PVC film under the market competition system

The fierce market competition has allowed the development of pvc film toward higher-end technology, and has also made pvc film widely used in all walks of life. Such as food, beverages, wires, cables, various building materials, and irregular packaging of valuables. Today we will explain its environmental protection and application safety issues.

　　Pvc transparent film has good transparency, good oil resistance, good barrier to water vapor and oxygen, and good corrosion resistance to acids, alkalis, salts and many other substances. Using food-grade polyvinyl chloride resin with low vinyl chloride monomer inventory and non-toxic additives, plastic packaging that meets national standards and can be directly contacted for packaging beverages, food and drugs can be prepared. However, once the vinyl chloride monomer content exceeds the standard or inappropriate additives are selected, it may cause safety problems in contact with food during the use of the PVC packaging film.

　　 On the other hand, we can see that the ecological environment will also have negative consequences due to its waste. Based on this, the environmental protection departments of many countries or regions in the world have issued relevant regulations to prohibit or restrict the large-scale use of PVC. Europe banned the use of PVC as food packaging materials in 1992, and Japan also banned the use of PVC packaging in 2000. According to the announcement of the Council of the World Packaging Organization, Japan, Singapore, South Korea and European countries have completely banned PVC as packaging materials; Taiwan, China has also issued the 'Waste Cleaning Law', expressly stipulating that PVC is banned as packaging materials from 2006.
