Ops heat shrinkable film is a kind of functional, environment-friendly heat shrinkable film, which can be heat shrinkable, with good body packaging effect, high transparency and good toughness. it is one of the most popular types of environment-friendly heat shrinkable packaging materials. From the development benefits of raw materials and molding technology, environmental protection and consumer demand, the market capacity of ops heat shrinkable film expanded rapidly. In the next three years, the global ops heat shrinkable film market will maintain an annual growth rate of 6.2%. The rapid growth of downstream demand market is the development opportunity of ops thermal shrinkage. Ops heat shrinkable packaging film is widely used, and the market is broad. With the advantages of environmental protection and treatment, it does not produce toxic odor, and conforms to the US USDA and FDA standards. This is a very popular shrink packaging material in recent years, and we often talk about it. Because of its good environmental protection performance, it has been widely used in various fields of production and processing, and is also an important way of daily commodity packaging. Therefore, PVC heat shrinkable packaging film, which is highly valued by developed countries in the world, has become the mainstream product of heat shrinkable packaging materials. China’s series of products began in the mid-1990s. Now there are more than ten production lines, all of which are imported, and the total production capacity is about 20000 tons. Because there is a certain gap between the packaging technology in China and that in developed countries, the application of three-layer co extrusion series heat shrinkable packaging film in China is still in the initial stage, and the application scope is relatively narrow, with only beverage, audio and video products, convenient food and a small amount of daily chemical products in some regions. The annual demand is about 2%? 5 tons 3000000 tons. PVC heat shrinkable film also occupies a large heat shrinkable packaging market, with huge development potential. With China’s accession to the WTO and international market standards, the requirements for packaging of a large number of export commodities are gradually increasing, and the rapid development of supermarkets in China, the application of three-layer co extruded heat shrinkable packaging films will grow rapidly. It can be predicted that the market prospect of three-layer co extruded series of heat shrinkable films is very broad.
