The hottest sterile packaging expands the developm

  • Detail

At present, in many parts of the world, sterile packaging has become one of the packaging forms closely related to people's lives, and the proportion of downstream deep processing links has increased. It has been widely used in the packaging of beverages, dairy products and other foods, and has brought unlimited business opportunities to a wide range of food production enterprises. As a rising star of packaging products, sterile packaging is becoming a new bright spot in the development of packaging industry

aseptic packaging is to use instant ultra-high temperature sterilization technology to complete the sterilization and packaging of packaged materials at one time on a strictly closed production line. Aseptic packaging technology has many advantages. First, it can preserve the ingredients with good nutritional properties; 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 generally brick shaped, and the raw materials are paper. The space utilization rate of products is high and the weight is light, so the cost is not high. The cost of soft packaging for beverages 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 trend of environmental protection packaging. Due to the above advantages of aseptic packaging, this technology has been applied in the packaging of food, beverages, dairy products, edible oil, wine, condiments, medicine, cosmetics and other products. At present, the vast majority of milk and more than half of fruit juice in developed countries use sterile packaging. This packaging technology is being promoted in China and is favored by insiders

relevant experts believe that the overall level of China's packaging industry still lags far behind that of some developed countries, but this also shows the potential for the development of China's packaging industry. The beverage products packaged with aseptic packaging technology have accounted for more than 65% of the whole beverage in developed countries, with an average annual growth rate of 5% - 10%, and some countries consume more than 100 packages per capita per year. In China, the per capita annual consumption is only more than 1 package, far below the level of 20 packages per capita in the world. With the improvement of people's living standards, sterile packaging is gradually recognized by Chinese consumers

aseptic packaging was introduced into China in the 1970s. After 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. Roof type cartons began to take shape in the late 1920s, when the inner wall of cartons was 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 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 filling machine and thick wallpaper packaging material series", send "The shelf life of fresh milk packaged in fresh house has been extended to 28 days.

there is a convergence of food packaging in the field of sterile packaging among China's food packaging enterprises. Although the convergence 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 is bound to cause product similarities, lose characteristics, and form more and more 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. At present, 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, packaging enterprises should strengthen cooperation with other relevant enterprises, on the one hand, improve the aseptic food packaging materials and packaging shape design; On the other hand, it is necessary to expand the scope of use of sterile packaging, such as the further development of sterile packaging materials if they flow out in line, so as to facilitate the packaging of aerated beverages, beverages with particles and solid foods, and expand the application of sterile packaging in wine making, condiments, medicine, cosmetics, etc; We should also pay close attention to the implementation of the project of recycling, separating and recycling high-quality raw materials of waste beverage packaging, and timely recycle waste cartons for separation and utilization, so as to reduce environmental pollution. 3. With the rapid development of China's economy, the aseptic packaging technology of food will continue to improve. Packaging enterprises should lose no time to research and develop new products of aseptic packaging and expand the development space of aseptic packaging. (Zhichi)
