Material Notes:

LF320 is a linear low-density polyethylene, copolymer of butene-1, produced by the gas phase process. It was developed for cast film extrusion. Films obtained with this product show a good processing performance balanced with good optical and mechanical properties as well as processability. It has a very low gel amount. It contains processing aid and antioxidant additives. Its applications include: stretch films, liners, LDPE and HDPE blends, and packages for general use. Recommended processing conditions for film extrusion are about 170 - 210 ºC.
