Recently, Tianjin Petrochemical Xiaowei successfully completed the industrial production of POF-specific resin, which broke the monopoly position of the product in foreign countries and laid the foundation for the Ministry to further seize the market.

The POF film is called the environment-friendly multi-layer co-extruded polyolefin heat shrinkable film. It uses linear low-density polyethylene as the middle layer and polypropylene as the inner and outer layers. After special processes, the inner, middle and outer layers are co-extruded. Made of heat shrinkable film. This product is widely used in the packaging field of special-shaped products such as beverages, convenience foods, daily chemical products, audio-visual products, books and periodicals, medicines, and electronic components due to its good transparency. It is widely used in the world and has been widely used in the world. Environmentally-friendly heat-shrinkable packaging materials approved by European and American markets.
After in-depth market research, technology developers found that the market capacity of POF membranes is relatively large, approximately 17-18 million tons/year. Among them, linear low-density polyethylene is used as an intermediate layer, and the dosage is about 12-13 million tons, and it is growing at a rate of 20%-30% per year. Due to technical limitations, the raw materials of the high-carbon linear low-density polyethylene resin as the middle layer of the product are all dependent on imports. After the developers mastered this situation, they immediately proceeded with an in-depth analysis of the molecular structure and boldly proposed that domestic hexene-1 monomers be used instead of octene-1 to produce high-carbon LLDPE resins. After the selection of molecular design, catalyst system and additive system, and through the adjustment and optimization of the polymerization process, the research team successfully developed the environment-friendly polyolefin heat shrinkable film DFDA-6010, and achieved industrial continuous production. The trial data tested by downstream users showed that the product was stable in film processing, with high adhesion to the outer layer, no bubbling, and all performances were at the import level, which could completely replace the imported film.
The successful R&D of DFDA-6010 is the first time in China to use POF resin produced by domestic hexene-1 monomer in the state of vapor phase condensation, which breaks the monopoly position of the product abroad and has significant social benefits. At the same time, the successful replacement of octene-1 with high-performance hexene-1 has opened up new ideas for the development of new products in the olefins sector.
