ExxonMobil®LLDPE

LL 1201 (Linear Low Density Polyethylene for blown film applications)

Key Features

 Recommended blown film extrusion conditions
LL 1201 series are LLDPE grades, offering excellent combination of stiffness and optical properties (when blended with 10 - 20 %LDPE)

It is typically used in bread bags, producebags, textile packaging and shoppers.

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

For extrusion of 100 % LLDPE or LL-rich on unmodified blends on unmodified LDPE equipment or through narrow die gaps (<1.2 mm),it is advisable to LL1201KG or to add PPA masterbatch to prevent melt fracture.
