Borealis is presenting the new Borstar Nextension polyethylene (PE) technology at K 2025 in Düsseldorf. According to the company, it is designed to provide packaging manufacturers with improved performance and greater recyclability.
The technology is based on specially developed single-site catalysts and extends the well-known Borstar platform. According to Borealis, it offers improved toughness, sealability and processability, allowing the production of thinner films with reduced material usage. It also enables monomaterial solutions that facilitate the replacement of multi-material packaging and thus support the recycling process. This is Borealis' response to the requirements of the EU Packaging and Packaging Waste Regulation (PPWR), which stipulates higher quotas for recycling and waste avoidance.
Development materials for flexible applications
With the launch, Borealis is bringing two new development materials onto the market. According to the company, one of them has twice the toughness of older metallocene PE materials, with the same stiffness and stable processing. It is particularly suitable for moulding, filling and sealing applications as well as for deep-freeze packaging. The second material is characterised by a lowered seal initiation profile, which, according to Borealis, increases processing speed and improves heat seal strength.
Supplement to polypropylene technology
The new platform complements the Borstar Nextension polypropylene technology that Borealis launched in 2022. The company also announced that it will develop further solutions for various industries in the future with a broad innovation pipeline.
