SLL118 is a Linear Low Density Polyethylene, copolymer of butene-1. This product is specifically designed for blown film extrusion in blends with other polyethylenes. The resulting films exhibit excellent processing performance, balanced optical and mechanical properties, and superior sealability. SLL118 boasts a very low gel amount and includes oxidant additives. Notably, this grade contains a minimum biobased carbon content of 87%, as determined according to ASTM D6866.
