Borstar FB4230 Borealis Polyethylene, Linear Low Density

Product Description

Borstar FB4230 is a linear low density polyethylene film grade combining good and flexible extrusion behaviour, excellent draw down and superior mechanical properties.

Blown film extrusion with Borstar LLDPE is comparable to LDPE, but with better flexibility in film thickness range and draw down.

Applications
Food Packaging, General Packaging, Pouches, Frozen Food Packaging

Borstar FB4230 contains antioxidant.
