PE protective film is a protective film with special polyethylene (PE) plastic film as the base material, which protects the product from pollution, corrosion, scratches, etc. during production, transportation, storage and use, and makes the product surface Maintaining the original advantages such as smoothness and luster can improve the quality of the product and its competitiveness in the market. Due to its clear and glossy surface protection and low price, in the past 30 years, PE protective film has achieved unprecedented success in the packaging market. Not only has it successfully replaced cellophane, but it has also rapidly developed its own market, especially It is the composite film that replaces the paper. At present, the global annual consumption of protective film exceeds 3 million tons, and it is growing rapidly.

With the development of my country's PE protective film production technology, a large number of better PE protective film manufacturers have emerged, quickly transforming our country from a net importer of protective film to a net exporter, which has greatly contributed to my country's economic development. Contribution. The main production of optical protective film was initially concentrated in industrialized countries such as Japan, the United States and Europe. Because of the earlier industrialization in Europe and the United States, it entered the requirements for surface protection of products earlier than the Asian region to reduce the circulation from the factory to the market. In the link, the loss of the surface scratches encountered in the process of product transportation, handling, storage, and even display. European brands dominate the world in the protective film of rubber-based glue, and because of its characteristics, the protective film of rubber-based glue is still used in the post-processing industries such as stainless steel plate, aluminum plate, and even some plastic parts.

In terms of scientific and technological innovation, PE protective film has increased investment in research and development. At present, my country’s fastener industry is accelerating the pace of adjustment. The change in the direction of precision and speciality, from production-oriented to production-service-oriented, has clearly highlighted the concentration of the fastener industry. Three major fastener industry clusters in the Yangtze River Delta, the Pearl River Delta and the Bohai Bay Rim have been initially formed, and several fastener industry bases have been built in Jiaxing, Ningbo, Wenzhou, Dongguan, Hebei Xingtai, and Yongnian. In the 21st century, market competition has further intensified. In order to maintain the sustainable and stable development of the fastener industry, we have proposed a new idea of "adjusting in development and upgrading in adjustment", and adhere to the adjustment of market structure and product structure. To promote enterprise restructuring and industrial agglomeration, and promote the transformation of the entire industry’s economic growth mode.

The PE protective film is a low-density product, which is reflected in: the same weight, the length of the PE film is more than twice the length of the PVC film. At the same time, it is non-shifting, especially suitable for printed wires with low adhesion (such as rubber wires) and white wires. It is more effective to prevent wire printing from falling off and ensure that white wires do not turn yellow. At the same time, due to the high transparency of the product, it can be Packaging products are more beautiful. This product is widely used in wires, cables, hoses, steel pipes, various finishing rollers, mechanical equipment, hardware accessories, furniture, building decoration materials, and tourist sports shoes. The disadvantage of PVC winding film is that it is easy to break during transportation, has poor viscosity and is easy to loose, but the price is low.
