The founding process of Tetra Pak
Dr., founder of Tetra Pak.
Ruben Rausing) was born on June 17, 1895 in Raus, Sweden, next to Helsingborg. In 1918, he graduated from Stockholm School of Economics. In 1920, he received a master’s degree in science from Columbia University in New York. While studying in the United States, Rubin Lushing first came into contact with the self-help store (“Self Service” Store). At that time, he foresaw that this concept would be adopted in Europe, thus driving the demand for packaged food with high convenience. In 1929, the decline in the stock market on Wall Street triggered a global recession, and Rubin Loussin and Erik Akerlund set up the country’s first professional packaging factory in Sweden. The company, Akerlund Rausing, later became one of the largest packaging factories in Europe. At that time, the factory was mainly making flour bags to improve the situation of flour wasted during bulk transportation at that time. During the second World War, a large number of rural people poured into the cities, and people lived far away from food production, so they paid more attention to food distribution. At that time, consumers had to return the glass bottles of milk to the manufacturers for re-use. Rubin Loussin has long known that this traditional way of food distribution will affect the sales of bottled milk in self-service stores. In view of this, Rubin Loussin called on a group of energetic people and convinced them that it was necessary to create new packaging technology, so he studied a practical and disposable milk carton. This kind of packaging later brought about major reforms in the dairy industry, bringing safe and easy-to-carry packaging to consumers.
Tetra Pak: a professional company
In 1951, Akerlund Rausing set up a subsidiary in Lund, namely Tetra Pak. In 1952, the first Tetra Pak bag machine to make tetragonal boxes was officially put into production. In 1965, with the exception of Rubin Loussin, who retained ownership of Tetra Pak, companies owned by the Akerlund Rausing and Rausing families were sold. As a result, Tetra Pak has more resources to focus on manufacturing and supplying complete food packaging systems, materials and distribution systems. From then to 1991, Tetra Pak has been a company specializing in paper packaging.
Enter a new mileage
In 1991, Tetra Pak reached a new milestone in its history. At that time, Tetra Pak acquired Alfa-Laval, the world’s largest manufacturer of food processing and agricultural equipment. The company was reorganized in 1992 and the Tetra Laval Group was established in January 1993. At present, the group is made up of three independent companies, each engaged in different professional businesses. When Alfa Laval Food Engineering was integrated into Tetra Pak, we acquired the appropriate equipment and expertise to expand the liquid food process and manufacturing business, so Tetra Pak is currently the only supplier in the world that can provide a full range of food packaging, process and distribution systems. Tetra Pak is a company that provides complete solutions for food processing and packaging. For 50 years, Tetra Pak has always positioned itself as an active participant in the food industry. Security and innovation are two pillars that complement each other and jointly promote the growth of Tetra Pak. Today, Tetra Pak has 57 sales companies worldwide and is licensed to operate 48 packaging material factories and 12 packaging machine assembly plants. In 2008, Tetra Pak had sales of about 8.825 billion euros and employees of 21640. Tetra Pak products are sold in more than 165 markets. In 2006, the company produced 129.7 billion packages, providing 67.4 billion litres of liquid food products to consumers around the world. Tetra Pak’s changes to China include its help to dairy giants. Yili is a key customer of Tetra Pak in China. It used to be a small company serving the area around Hohhot. Tetra Pak used its advanced technology to preserve fresh dairy products to help Yili successfully transform from a regional enterprise into a domestic dairy giant. Tetra Pak has invested a total of 200 million US dollars since it entered the Chinese market in 1972. At present, Tetra Pak, headquartered in Shanghai, has a strategic network in China, including packaging raw material factories and processing centers, and has joint venture or wholly owned factories in Beijing, Shanghai, Kunshan, Foshan and other places. Process guarantee Innovation, which has more than 5000 technology patents and 2800 innovation giants under development and application, has never lacked the passion for innovation. It strives to perfect the combination of invention and practice, so that the technical capability of innovation has the feasibility of commercialization, and there are a series of ideas and processes to ensure the continuous flow of innovation. How does Tetra Pak guarantee innovation from the “process”? Is to promote R & D affairs to the level of senior management of the company, and examine R & D work from the perspective of customers. This means adopting a cross-disciplinary way of thinking and breaking the rules within the company. Tetra Pak distributes its R & D centers in many countries to bring technological innovation closer to the market. Moreover, process orientation is very important in Tetra Pak R & D, a globally dispersed organization. The secret of Tetra Pak’s innovation is to deeply understand and constantly meet the needs of users, and unremittingly create interesting products. Tetra Pak has a team of more than 100 people around the world, they are distributed in different places, the team’s job is to sense the market. “it’s like a company detector or sensor. It is not enough to ask customers what they need. We need to have a first-hand perception of the market so that we can foresee the needs of the market, and we must know these trends before our customers make a request. ” Dr. GE Ruoshan, executive vice president of Tetra Pak, explains innovation in this way. Although Tetra Pak can enter the global top 500 in China, Tetra Pak, as a family business, is not interested in ranking and insists on serving customers. Tetra Pak China believes in the business philosophy of “growing together with Chinese customers” and adopts the model of omni-directional and in-depth integration of resources to serve customers. The low-key Swedish company has increased its joint image promotion with customers since 2005, and these advertisements, which are mainly borne by Tetra Pak, still focus on the image of customers. In Tetra Pak’s view, these new packaging not only strategically expand its own product line, but also bring value-added services to customers. Since we insist on putting customers first, Tetra Pak also has the same characteristics in terms of employing people. Tetra Pak, which has no rules and regulations, abandons the idea of “one radish, one pit”. As long as customers need it, the company needs it, and employees have the ability and conditions, they can do other things in the “pit”. In China, more and more enterprises have become Tetra Pak’s customers. And with Yili, Mengniu, Guangming, Wa, Huiyuan. With the rapid development of Juer and other brands, Tetra Pak has attracted more and more attention as an integrated service provider such as packaging equipment and materials to help them create good results. Tetra Pillow, Tetra Pak bricks and other products are also regarded by consumers as the guarantee of beverage safety and nutrition. Since entering China in 1972, Tetra Pak has provided thousands of filling lines for local milk and beverage customers. More than 30 years of experience and continuous investment have finally paid off in the past few years. People around the world consume 14 billion litres of water, milk, juice and other liquid foods every day. Over the years, Tetra Pak has been committed to the mission of ensuring that safe food is available everywhere, developing packaging that preserves the original taste and nutritional value of products, so that a large number of liquid foods can be well distributed to consumers. Tetra Pak has a wide variety of products, providing no less than 12 packaging systems for pasteurized and aseptic packaging products, which are basically divided into paper packaging and plastic packaging. Tetra Pak is a world leader in the field of room temperature carton packaging business. The products offered include Tetra Pak Brick, Tetra Pillow, Tetra Pillow, Tetra Lowe and Tetra Pillar and so on. The aseptic Tetra Pillow packaging system is an economical solution designed for emerging markets. At the same time, Tetra Pak’s aseptic processing equipment and distribution equipment are also popular. Today, there are numerous products that can be packaged in Tetra Pak packaging, such as ice cream, cheese, anhydrous food, fruits, vegetables and pet food.

Have a foothold in the long run and take root in the mainland
As early as 1972, Tetra Pak came to the fore at an exhibition in China. With the rapid development of the food industry, Tetra Pak’s first filling machine was put into use in Guangzhou in 1979. 250ml carton chrysanthemum tea produced by this technology was immediately welcomed by the majority of consumers. From China’s reform and opening up to China’s accession to the World Trade Organization, Tetra Pak has been close to the needs of the domestic liquid food market and actively introduced the latest food and beverage packaging technology. Since 1972, Tetra Pak’s cumulative investment in the Chinese market has reached 2.6 billion yuan. At present, Tetra Pak has set up 10 offices in major cities such as Shanghai, Beijing and Hong Kong, set up wholly owned factories in Kunshan, and formed two joint ventures in Beijing and Foshan, with a total of more than 1200 employees. distribution network all over the country. In recent years, with the rapid development of China’s dairy industry, Tetra Pak products have also been widely recognized by the Chinese market. In September 2004, Tetra Pak China officially opened a new packaging plant with an investment of 620 million yuan in Beijing, with an additional investment of 30 million euros in August 2006, doubling its annual production capacity from 8 billion packages to 16 billion packages. In March 2007, Tetra Pak announced that it would invest more than 600 million yuan to build a world-class packaging factory in Hohhot. With the great increase in total production capacity in China, Tetra Pak will be able to cope with the possible growth of market demand in the Chinese market in the next five years, which is also sufficient proof of Tetra Pak’s confidence in the Chinese market. While continuously increasing investment, Tetra Pak has also introduced the world’s most advanced packaging technology and concepts into the Chinese market. In October 2002, Tetra Pak established a design center in Foshan to develop novel packaging designs and concepts. In early 2003, Tetra Pak Shanghai processing equipment system Center was established, which mainly provides pre-processing equipment for customers engaged in liquid food production. Tetra Pak Packaging (Kunshan) Co., Ltd. covers an area of 6100 square meters in a large warehouse, its advanced warehousing management can match Tetra Pak’s rapidly expanding production capacity. The new factory in Beijing has introduced the most advanced production line equipment and related technical means in the world, such as multi-color sleeve printing technology, printing image computer automatic monitoring system and automatic quality tracking and testing system in the whole production process. Static paper feeding and so on. In February 2007, Tetra Pak announced the formal establishment of Tetra Pak Global’s most advanced design conversion center in Beijing, which will rely on Tetra Pak’s global resource advantages and Tetra Pak’s technology and equipment advantages in flexographic dot printing. to provide Chinese customers with innovative technology, sound management and efficient processes to provide more quality services. Tetra Pak has always focused on its long-term development in China, committed to “meeting the diversified needs of the Chinese market through diversified products”, and continues to introduce advanced technology and equipment and perfect supporting services into China. Actively promote the process of localization of production services, playing an important role in the field of liquid food packaging in China.
Tetra Pak China milestone
The first Tetra Pak filling machine was put into use in Guangzhou in 1979. Tetra Pak China Co., Ltd. was established in Hong Kong in 1985. Beijing Chartered Packaging material Factory was put into production in 1987. Foshan Chartered Packaging material Factory was put into production in 1991. Representative offices were set up in Shanghai and Beijing in 1993. Representative offices were set up in Guangzhou in 1994. Set up regional offices in Chengdu and Xiamen with Beijing Pulp and Paper Experimental Factory and Foshan Huaxin Packaging Co., Ltd. respectively set up joint venture packaging material production plants in Beijing and Foshan in 1995 set up regional offices in Harbin in 1996 Kunshan Packaging material production Plant officially opened Foshan Packaging material production Plant and obtained ISO14001 certification Beijing Packaging material Factory obtains ISO90021 Certification in 1998 Regional offices in Nanjing and Xi’an set up ISO14001 certification in Kunshan and Beijing Packaging material production plants in 1999 Kunshan processing equipment Center opened in 2000 Tetra Pak Chinese management moved to Shanghai joint venture Tetra Lok Xin (Foshan) Packaging Co., Ltd. to establish a 2002 joint venture Tetra Pak Packaging (Beijing) Ltd. established in 2003 Shanghai Pudong processing equipment system Center was established in 2004 the second joint venture factory in Beijing was officially launched on September 23, 2005 Tetra Pak 1000 filling machine settled in Hangzhou Weilijia Food Co., Ltd. The new emblem of protecting quality was officially unveiled in 2006 Tetra Pak Packaging (Beijing) Co., Ltd. increased its capital by 30 million euros and doubled its production capacity. In 2007, Tetra Pak, the world’s most advanced design conversion center, was established in Beijing by Tetra Pak Packaging (Hohhot) Co., Ltd. to establish ultra-high temperature sterilization technology: Dr. Rubin Loxin, the founder of Tetra Pak, who opened the national market for dairy enterprises, once said: “the savings brought by packaging should exceed its costs.” Packaging makes a great contribution to global food safety, nutrition and human health. without packaging, more than 50% of liquid food will be spoiled or contaminated and cannot be delivered to consumers. Since Baxter invented pasteurization in the mid-19th century, it has been regarded as an important breakthrough in food science. With the emergence of aseptic processing technology and packaging in the 1940s, it brought another revolution to food science. In 1989, instantaneous ultra-high temperature aseptic processing technology was praised by the American Institute of Food Technology as the most important achievement in food science in the past 50 years. Tetra Pak is a pioneer in the field of aseptic packaging and processing technology. Instantaneous ultra-high temperature sterilization (UHT) means that the product is heated to a high temperature (such as milk to 137C) in a closed system and lasts for only 4 seconds, then quickly cools to room temperature. This process, combined with advanced aseptic packaging technology, can effectively preserve the nutrition and taste of dairy products or drinks. At the same time, since the process from the forming of the package to the filling of the product is carried out in the aseptic area sealed by the same machine, it ensures safety, hygiene and space saving. Aseptic processing technology and packaging enable products to have a longer shelf life at room temperature, which helps to transport high-quality liquid food to faraway places at a lower cost. It not only makes the production process of food more reasonable, but also shortens the storage period, and provides consumers with more convenience and choice. The special feature of China’s dairy market is to transport a large number of fresh and high-quality milk produced in North China, such as Inner Mongolia, to the broader South China market. Tetra Pak provides a technical solution suitable for long-distance transportation, easy storage and long-term preservation. Tetra Pak’s packaging is deeply trusted by customers and consumers because it ensures the safety, nutrition and freshness of food, and brings great convenience to the storage and transportation of businesses and consumers. High-quality products plus a full range of services, so that customers feel good value for money, for customer product safety and profitability to provide a strong guarantee. Environmental protection in recent years, with the improvement of our living standards and the continuous enhancement of health awareness, the demand for milk, juice and other drinks is increasing, resulting in more and more abandoned Tetra Pak bags. However, because consumers do not know that Tetra Pak bags can be recycled, they often throw waste bags away casually. In fact, they are completely “misplaced resources”. Through the treatment and processing of professional manufacturers, discarded Tetra Pak bags can produce a large number of household articles and industrial materials such as recycled paper, floors, garbage cans, clothes hangers, table tennis rackets and trays, which is not only beneficial to environmental protection, but also produces good economic benefits. Tetra Pak is packaged with six layers of composite paper, of which about 75% is made of high quality long fiber pulp, which is undoubtedly a high quality raw material for recycled paper. In order to protect the human living environment and with a high sense of social responsibility, Tetra Pak actively helps to develop the recycling technology of Tetra Pak bags. At present, a new waste composite paper packaging recycling industry chain is gradually taking shape from south to north, and professional recycling plants have been established in Shanghai, Hangzhou, Shenzhen and other places. Recovery and reuse technologies are mainly divided into three categories: 1. Hydraulic recycled pulp technology: the pulp in Tetra Pak bag is separated to produce recycled paper, while the plastic and aluminum components in Tetra Pak bag are extruded into granules to become a good raw material for the production of plastic products. two。 Plastic and wood technology: Tetra Pak bag itself contains high-quality paper fiber, aluminum and plastic, crushing and extruding them to produce plastic and wood products with the best use and low cost. Indoor furniture, outdoor gardening facilities, industrial pallets and so on are all popular and well received. 3. Color music board technology: the discarded Tetra Pak bag is directly crushed and hot-pressed to make a color music board. The color music board can be made into a variety of products, especially the fruit case, which is beautiful, durable and low cost. However, the common problem faced by recycling manufacturers is the lack of enough waste Tetra Pak raw materials, and the production line is still in a state of “insufficient food”. Therefore, to publicize Tetra Pak bag recycling knowledge, cultivate recycling habits and establish a convenient recycling system is not only an urgent problem to be solved, but also a long process, which requires the joint efforts of manufacturers and society. Therefore, in line with the sense of social responsibility to protect the human environment, Tetra Pak and the Youth Daily jointly organized a public welfare activity entitled “Recycling Tetra Pak bags and Happy Environmental Protection” in May 2005, calling on consumers to actively participate in Tetra Pak bag recycling, establish good recycling habits, and jointly contribute to the cause of environmental protection. Since September 2006, Tetra Pak supported Beijing Joint Open Source Renewable Resources Recycling Co., Ltd. to train community scavengers and carry out recycling work in more than 100 communities with the help of a regularized and large-scale recycling network. Within a short period of four months, the amount of recycling has rapidly risen to more than 50 tons.
What kind of equipment is needed for the milk production line?
The milk production line mainly produces sterilized fresh milk, pasteurized milk, reduced milk, peanut milk, student milk and so on. The complete fresh milk production line mainly includes: milk receiving system, blending system, milk purification and standardization system, homogenized degassing system, sterilization system, filling system and so on.
Full set of fresh milk equipment:
Storage tank-beverage pump-milk tank-hot and cold cylinder-cream separator-degasser-blending cylinder-homogenizer-ultra-high temperature sterilizer-plate heat exchanger-seed tank-fermentation tank-sterilizer-automatic filling machine.

Milk is a paradise for microbial activity. According to the experiment, the newly milked milk was not treated at room temperature, and the content of microorganisms per milliliter of milk soared from 114000 per milliliter after 12 hours to 1.3 million per milliliter in 24 hours. That’s why milk spoils easily. Therefore, the disinfection and preservation technology of milk is very important.
1. Disinfection of milk
In the process of production, the newly milked milk is generally put into the milk can for rapid cooling in order to inhibit the reproduction of microorganisms and prolong the antibacterial duration of milk. The cooled milk needs to be sent to the factory for processing in time. That is, after filtration, purification, cooling, homogenization, sterilization and packaging and other processes, it has become people’s daily drinking sterilized milk. Sterilization is an important process in the production of sterilized milk. Pasteurization is generally used (invented by German microbiologist Louis Pasteur in the 1850s, so it is named after it). This method is divided into two disinfection methods: low temperature and high temperature. The low temperature sterilization method is to put the milk into a special pasteurizer and heat the milk to 62 ℃ ~ 65 ℃ for 30 minutes, while the high temperature disinfection method is to heat the milk to 73.8 ℃ ~ 76.6 ℃ for a duration of 1 to 10 minutes, or 82.2 ℃ for no more than 5 minutes. Then quickly cooled to 10 ℃. The purpose of cooling is to prevent the reproduction of residual spores and to maintain the quality of milk. In addition, the use of local method can also achieve the purpose of disinfection. That is, after boiling with high heat, a cream film is quickly formed on the surface of the milk (subject to the milk does not overflow), as if a piece of cloth is covered on the waves. Calculated from the time of forming the lipid membrane, the effect of pasteurization can be achieved by cooking for another 15 minutes.
The temperature and time of milk disinfection must be strictly controlled. Otherwise, it will not only fail to achieve the purpose of disinfection, but also destroy the nutritional composition of milk. This is because: first, boiling at high temperature for a long time will change the protein in the milk from the sol state to the gel state, resulting in a large number of protein condensation and precipitation. Second, the calcium in fresh milk is electrostatically combined with casein to form casein calcium that can be digested and absorbed by the human body. Compared with sterilized milk, casein in milk boiled for a long time is reduced by about 20%. Calcium becomes calcium salts that are difficult to be digested and absorbed by the human body; third, long-term boiling will also decompose lactose with low nutritional value; fourth, it destroys a variety of vitamins, including vitamin A. Therefore, in principle, sterilized milk is drunk directly, and there is no need to boil it. If you need to heat up, just put the bagged cow in hot water of 50 ℃ to 60 ℃ for a while.
2. Preservation of sterilized milk
Pasteurized milk is not easy to keep at room temperature. Milk is most afraid of the sun. In the sun, milk containing vitamin A, carotene, vitamin B1, vitamin B12 will be destroyed, so it is best to avoid the light cold storage. According to the experiment, milk can be kept for 12 hours when cooled to 13 ℃, so put the sterilized milk in bags that are temporarily undrunk into the refrigerator freezer, but not in the freezer. Because once the milk is frozen and then heated, fat and protein will be separated, solidified and precipitated. At this time, the fat will float, the milk taste will change, and the nutritional value will also be reduced. If you buy self-employed milk, it is best to drink it at one time after boiling and disinfection, and it is not suitable to keep it. If you want to save, you can use a small container, sealed storage, but the time should not be too long.
Nowadays, both bagged and bottled milk sold in the market are disinfected and processed by dairy processing enterprises after purchasing fresh milk from dairy farms and cattle farmers. There are two methods for manufacturers to use sterilized milk, one is instantaneous heating at a high temperature of 135℃, and the other is
Pasteurization. In pasteurization, milk is treated for 30 minutes at 62-63 ℃ or heated to 72-73 ℃ for 20 seconds. If the packaging is well sealed, bottled milk can be stored at room temperature for several months to a year. The shelf life of bagged milk is 2-3 days in summer and 5-7 days in winter.
A senior engineer surnamed Zhang in a dairy factory said that according to the production process, liquid milk can be divided into three types: sterilized milk, yogurt and pasteurized milk. In terms of disinfection methods alone, there are two kinds of “pasteurized milk” and “ultra-high temperature sterilized milk”. In terms of packaging forms, Tetra Pak can be roughly divided into four types: plastic bags, Tetra Pak, cartons and plastic bottles, among which Tetra Pak bottles are divided into pillow (bagged) and brick (boxed), all of which are made by Swedish Tetra Pak Co., Ltd., which is composed of 5-7 layers of paper and aluminum foil. According to experts, the shelf life and drinking methods of milk have a lot to do with packaging, and different packaging and disinfection methods determine the shelf life of milk.
Pasteurized (bag / roof) pasteurized milk: also known as pasteurized milk. After sterilization at about 80 °C for a few seconds, it is “short-acting milk”, which needs to be preserved at low temperature and the shelf life is generally 1-7 days. When the storage temperature exceeds 4 °C, the bacteria in the milk can still reproduce, so it can not be preserved for a long time at room temperature. Pasteurized milk includes full-fat and partially defatted products, which are suitable for families with fast disinfection and high purchase frequency.
Bagged milk is cheap, so it can be delivered to thousands of families and become the breakfast food for many families. The appearance of fresh milk in the shape of a house is packed with paper materials that are protected from light and in line with the concept of environmental protection, and the international “cold chain control method” is adopted. that is, the whole process from fresh milk extrusion to production, storage, transportation and sale is carried out at low temperature, and the shelf life can be up to 7 days. One of its characteristics is “fresh”: from milk extrusion to product filling is completed within 8 hours; second, the production technology is advanced, scientific, the nutrients are well preserved, and the nutritional indexes are higher than those of ordinary bagged milk. The house-shaped milk with rich flavor and mellow taste is the fine product of fresh milk, and its price begins to approach ordinary people after a great adjustment. However, because it is still at a disadvantage in price, house-shaped milk can not replace cheap bag pasteurized milk for a long time.
Ultra-high temperature (pillow bag / brick box) sterilized milk: also called high temperature milk. By using the instantaneous ultra-high temperature sterilization method, the sterilization, box forming and packaging of the packaged materials are completed at one time, that is, the process from packaging forming to product filling is carried out in the sealed aseptic area. Tetra Pak fresh-keeping cartons with 5-7 layers of protective film can protect vitamins in milk from sunlight. Tetra Pak packaged ultra-high temperature instant sterilized fresh milk is “long-acting milk” with a long storage life, which can enable consumers to reduce the frequency of purchase. The product itself does not need to be refrigerated, and the shelf life at room temperature is generally 8 months, but the premise is that once the package is opened, it should be refrigerated and finished within 3-4 days as far as possible. Tetra Pillow packaging is economical and more suitable for carrying out.

How to distinguish the quality of the packing machine?
The quality of the packing machine depends on the following points:
First, whether it is a professional manufacturer, there are only a few domestic packing machines that do well, such as Shanghai Yuzhuang.
Second, whether there is a sound quality control process
Third, whether there is a perfect after-sales service system
The most important thing is to consult a professional manufacturer.
