Development prospect of PVDC

PVDC was researched during the World War II to avoid the metamorphism of drug and ammunition. It is featured with high-efficient oxygen resistance and wet resistance performance, which can effectively prevent the product from metamorphism, therefore, the industrialized production was started during the World War II for the military packaging. 

After the World War II, the application of PVDC was not only limited to the military packaging along with the technological progress and the rapid development of world’s drugs and food, it was still widely used in the food preservation, for it can effectively extend the life of food preservation and prevent the food metamorphism. For it is featured with the non-toxic, safe and reliable and other advantages, it has been widely used in the western developed countries as early as 1950s, and it was known as “green” packaging material by the western developed countries. However, the development of PVDC had been in trouble due to the emergence of EVOH and the development of two-way stretching nylon membrane. However, the rapid development appears along with the constant exploration of application due to its irreplaceable special performance, the development of modern packaging technology and the high requirement of military packaging. 

PVDC was started late in China, the domestic enterprise’s packaging concept is weak, so the material is not that widely used as in European and American region. Although our population is larger than that in the European and American developed countries, the total demand on the product in China is far lower than that in the developed countries seen from the total demand in the current market. PVDC products are used for 80% of drug blister package in Germany, and it is used for the vast majority of blister package in Japan. Current, the ratio is less than 5% in China. 

     PVDC product can improve the packaging level of drug and food and enhance the market competitiveness when prevent the product metamorphism. Although the packaging industry of food and drug in China is still in a comparatively-lower competition to certain degree, many production enterprises and packaging enterprises are only paying attention to the survival problem, the lack of the knowledge and information on the product in many regions hinders the development of the product, PVDC product has been widely concerned by the packaging industry along with the economic development, increasingly improving people’s living standard, constant enriching of knowledge and information, and increasing requirement on the product quality in China. In the future, the product will be the mainstream of food and drug packaging industry along with the constant enhanced healthy consciousness, further improved requirement on the food and drug quality. The widely usage of the product marks the progress of wet resistance, oxygen resistance and moisture resistance and other comprehensive properties in China, and the improvement of people’s living standard, it is believed that PVDC will have a great development potential in China in the future.
