BORSTAR® NEXTENSION TECHNOLOGY
Breakthrough technology delivering customized, circular solutions with outstanding performance
With the development and launch of the Borstar® Nextension technology, Borealis solidifies its position as an industry leader in innovation and technology. Thanks to proven Borstar® performance and unique single-site Borstar Nextension catalysts, Borstar Nextension Technology enhances the range of polypropylene (PP) and polyethylene (PE) properties and drives plastics circularity.
Borstar® Nextension PP – key benefits:
-
Broadens the range of PP properties thanks to its ability to tailor polymers for unrivalled higher purity, excellent transparency and optics after sterilization, as well as superior sealing and bonding at lower temperatures.
-
Drives plastics sustainability by supporting Design for Recycling and downgauging. This universal solution sets new standards by enabling material substitution in multilayer, multimaterial-based applications with mono-material solutions for flexible packaging
-
For customers in Flexible and Rigid Packaging, Non Wovens, Healthcare, and Mobility, Borstar Nextension Technology opens exciting new horizons for PP by uniting outstanding performance characteristics with enhanced circularity.

Borstar® Nextension PE – key benefits:
-
This breakthrough technology marks a new era in advanced polyethylene solutions, delivering superior toughness, sealing performance, and enhanced processability for packaging solutions that enable downgauging, improve cost efficiency, and support design for recycling—addressing the critical needs of today’s packaging industry.
-
Borstar Nextension PE technology sets new standards by enabling mono-material solutions that can replace existing multimaterial products, thus making it easier to sort and recycle at the end of life.
Introducing next-generation development materials at K
Borealis introduces Borstar Nextension PE technology at K2025 with two high-performance development materials, tailored to meet evolving market needs:
-
A cutting-edge solution that delivers double the toughness of first-generation metallocene PE materials, while maintaining stiffness and excellent processability, including superior bubble stability and throughput. With its unique mechanical performance and strong downgauging potential, this new material enables more sustainable, fully recyclable packaging with excellent performance characteristics. Designed for industrial and food packaging applications, it is ideally suited for Form, Fill & Seal (FFS) and frozen food packaging.
-
An advanced solution featuring a breakthrough sealing profile that reduces sealing initiation temperature by over 15% compared to first generation metallocene PE. This, in combination with the material’s outstanding mechanical properties, enables faster packaging speeds, best-in-class hot tack performance – making it perfectly suited for lamination, FFS, and food packaging.
