Beijing Chemical Industry Research Institute has successfully developed high-quality homopolymer BOPP

The Beijing Chemical Research Institute cooperated with Zhenhai Refining & Chemical Co., Ltd. and successfully developed homopolymeric biaxially oriented polypropylene (BOPP) under the designation F280Z. In this BOPP development process, Beijing Chemical Industry Research Institute adopted a self-developed electron donor control technology, researched and developed a unique homopolymerized BOPP production process, and tested on a 200,000 t/a PP unit of Zhenhai Refining & Chemical Company. Produce high-quality BOPP special materials, value-added products about 300 yuan / t, in July began mass production, monthly production of more than 5000 t, for refinery PP device to explore new products to explore a new path.

The trial-produced products were first tested in Zhejiang Huabin Packaging Materials Co., Ltd. Pulling the film at a speed of 420 m/min, tried 700 t no membrane breakage, and the product had a high degree of stiffness. The haze was only 0.5%; the ash content in the raw material was low, and the filter replacement cycle was extended to about 30 d; the core was also realized. The use of layers and surfaces makes the surface layer ideal. Subsequently, the application of nearly 10 companies such as Jiangsu Shuangliang Group Hengchuang Packaging Materials Co., Ltd. and Hangzhou Xiaoshan Huayi Plastics Co., Ltd. also showed that the product has the same advantages.
