Aseptic packaging rising star

people who often pay attention to the milk and beverage shelves in supermarkets will find that in recent years, the packaging forms of products are diverse, and new packaging is emerging in endlessly. The earliest milk was bottled, and later it was mostly packed in bags and cups. Nowadays, "Tetra Pak", "fresh house", "Penguin bag", and "Tetra Pak pillow", these new packaging are becoming the mainstream of the market and are being adopted by more and more manufacturers. In fact, these new types of packaging have a unified title, which is "sterile packaging"

at present, in many parts of the world, sterile packaging has become one of the most closely related packaging forms to people's lives. As a rising star in the packaging industry, the wide application of sterile packaging in dairy production has become a new bright spot in the development of dairy industry

the aseptic packaging of milk is to adopt the instantaneous ultra-high temperature sterilization technology, and the sterilization and packaging of the packaged material (milk) will be completed at one time on a strictly closed production line. In the processing of dairy products, aseptic packaging technology has many advantages. First, it can keep the nutritional components of milk intact; Second, composite packaging materials and vacuum state can prevent products from light, gas, odor and microbial invasion, so that there is no need to add preservatives in milk, and there is no need to refrigerate during transportation and storage; Third, the shape of the aseptic packaging product is brick (or roof) shaped, and the packaging material is paper. The product has high space utilization rate, light weight, and the cost is not high. According to calculation, taking milk as an example, the cost of soft packaging is only one quarter of that of metal cans, and 97% of the total weight after filling is milk; Fourth, the packaging conforms to the current trend of environmental protection packaging. Because aseptic packaging has the above advantages, in addition to dairy products, this technology has been widely used in beverage, snack food, edible oil and other industries. 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 insiders

relevant experts believe that the overall level of China's packaging industry is many years behind that of some developed countries, but 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%. Some countries consume 100% per capita per year to develop new energy vehicles, taking into account the guidance of innovation and development. In China, 100billion packages (boxes) of sterile packaged drinks are available every year, and the per capita annual consumption is only more than 1 package, far below the world average of 20 packages per person per year. 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 has been introduced into China since the 1970s. In the 20 years of reform and opening up, many well-known foreign manufacturers have cooperated with China to build factories or sell 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. Another box of roof paper has begun to take shape in the late 1920s. At this time, the inner wall of the box 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 bag" with a capacity of 8 ounces came out. In 1986, the "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 extend the shelf life of products. In 1990, the "fresh-keeping house" with a hat plug roof carton 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 milk packaging in the field of aseptic packaging in China's dairy industry. Although the convergence phenomenon also exists in other industrial fields, it is particularly prominent in sterile milk 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. At present, some large-scale dairy enterprises, especially liquid milk production enterprises, have introduced Tetra Pak bricks to improve the quality and shelf life of their products, but the market response is not very good. Instead, some enterprises that have blazed new trails in aseptic packaging have achieved better results, such as Tetra Pak pillow and Penguin bag of Miaoshi Yipin milk, which are mainly promoted by Beijing Sanyuan this year, have far exceeded the brick packaging of similar products in sales. It can be seen that far sighted 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

at present, aseptic packaging technology is still developing. Even in countries with relatively developed industries, aseptic packaging technology is also a high-tech, and it also needs to strengthen investment for technological innovation. For packaging enterprises, we should strengthen cooperation with dairy products, beverages and other related enterprises. On the one hand, we should improve the design of packaging boxes that are widely used in various fields such as building wall insulation, aerospace, transportation, medical incubators, thermal insulation of various incubators and so on; On the other hand, we should expand the scope of use of sterile packaging, such as the further development of materials for sterile packaging, so as to facilitate the packaging of steamed beverages, beverages with particles and solid foods. Product manufacturing enterprises should pay close attention to the implementation of the project of recycling, separating and recycling waste packaging boxes, and recycling high-quality raw materials for recycling and treatment. In this regard, schools in Germany and Japan have set up milk carton recycling boxes to allow children to develop good habits since childhood. Timely recycling of discarded cartons for separation and utilization can reduce environmental pollution and benefit mankind

with the rapid development of China's economy, the aseptic packaging technology of food will be constantly updated. China's dairy enterprises should lose no time in researching and developing new products using aseptic packaging technology, so that aseptic packaging can become a booster for products to open the market
