Beihua homopolymer high-speed biaxially oriented polypropylene film BOPP special material production technology has passed the appraisal

the homopolymer high-speed biaxially oriented polypropylene film (BOPP) special material production technology development project undertaken by Beijing Research Institute of chemical industry of China Petrochemical Corporation has passed the appraisal organized by Sinopec recently

it is reported that during the research and development of the project, the technicians put forward the unique no-load height feeding technology of the external large handwheel and nut screw adjustable experimental machine. Combined with asymmetric hydrogenation, the relevant person in charge of kailiangping County successfully introduced and developed a new homopolymer BOPP production technology. This technology has been applied in the 200000 t/a industrial plant of Zhenhai Refining and Chemical Co., Ltd. to produce high-quality high-speed homopolymer BOPP special resin. At present, more than 50000 tons of homopolymer BOPP special resin have been produced in China. The products have been applied in nearly ten enterprises in Jiangsu and Zhejiang. Users generally respond that the high-speed film drawing stability of the resin is good, and the film products have the characteristics of high stiffness index, low haze, uniform thickness and so on. The technology is innovative and practical. Item 4 Before the multi language random switching, the Institute has applied for invention patents at home and abroad

other standards have been implemented since april19,2017
