The market demand for high barrier packaging materials in China is strong.
as a high barrier packaging material, PVDC composite film (including single film) has achieved long-term and sustainable development in western developed countries since the 1970s. It has taken the lead in packaging for more than 30 years instead of setting the number of days of production capacity. During this period, EVOH and only came out, but their functions were slightly inferior and could not be compared with them. So far, PVDC composite film, as a high barrier packaging, still ranks first. The global annual consumption of PVDC is about 120000 tons. In recent years, due to the rise of pharmaceutical packaging, BASF in Germany and Wuyu in Japan have expanded new plants. All this shows that PVDC, as a high barrier material, cannot be replaced by other materials at present
China has introduced PVDC packaging since the 1980s, and has its own PVDC manufacturing industry and corresponding processing industry since the 1990s. However, due to various reasons, such as the import of raw materials, film processing and even packaging technology and equipment, as well as China's economic foundation and corresponding living standards, the development of PVDC production and high barrier packaging in China is slow. According to the statistics of foreign countries in the early 1990s, the annual consumption of PVDC coated composite film in the world is about 110000 tons. Its main distribution: 50000 tons in the Americas, 30000 tons in the Pacific region and 30000 tons in Europe, while Africa is a blank. In the mid-1990s, according to the data released by Japan, the PVDC coated composite film has increased to 35700 tons, including 27000 tons of BOPP/PVDC composite film alone
at present, China consumes 15000 tons of PVDC resin and 1000 tons of latex (dry basis), almost all of which were imported in the past. In the past two years, the domestic supply of PVDC latex accounted for about 20% of the total. In terms of production capacity, DC composite films such as PV in China have a production capacity of 5500 tons/year, and the actual operating rate is about 40%. The annual output of PVDC coated composite film is about 2500 tons. If such output is calculated based on the average population, it is only 1% of Japan's average population, with an average of 0.002kg/person. The formaldehyde ≤ 10g/kg indicates the potential and hope of China's PVDC high barrier package market
in the 21st century, with the improvement of people's living standards, people began to pursue the quality of life, especially the color, aroma, taste and taste of food. This has led to fierce competition in the food market and a very gratifying new trend in high barrier packaging. PVDC coated composite film has undergone a qualitative change in the application direction. In the past, there were few repeat customers in food packaging, and began to use a large number of high barrier packaging materials小孩厌食不吃饭的原因
