Material Notes:
LF118 is a linear low-density polyethylene, copolymer of butene-1, produced by the gas phase process. It is developed for blown film extrusion in blends with polyethylene. Films obtained with this product show a good processing performance balanced with good mechanical properties as well as sealability. It contains antioxidant additives. Its applications include: stretch films, liners, and LDPE and HDPE blends and packages for general use. Recommended processing conditions for film extrusion are about 170 - 210 ºC.
