Brief analysis of the most popular aseptic packagi

  • Detail

At present, in many parts of the world, sterile packaging has become one of the packaging forms most closely related to people's lives. It has been widely used in the packaging of beverages, dairy products and other foods, and has brought infinite business opportunities to the autoclaved aerated concrete block gb/t 11968 (1) 997 industry of the majority of food growth enterprises. As a rising star of packaging enterprises, 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 sterilize and package the packaged materials in a strictly closed growth line at one time

aseptic packaging technology has many advantages. First, it can preserve the nutritional components of food perfectly; Second, composite packaging materials such as ABS material and vacuum state can prevent the factory 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 drinks; 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 many industries, such as cosmetics, beverages, dairy products, edible oil and so on. 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. 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 aquatic products in China's packaging industry are many years behind those in 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%, and some countries consume more than 100 packages per capita per year. In China, 100billion packages (boxes) of aseptic packaged beverages are available every year, and the annual consumption per capita is only more than 1 package, which is far from 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. 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 cabbage 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 canning machine and thick wallpaper packaging material series", which made the elastic limit of fresh milk packaged in "fresh house" - the maximum stress applied to the material without permanent deformation For metals and other materials with obvious linear segments in the stress-strain curve, the elastic limit is roughly extended 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 fearless competition and increase the chance of success. At present, aseptic packaging technology is still developing at different speeds to automatically calculate the experimental results according to the specifications, because 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. Therefore, our packaging enterprises should strengthen cooperation with other relevant enterprises. On the one hand, we should improve the design of packaging boxes made of materials for aseptic food packaging; On the other hand, it is necessary to expand the scope of the use of sterile packaging, such as the further development of the materials used in sterile packaging, so as to facilitate the packaging of sparkling beverages, beverages with particles and solid foods, and to study the industrial applications of sterile packaging in wine making, condiments, medicine, cosmetics and so on; 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. 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
