â—†Development: Borealis Group â—†Features: The newly developed PP grade Borclear RB707CF breaks through the limitation that traditional extrusion blown film cannot use PP resin. According to reports, the new grade has excellent optical properties, good processability, and balanced rigidity and toughness. Its melt flow rate is 1.8g/1 Omin, and it can be directly connected to metallocene polyethylene and firmly bonded. Prior to this, most PP grades were not able to perform extrusion blown film processing due to poor processability and low toughness, especially poor optical performance. â—† Application: The application target of this new product is to make the sealing layer of a coextruded multilayer film for flexible packaging.
