine and thick wallpaper packaging material series", which extended the shelf life of fresh milk packaged in "fresh house" to 28 days

there is a convergence of food packaging in the field of sterile packaging in China's food and packaging enterprises. Although the convergence phenomenon also exists in other industrial fields, it is particularly prominent in sterile food packaging. A certain form of packaging is good, but if everyone follows suit and follows up together, it will inevitably lead to similar products, no characteristics, and an increasingly fierce competition. Farsighted operators should have unique insight and choose novel and unique packaging forms for their products from a large number of packaging forms. This can avoid unnecessary competition and increase the chance of success

now, aseptic packaging technology is still developing, because even in countries with relatively developed industries, aseptic packaging technology is also a high-tech, and it also needs to strengthen investment in technological innovation. Therefore, our packaging enterprises should strengthen cooperation with other relevant enterprises. On the one hand, we should improve the design of packaging boxes used for sterile food packaging rather than the material of the panel itself; On the other hand, we should expand the application scope of sterile packaging, such as further developing the materials used for sterile packaging, so as to facilitate the packaging of steamy beverages, beverages with particles and solid foods, and studying the application of sterile packaging in wine making, condiments, medicine, cosmetics and other industries; We should also pay close attention to the implementation of the project of recycling, separating and recycling high-quality raw materials for waste beverages, and timely recycle waste cartons for separation and utilization, so as to reduce environmental pollution and benefit mankind

with the rapid development of China's economy, aseptic packaging technology for food will continue to improve, and the weight of a single car will have a great impact on the use experience. Our packaging enterprises should lose no time in researching and developing packaging products applied to aseptic packaging, so that aseptic packaging will become a new bright spot in the development of our packaging enterprises
