How to achieve aseptic packaging of PVC shrink film

How does PVC shrink film achieve aseptic packaging? 'Aseptic' packaging is a method of sterilizing and packaging packaged drugs using instant ultra-high temperature sterilization technology in an 'aseptic' environment. Multiple composite materials are used for packaging through different forms of extrusion and compound molding. It has the advantages of better maintaining the medicines, extending the shelf life, saving energy, reducing packaging costs, and easy to achieve environmentally friendly packaging. The use of antibacterial polymer packaging materials for drug packaging can inhibit bacterial contamination, extend the shelf life of drugs, and ensure drug safety. Sterility will become the direction of flexible pharmaceutical packaging. Once the package contains bacteria, it will greatly shorten the shelf life of the drug, seriously affect the efficacy of the drug, and even cause drug safety accidents. Therefore, as the production standards of the pharmaceutical industry have been greatly improved, aseptic packaging has great potential in the field of pharmaceutical packaging. According to relevant statistics, from 2008 to 2012, the output of the global aseptic packaging market increased by 5%, with the fastest growth in South Asia and Southeast Asia, reaching 22% per year. It is estimated that by 2016, the capacity of the global aseptic packaging market will reach 153 billion liters, and the consumption of aseptic packaging will reach 333 billion. The new market demand mainly comes from South Asia/Southeast Asia and China, and their average annual growth rates will reach 11% and 3.5%, respectively. From a geographical point of view, the aseptic packaging market in Asia is growing rapidly, of which India and China are the two fastest growing countries in the world. Between 2010 and 2015, China alone will account for 28% of the added value of the global aseptic packaging market. The growth rate of Central America and South America will also exceed the world average, but the original foundation of these regions is relatively weak. With the increase in the application of aseptic packaging in the beverage, food and pharmaceutical fields, Brazil will maintain a double-digit annual growth rate in the next few years. There are about 400 imported gravure flexible packaging production lines in mainland China, and nearly 1,000 domestic wide-format high-speed gravure flexible packaging production lines. The manufacturing level of these production lines has approached or reached the level of developed countries; there are countless low-end narrow gravure flexible packaging production lines . In addition, in recent years, through the continuous efforts of Chinese flexo printing workers, coupled with the use of the world’s most advanced laser direct plate-making technology and high-quality inks, flexo plates and other consumables, the quality of flexo printing flexible packaging products has been increasing day by day, and more applications wide. With the continuous improvement of the level of equipment and raw and auxiliary materials and the increasing experience in production, operation and management, the technical level of China's flexible packaging industry has advanced by leaps and bounds, and the product quality has been greatly improved. In terms of printing quality alone, the printing level of China's flexible packaging industry can be said to have reached a very high level, and the printing quality is much higher than similar products in developed countries and regions in Europe and America.
