Borealis’ new Borstar® Nextension polyethylene technology sets benchmark in performance and circularity

Introducing next-generation development materials

Borealis introduces Borstar Nextension PE technology 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.

“Borstar Nextension PE technology will expand our portfolio with highly efficient and recyclable solutions,” adds Craig Arnold, Executive Vice President Polyolefins, Circular Economy Solutions and Base Chemicals. “This is just the beginning of a robust innovation pipeline that will serve customer needs across multiple industries.”

Visitors to K 2025 will have the opportunity to learn about the new Borstar Nextension PE development materials at the Borealis and Borouge stand Hall 6, Stand A43, and discuss how these material grades can help them meet their sustainability and performance goals.

The new Borstar Nextension PE technology complements Borstar Nextension Polypropylene (PP) technology which was introduced in 2022.
