Borstar®, a state-of-the-art bi-modal proprietary technology owned by Borealis, supports the production of a wide range of enhanced PE and PP products for the most demanding applications by enabling molecular design. The Borstar® process offers simultaneous improvements in conversion economics as well as key environmental aspects such as energy efficiency and raw material recycling.

The Borstar® technology is based on a dual reactor process for bimodal production that yields broad molecular weight distribution while also providing a balance of processability and mechanical strength.
Borstar® MDPE resins are used in applications such as stand-up pouches (SUP) and heavy duty shipping sacks (HDSS). They are ideal grades for machine directed orientation (MDO) PE substrate films for PE and PE-fully recyclable laminates.

Key Attributes:
  • Unique matt surface
  • Excellent stiffness impact/stiffness balance
  • Outstanding bubble stability and melt strength
