ExxonMobil®LLDPE

LL 1002 series (Linear Low Density Polyethylene for blown and cast film applications)

Key Features

Recommended blown film extrusion conditions

LL 1002 series are LLDPE grades, offering high gloss and excellent draw down in both blown and cast film applications.

They may also be used as a blend partnerwith LDPE resins to improve film properties and processability.

Several additive packages are availableaccording to the required surface properties.

They are typically used in stretch film,produce bags, refuse bags and cast filmapplications.s

Blown film :
Melt temperature : 180 - 220 °C
High blow-up ratio

Cast film :
Melt temperature : 250 - 290 °C
For extrusion of 100 % LLDPE or LL-rich blends on unmodified LDPE equipment or through narrow die gaps (<1.2 mm), it is advisable to add PPA masterbatch to prevent melt fracture.
