LLDPE made via Spherilene
LL-235F7 is a linear low-density polyethylene resin (LLDPE) obtained by gas phase technology process. This grade is suitable for the production of lamination, agricultural, shrink and general films. LL-235F7 combined good processability and melt strength with excellent mechanical properties, high sealability, good hot tack force and superior optical properties. This grade approved for food contact applications.
