POF heat shrinkable packaging film has a wide range of uses, a broad market, and has the advantages of environmental protection and non-toxicity. Therefore, it has been widely valued by developed countries in the world and has basically replaced PVC heat shrinkable packaging film as the mainstream product of heat shrinkable packaging materials. The production of this series of products in my country began in the mid-1990s. There are more than ten production lines in China, all of which are imported equipment, with a total production capacity of about 20,000 tons. Due to a certain gap between my country’s packaging technology and internationally developed countries, the application of three-layer co-extrusion series of heat-shrinkable packaging films in China is still in the preliminary stage, and the scope of application is still relatively narrow, limited to beverages, audio-visual products, convenience foods and a small amount of daily chemical products In a few areas, the annual demand is about 2 to 50,000 to 30,000 tons.

PVC heat shrinkable film also occupies a considerable heat shrinkable packaging market, with huge development potential. With my country’s accession to the WTO and the integration of the international market, the gradual increase in packaging requirements for a large number of export commodities, and the rapid development of domestic supermarkets, the application of three-layer co-extruded heat shrinkable packaging film will increase rapidly. It is foreseeable that the three-layer The market prospect of co-extrusion series heat shrinkable film is very broad.
