the pursuit of increasingly perfect preservation function has become the first goal of food packaging

at present, aseptic preservation packaging is very popular in the food manufacturing industry in all countries in the world, especially in developed countries. There are 1 in Britain, Germany, France and other countries, otherwise there may be a large number of waste products with out of size./3 drinks use aseptic packaging, and its application is not limited to fruit juice and fruit juice drinks, It is also used to pack milk, mineral water and wine. A mineral concentrate with calcium phosphate as raw material recently developed in Japan seeps into a water absorbing paper bag, and vegetables, fruits and other foods are transported in this paper packaging material. Fruits and vegetables can get nutritional supply from the mineral concentrate. Calcium phosphate can also absorb ethylene gas and carbon dioxide released by vegetables and fruits, inhibit the decomposition of chlorophyll and maintain freshness. At present, this technology has been popularized and applied in Japan. The United States has also launched a new fruit fresh-keeping bag made of natural activated clay and polyethylene plastic. This new fresh-keeping bag is like a very fine screen, and gas and water vapor can flow through the bag. The experiment shows that the fresh-keeping period of fruits and vegetables packed in new packaging bags can be more than doubled, and the packaging bags can be reused and easy to recycle. The latest fresh-keeping technology is developed by Britain and Germany. Deoxidizing materials are used on the inner walls of containers and lids to "eat" the excess oxygen in the container through these deoxidizing materials, so as to keep fresh and prolong the shelf life of products

green packaging has become a very important marketing tool and means

the food packaging industry has taken measures to promote the ecological and environmental protection of food packaging. Developed countries do not hesitate to use high and new technologies to create a Xintiandi for the green packaging of their own food industry. At the same time, countries all over the world take reduction, reuse, recycling and degradability as the goals and means of ecological and environmental protection packaging. In Japan, with the exception of tomatoes, strawberries, peaches and other melons and fruits, the vast majority of vegetables and fruits are not sold and packaged, and only fresh-keeping paper with special functions is used to prevent moisture penetration. On the one hand, it is not conducive to the development and reuse of new packaging materials according to the requirements of consumers. On the other hand, it is not conducive to the development and reuse of new packaging materials. On the other hand, it is not conducive to the separation of new packaging materials according to the requirements of consumers. On the other hand, it is not conducive to the development and reuse of new packaging materials. On the other hand, it is not conducive to the recycling of new packaging materials according to the requirements of consumers. In order to make it easier for consumers to identify the nature of plastic packaging materials and make waste recycling more simple and rapid, the United States stipulates that disposable plastic packaging materials should be marked with material name and classification code. At present, many developed countries have realized the modernization of packaging paper mold industry and the general promotion of paper packaging materials. For example, in Japan, even edible oil is mostly sold in paper packaging; The United States uses soybean protein to be processed by adding enzymes and other materials to make soybean protein packaging film. It can also be cooked and eaten together with food to avoid secondary pollution of food. In view of the unparalleled position and advantages of plastic materials in food packaging, developed countries are vigorously developing degradable plastic packaging materials to replace traditional plastic products, and many products have been successfully put into use, realizing the breakthrough of packaging materials and bringing infinite hope to solve the "white pollution"

the convenience of opening food packaging will be more important

the improvement work in this regard in many European and American countries mainly focuses on plastic packaging. One of the important trends is that when "see you every day" is a way for Xiao Deng to communicate with his partners, he no longer uses glass bottles, but uses packaging cans made of PET materials, These cans are safe to use and will not break, with molded handles on the sides. Britain and the United States and other countries have made creative improvements in packaging and launched a series of designs that are beneficial to users, such as imitating the cover of baby milk bottle on the bottle of beverage and mineral water, designing and using less than 300 hour switch type pouring device made of plastic on the milk box, and installing a large opening switch cover on the upper end of beer and beverage cans, so that users can drink as much as possible

China is a large country in food production and export, but the packaging technology and process of China's food industry have lagged behind for a long time. With China's entry into WTO, China's beverage packaging machinery and equipment manufacturing industry is facing severe challenges. At present, there are mainly five types of filling and production equipment for beverage packaging in the world, including glass bottles, easy to pull aluminum cans, composite packaging (Tetra Pak), PET bottles and pet cans (invented by plastona Co., Ltd. in 1985 and flowing into China in 1987), PVC bottles and so on. There is no pet can filling production line in China, and the other four have been introduced or manufactured. The proportion of the above packaging equipment is different in different countries: in Japan, PET bottles account for 11.9%, aluminum cans account for 13%; In the United States, glass bottles account for 42.7% and aluminum cans account for 35.9%

the technical level of foreign beverage processing machinery and equipment is generally high: (1) large production scale, fast speed and high efficiency. The 10 beverage companies with a high degree of mechanization in the United States account for more than 70% of the total output in the United States, while the output of Coca Cola and Pepsi accounted for half of the total market. The filling speed has developed from 150 bottles/min in the 1950s to 1000-1200 bottles/min now, up to 2000 bottles/min. (2) Microcomputer is widely used in automatic control of production process. Foreign packaging machinery adopts computer-controlled process and processing degree, and is equipped with various parameter measurement devices to complete packaging, measurement and testing. For example, in order to control the accuracy of ingredients, continuous measuring devices such as flow machine and speedometer connected with microcomputer are generally installed in the production system, and the computer controls the beginning and end of each process to control the concentration and flow of various ingredients. The error accuracy can be controlled within one thousandth. Generally, beverage production equipment is equipped with CTP system to control the cleaning process with microcomputer. (3) The material of the equipment is good, and the hygiene and quality are guaranteed in production. The equipment is generally made of stainless steel, and attaches great importance to the in-situ high-speed and efficient cleaning of empty bottles, solid bottles and automatic inspection equipment, so as to ensure the high hygiene of product quality

China's beverage machinery and equipment has developed from relying on foreign imports in the early 1980s to today, which can fully meet the needs of domestic beverage manufacturers. It follows the road of "introducing technology, digestion and absorption, independent innovation and gradual localization". Compared with foreign advanced technology, China's beverage processing still has some shortcomings and weaknesses, such as incomplete product specifications, poor complete sets, low automation level and control level, unstable single machine performance and less application of advanced technology. At present, there is still a certain distance between China and foreign major filling equipment manufacturers in terms of production and manufacturing equipment, processing means and design level. These are the areas where China's beverage machinery industry needs continuous efforts and improvement

in the 21st century, the development direction of China's beverage machinery and equipment manufacturing industry is: large-scale, high-speed and improving stability are the main objectives of development, and aseptic technology is the first choice for tackling key problems and developing technical equipment in beverage machinery manufacturing industry
