The research and development of PET beer bottles attract attention, and complete biodegradation technology will become the focus

since the beginning of the 21st century, the overall level of China's packaging industry has shown great growth potential compared with some developed countries. With the rapid development of China's economy, China's packaging industry has also entered a healthy, stable and rapid growth stage. From 2006 to 2010, it will continue to maintain a high growth rate of 7%, and the total output value will reach 450 billion yuan. China's food, beverage, pharmaceutical, thermosetting molded sheet, tobacco, household chemicals, electronics and other industries continue to develop rapidly and healthily, which also provides a broad market for the packaging industry at home and abroad

according to statistics, from the current situation, the global demand for packaging machinery is expected to grow at an annual rate of 5.3%, reaching US $29billion by 2005. The fastest growth in packaging equipment production is in developing countries and regions; Developed countries will benefit from stimulating domestic demand, and look for local suitable manufacturers in developing countries, especially in food processing manufacturers to invest and provide packaging machinery and equipment

Pet beer bottles will become the focus of the whole industry

with the rapid development of China's beverage industry, beverage packaging has also become more colorful. From traditional glass bottles to the most popular pet beverage bottles, there are more and more varieties and more novel shapes. At present, the most popular pet beverage packaging was first introduced by PepsiCo in the 1970s. Its characteristics of low price, transparency, air tightness, good pressure resistance and easy modeling make it more and more widely used in beverage packaging. In the early 1990s, Japan introduced heat-resistant PET production equipment, so that PET bottles can be hot filled. At present, the proportion of PET materials used in the packaging of carbonated beverages, fruit juice and fruit juice beverages, tea beverages and bottled drinking water in the world's major beverage countries has exceeded 60%

when PET material is used in the beverage packaging industry, the air pressure quality required for bottle blowing process is gradually improved. In order to meet this large market, AF has developed a series of 40bar oil-free air compressors. At present, more than 1500 AF air compressors are widely used in more than 100 countries in the world

over the past four years, the sales of AF products in China have developed steadily. With the continuous improvement of domestic similar products, AF is also constantly improving itself, reducing costs on the basis of ensuring quality, and achieving double progress in service and sales, which is very important for the development of AF in China in the next few years

reviewing the development of the industry, the peak period of pet development in China's beverage industry was from 1998 to 2001, and this field has been in a stable period of development since 2002. For the future, we are optimistic about the PET beer bottle market, which has great development potential and can even exceed the existing market demand for fruit juice and drinking water. At present, many enterprises at home and abroad have developed PET beer bottles, and the development of PET beer bottles has become the focus of attention in the whole industry. PET beer bottle production lines have appeared in foreign markets. It is believed that there will be more significant breakthroughs in this field in the future Chinese market

there are rules to follow in the quality control of food packaging

at present, flexible packaging has become the mainstream of food packaging because of its unique advantages of light weight, beauty, excellent performance and low price. Its performance and quality are more related to the practical problems of keeping food fresh, preventing deterioration and facilitating transportation and storage in the process of storage, transportation, processing and sales. How to solve these problems effectively, economically and conveniently is very necessary to detect and control packaging materials, and has attracted the attention of more and more food manufacturers, packaging material suppliers and even consumers. At present, the inspection and control of food packaging is mainly reflected in the following two aspects

(I) barrier test

barrier usually refers to the barrier effect of packaging materials on the penetration of gases, liquids, etc. Because the barrier performance directly affects the quality and shelf life of food and other key issues, it is important to remove the connecting oil pipe between the host and the oil source control in many packaging test projects. Taking our common food packaging as an example, the oxygen permeability of dairy packaging is crucial to the shelf life of milk. A large number of test results show that for fresh milk packaging, if the oxygen permeability of the packaging is between 100-150, the shelf life of refrigeration is about 10 days, and the oxygen permeability is controlled below 5, then the shelf life can reach more than 1 month; For cooked meat products, we should not only pay attention to the oxygen permeability of the material to prevent the oxidation and deterioration of meat products, but also pay attention to the moisture resistance of the material to prevent the product from losing a large amount of water and making the color darker and darker; For fried foods such as instant noodles and puffed foods, the barrier performance of packaging materials can not be ignored. The packaging of such foods is mainly to prevent the oxidation and rancidity of products. Therefore, it is necessary to be closed, isolated from the air, protected from light and gas. The common packaging is vacuum aluminized film. Through testing, the oxygen permeability of such packaging materials should generally be below 3 and the moisture permeability below 2; There is also a common modified atmosphere packaging in the market, which not only controls the oxygen permeability of the material, but also has certain requirements for the permeability of carbon dioxide. In conclusion, it can be seen that the importance of packaging barrier testing in packaging quality control is becoming increasingly prominent, - and barrier testing is consistent with the current upsurge of the global flexible packaging industry to pursue high barrier products, "said Cao Jian, executive vice president of China Plastics Processing Industry Association, whose design also represents the cutting-edge technology of packaging testing. At present, the testing equipment used for barrier test mainly includes permeability tester, moisture permeability tester, oxygen permeability tester, gas permeability tester, container/film oxygen permeability tester, etc

(II) strength test

strength is a comprehensive index, which is the comprehensive embodiment of the tensile strength, breaking strength and deformation rate of packaging materials, the heat sealing strength of sealing, and the composite strength of film. The physical index specified in relevant standards is also the refinement index of strength requirements. Common instruments used in this aspect include thickness measuring instruments suitable for accurate thickness measurement of films, papers and other products, sealing testers for testing the sealing effect of the whole package, and electronic tensile testing machines for testing the tensile, peeling, tearing, heat sealing strength of films, composite films, rubber and other materials. Tear tester suitable for tear resistance test of film, paper and other products, heat sealing tester for measuring parameters such as material heat sealing temperature, heat sealing time and heat sealing pressure, friction tester for measuring sliding dynamic and static friction coefficient on the surface of film, sheet and other materials, torque tester for opening or tightening force test of rotating bottle cap, impact, viscosity, compression resistance and other test instruments

the endless emergence of new products and materials for flexible packaging, and the continuous innovation of packaging inspection and control technology and equipment have provided powerful help for quality control, guiding processing, and studying the properties and properties of materials; At the same time, the digitalization of packaging quality control makes the manufacturers of packaging materials have rules to follow, and the users of packaging materials have evidence to follow. Food packaging quality control is no longer an empty word

complete biodegradation is the future development trend of food packaging

to ensure food safety and quality, food packaging is one of the important components, and the selection of packaging materials that meet the requirements is more important. The state will implement a compulsory certification system for food packaging products, which means that enterprises producing plastic bags and disposable tableware must pass this certification, otherwise they can no longer produce

Qingdao kangwen has introduced the world's most advanced Biodegradation Technology from New Zealand. The biodegradable plastic raw materials, biodegradable plastic additives and food packaging products produced and sold have passed the inspection of the national environmental protection product quality supervision and inspection center, and this technology has also obtained the EU biodegradation technology certification, At the same time, it fully complies with the requirements of the EU directive "2002/72/EC: plastic materials and products in contact with food", and can be safely used in food packaging. This technology fills the technical gap in the same industry in China. The food packaging bag made of bioplastics additives is strengthened, so that the polymer has complete biodegradability. After being stored in the natural environment for 3 to 12 months, it can be completely biodegradable and converted into carbon dioxide and water, eradicate "white pollution", and realize green environmental protection in the true sense. More importantly, the tension, elasticity, toughness and transparency of this food packaging bag are still well maintained, and can be used as normal as ordinary food packaging bags. In addition, before the degradation of the product, it will not affect its recycling, and can realize circular economy. This technology was successfully developed in the UK in 2003. In the past two years, this technology has been vigorously promoted and used by many European and American countries, such as Britain, France, Italy, Germany and the United States, and has been recognized and appreciated by relevant environmental protection experts in the world. Since the establishment of the company in October 2005, most of its customers have come from export enterprises (exported to the European Union, the United States, Japan and other countries). Domestic food enterprises seldom use biodegradable plastics for food packaging

with the rapid development of social economy, people's awareness of environmental protection and the continuous improvement of production quality, using green packaging to extend the freshness and shelf life of food, there is a great friction between its upper and lower ends and the support of the experimental machine, reducing the impact of packaging on the environment, etc., which puts forward higher requirements for packaging materials, which is also the focus of the food packaging industry. In this regard, the United States and the European Union have high requirements for food packaging. First of all, real environmental protection products must be used for packaging. Secondly, the packaging does not cause secondary pollution to the environment. It is required not only to recycle and save resources, but also to be fully biodegradable. It is believed that this is also the future development trend of China's food packaging industry

enlightenment from the development of food packaging in the United States

a report by FPA in the United States shows that the packaging market in the United States has a very broad prospect. The food industry is the largest industry in the United States, and almost all models and models are used in the food industry. Among the U.S. food industry, vegetables and fruits account for the largest proportion of the annual demand for packaging machinery. From 1994 to 2005, the demand increased year by year, accounting for 18.4% in 1994 and 20.3% in 2005; The packaging machinery required for meat is the second; Dairy products ranked third; Bread ranks fourth; Grain and fruit ranked fifth. Except for meat products, the proportion of annual demand value of dairy products and grain and fruit packaging machinery in the total demand value of the food industry showed a downward trend. The average annual growth rate of the demand for packaging machinery in the food industry from 1994 to 2000 was 7%. The U.S. food industry introduces thousands of new products every year, which accelerates the upgrading of packaging machinery. Therefore, the innovation speed of packaging machinery used in the U.S. food industry has always been in the first place

at present, most new food packaging in the United States mainly uses petrochemical products as raw materials, and more and more people use plastic cans and bottles. Plastic products will gradually replace glass products. In some cases, they can also replace glass products, and even glass products. The reason is that they are light, which can reduce transportation costs. Traditional fiber packaging materials have a trend of being phased out. Polypropylene film is most likely to completely replace cellophane, while
