Packaging industry in developed countries
experts predict that the aseptic filling and packaging technology for plastic bottles of low acidity and high acidity products will be further recognized and applied in the United States
what new developments will plastic bottle aseptic packaging achieve in the next few years? This largely depends on the level of economic development. Industry experts believe that gradually giving up the heavier hot filled plastic bottles and switching to the sterile filled plastic bottles with lighter weight and lower cost can be implemented on a large scale only when the economic development is relatively smooth
Dr. severgon paranianpan, director of technical reform business of Minute Maid branch in Houston, Coca Cola company, said: "in the long run, sterile filling has better economic benefits, but the high initial cost of investment is a great disadvantage. From the current economic situation, it is difficult to ask the company's management to invest 20million US dollars to buy a full set of sterile packaging production line."
Mr. rob Hoskins of Krones company (manufacturer of aseptic filling and packaging equipment) in Franklin, Wisconsin, USA, said: "front end investment is not the only obstacle. A considerable investment is needed in personnel training and production operation. Many beverage suppliers are waiting for others to bite this hard bone first, and then learn from them."
some manufacturers are waiting for the packers to adopt aseptic packaging technology. Frorito valtacio & Sons is a good example. The company's exquisite glass bottles and labels for its Arizona tea and fruit juice drinks have been widely praised. This summer, the company introduced several beverage products with heat filled polyethylene terephthalate packaging bottles. Mr. johnbalbany, general manager, said: "we also consider using sterile filling technology, but the packaging processing capacity of the packers is insufficient."
welch company - a packer headquartered in Concord, Massachusetts. Mr. ed Lena, the manager of the packaging R & D Department of the company, said: "due to the development of bottle making technology, 380 volt power supply, currently light-weight hot filled plastic packaging bottles can be used. Therefore, the cost difference between hot filled and cold filled plastic packaging bottles is not very large." According to Mr. Lena, Welch also considered using aseptic filling packaging technology when it recently launched a 10 Ounce special fruit juice beverage bottle. However, it turned out that the heat filled polypropylene multi-layer packaging bottle was attractive because it could be filled on Welch's 10 Ounce glass heat filled packaging line. This is in this case. It is difficult to sell the multi million dollar sterile packaging line to the company management
despite the above factors, sterile filled plastic bottles are still very attractive to many beverage companies. Although several of the beverages produced by Minute Maid are made from hot filled plastic bottles, But Parra can only reach a certain load every time he loads, Dr. niapan said: "We believe that hot filled plastic can not meet all the needs in the future. Compared with hot filled plastic bottles, sterile packaging allows users to have absolute freedom in packaging design, so there is no need to use vacuum packaging technology in packaging. In addition, it can effectively protect the taste and nutrition of beverages. Such comprehensive benefits must be paid attention to."
Dr. paraniapan believes that the trend of consumption development will also make beverage manufacturers gradually adopt sterile filled plastic bottle packaging. "Consumers don't just need simple drinks like fruit juice or milk. They also need to add some nutrients, vitamins and unique tastes. Sometimes they want to buy a drink made of milk and fruit juice," he said According to Dr. paraniapan, if the above-mentioned high-end drinks are packed by hot filling, it will have an adverse impact on the taste and some nutrients contained. He believes that to meet the new consumer demand, it is best to adopt the sterile filling high-temperature short-term treatment technology
low acidity beverage packaging is an attractive aspect in the field of aseptic packaging. Generally speaking, it is difficult for the packaging of low acidity products to keep the products on the shelf for a long time, because when the product processing or packaging operation fails to meet the aseptic disinfection standard, those deadly bacteria that cannot grow in high acidity products will grow and multiply in the non frozen low acidity environment. The U.S. Food and drug administration has approved square aseptic packaging for low acidity products. However, at present, the only sterile plastic packaging system for low acidity products approved by the U.S. Food and drug administration is produced by Bosch Company in bridgemen, Michigan, and has been used by Ross company for the packaging and production of Similac baby food and beverage since 1998
many insiders believe that the above situation will change soon. Mike Wallace, director of production and packaging business department of Ross food company in Ohio, thinks so. According to him, some dairy companies in the United States use plastic bottles to pack low acidity products and sell them in freezers, which has extended the effective consumption period of the products and achieved great success in business. These companies learn from their European counterparts and use the same equipment, processes and materials to extend the shelf life of their products. European companies do not have to worry that the US Food and Drug Administration will refuse to accept the quality of their products, so their packaging has a long shelf life. However, in the United States, if you want to use sterile filled plastic bottles to sell low acidity products at room temperature, you must apply to the U.S. Food and drug administration, which is both expensive and time-consuming
so far, rose is the only company that has not been rejected by the U.S. Food and drug administration. However, Mr. Wallace believes that the situation will change soon, and aseptic filling packaging technology will be widely used. At present, a large amount of funds are being injected. Sidel, Remi, shibuy and other companies are progressing smoothly in technological transformation. Sooner or later, they will be recognized by the U.S. Food and drug administration to prove that their plastic packaging bottles meet the commercial standards for disinfection and sterilization. If one company takes the lead, it will lead other companies. Mr. Wallace believes that nutritious beverages have special development prospects. He said: "distilled steel can packaging will definitely withdraw from the nutritional beverage packaging market. At present, it is no longer the preferred packaging method. The question is how much development work are nutritional beverage suppliers willing to do? How much capital are they going to invest?"
Jeff Keller of Tetra Pak company in Vernon Nills, Illinois, also believes that the sterile filled plastic bottle packaging of nutritional drinks has unlimited development prospects. He said: "although steel can packaging is a kind of high-end packaging, if a consumer is asked whether they prefer steel can packaging or resealable plastic bottle packaging, I think the answer is self-evident. It should not be forgotten that canned products should undergo a long period of high-temperature distillation and disinfection. The use of aseptic packaging technology can avoid the deterioration of products due to heat and maintain the original taste and nutritional value."
