PROCESSING CONDITIONS

Borstar®FB2230 can be processed in most types of blown film equipment such as LDPE, LLDPE or HDPE

extruders. The balance of draw down properties and bubble stability is superior to conventional LLDPE and

LDPE. Thickness of 10 to >2000

m can be processed with good bubble stability. The product is well suited for

co-extrusion.

Recommended extrusion temperature is 190 - 210°C. A die gap of 1.0 - 1.8 mm will give the best balance

between extruder pressure and physical properties in the film. Wider die gap gives higher machine direction

orientation.

Borstar®FB2230 provides excellent mechanical properties balance by optimizing film processing parameters like

Blow up ratio (BUR) and Frost Line Height (FLH). Higher impact strength can be achieved by raising the FLH.

High BUR (>2) also results in improved mechanical properties.
