Borstar bimodal HDPE for blow moulding enables converters to produce containers which are considerably lighter, but deliver better performance in terms of:

• Weight Reduction
  Bottle weight can be reduced by as much as 10 per cent, thus improving its stacking performance and reducing cost in transportation and storage.

• Better Environmental Stress Cracking Resistance (ESCR)
  The ESCR is three times higher than that of conventional products, thus providing excellent stiffness and strength.

• Superior Top Load Performance
  Bottle top load is directly related to stacking performance of filled bottles.  Bottles in a warehouse at the bottom of the stack carry a lot of weight, and are therefore more exposed to stress cracking, especially in Asia, where temperature is higher.
  
  
• Shorter Cycle Time
  Bimodal materials flow better in the extruders, and can be extruded at temperatures 30 to 40°C lower than unimodal products. This results in shorter cooling time and higher output. Lower pressure in the extruder, less back pressure and melt back flow contribute to a more stable production.

• Low Taste and Odour
  Low additive migration means no issues with milk and juices.
