A new metallocene polyethylene (mPE) resin from ExxonMobil Chemical, Enable mPE 35-05, for tough, stiff, high clarity films, is said to provide significant downgauging opportunities while delivering outstanding processability across a wide range of applications and extrusion equipment.
Enable mPE 35-05 ‘displays robust and straightforward processing on both LLDPE and LDPE film line equipment, while exhibiting processing and shrink properties approaching LDPE, with the mechanical properties of higher alpha-olefin (HAO) resins of similar density’, according to ExxonMobil.
The improved processing is a result of its lower melt temperature, which promotes greater bubble stability with lower energy consumption than fractional melt index LLDPE. Long chain branching contributes to ‘excellent shear thinning characteristics that can deliver higher extrusion rates’.
The combination of good impact and tear resistance, with a low internal haze, is claimed to make the new resin ideal for tough, stiff, high clarity co-extruded films. Applications include shrink film, overwrap film, laminates and stand-up pouch, medium and heavy duty bags.
