The melting temperature is between 160 to 170 °C. Polypropylene with higher melt flow rate (MFR; how easily the molten raw material will flow during processing).
•PP is commonly oriented (polypropylene film is extruded and stretched in both the machine direction and across machine direction it is called Biaxially Oriented Polypropylene, BOPP) to improve optical, mechanical, and barrier properties.
•BOPP is widely used as a packaging material for packaging products such as snack foods, fresh produce and confectionery.
