3, BOPP status and development trend of raw materials
3.1BOPP status of raw materials
Currently on the market are mainly three types of BOPP special resin, the first category is suitable for medium and low speed BOPP production line of polypropylene extrusion; second is suitable for high speed extrusion production line of polypropylene; third category is suitable for tall degree of smoke polypropylene film. The production of BOPP film in China at this stage mostly covered 65% of the market, which is more than consumption.
Market research results from the current view, almost all of the continuous internal polypropylene plant development and production of BOPP films in special material. Larger amount of main grade: Yangzi Petrochemical F1002B (where B is open agent added), Shanghai Petrochemical F280S and F280SO, Zhenhai Refining & Chemicals F280Z, Maoming Petrochemical F280M, Changling refinery in T38F, Guangzhou Petrochemicals F400-H CNOOCs HP425J, and Jinan Sinopec Jiujiang Petrochemical, Jingmen refining, petrochemical Wu, Daqing Petrochemical, Lanzhou Petrochemical T36F so.
In recent years, Chinas Sinopec in the theory of high-performance polymer materials to achieve a breakthrough, made the melt tension of stability theory. Under the guidance of the theory, from the polymer molecular structure design and control of manpower, enhancing the overall quality of Chinas petrochemical BOPP material as a basis for the development of the F280S, F280SO, F280M, F280Z and other high-speed stability can pull film Also distinctive BOPP resin. Meanwhile, Sinopec subsidiary production of T36F, EPT56F, F400H and other brands of performance has also been enhanced.
3.2 The application processing requirements for raw materials trend
China BOPP film industry has more than 20% average annual growth rate, and rapid growth to the BOPP manufacturers of raw materials put forward higher requirements. At present, the film production plant by gradually increasing film width and the deposition speed reduce costs and improve the competitiveness of enterprises, BOPP film width of 4 meters from the earlier period and gradually increased to 6 meters, 8 meters to 10 meters, film speed of more than 100 meters from the initial / min up to 450 m / min or more, increasing the thickness of thin films.
Electric film, cigarette film production of high quality although the deposition speed for no more, but the physical properties of the material also made a special standard.
With BOPP technology, high-speed, high-speed film pulling more and more common, on the product transparency, stiffness, and crystal points, thickness uniformity, etc. have become increasingly demanding, ultra-thin film, crystal film, non-gel composite film and other kinds of new products emerging. BOPP industry and technology development, supply of raw materials continue to make higher demands.
For such applications market demand, Chinas Sinopec in theory under the guidance of the results, organized a series of special resin BOPP R & D, currently has a rating for different production line codes. For example, the development of F2805 and F280SO products, having high tensile membrane stability, and good optical performance characteristics of products; F280Z with high tensile membrane stability, less soluble material, stiffness and optical properties of the optimal characteristics of an integrated, There used to precipitate a small surface, very little precipitation sticky roll edge; F280M with high tensile membrane stability, stiffness index products, many advantages, there are user-friendly products thinning. F280M precipitates rarely conducive to further development in the field of application of metalized film.
