At Borealis, we know that our customers need to balance a lot of requirements. Materials must run efficiently on high-speed lines, meet strict food-contact standards, deliver high performance and flawless shelf appeal, and support the transition to a circular economy.
Polypropylene grades based on Borstar Nextension Technology offer outstanding packaging efficiency and product safety

Borstar® Nextension Technology was created with these needs in mind. Built on our proven Borstar platform, it enables a step change in polypropylene (PP) performance— opening the door to versatile solutions with precisely tailored properties that are also easier to recycle.
Borstar Nextension Technology combines the proven Borstar process with a new generation of proprietary single-site catalysts. This combination allows far more precise control over how polymer chains are formed. In practical terms, it lets us design PP with exactly the balance of strength, clarity, and sealing performance that specific applications require.
This makes it possible to achieve:
Because we can build multiple specified properties into a single material, structures that once required several different layers can now be optimized. That simplifies recycling and helps brand owners move toward monomaterial packaging—an important step in meeting the EU Packaging and Packaging Waste Regulation (PPWR) target of 100 % recyclable packaging by 2030.A growing family of Borstar Nextension PP grades is already proving how these advantages translate into real-world benefits in packaging and nonwoven applications.
Designed for flexible food packaging, BorPure™ RE539MF is a next-generation random PP that combines very low overall migration—ensuring food safety—with exceptional optical purity for maximum shelf appeal. Its broad sealing window and low seal-initiation temperature give converters and packers greater flexibility and faster, more reliable sealing on high-speed lines.
BorPure™ RB787MF, another next-generation random PP, delivers outstanding purity and best-in-class organoleptics, making it ideal for use as a transparent, heat-resistant skin layer in blown films. Converters benefit from stable processing, excellent film clarity, and strong mechanical performance—qualities that support both thin-gauge flexible packaging and thick-walled thermoformed webs.
Borealis HG485FB is a spunbond PP grade developed for hygiene and technical nonwoven fabrics. Its broad processing window and excellent spinning performance enable the production of finer fibers and stronger webs at lower basis weights, reducing material use and associated CO₂ emissions without compromising softness, tensile strength, or coverage.
“With Borstar® Nextension Technology, we’re helping our customers stay ahead in the rapidly changing consumer products landscape. By combining superior performance with enhanced circularity, these new advanced grades make it easier to design efficient, recyclable solutions that also stand out on the shelf.”

The Nextension platform now extends beyond PP. We have introduced Borstar® Nextension Technology for polyethylene (PE), which brings the same ability to precisely tailor molecular design, achieve strong downgauging potential, and create fully recyclable monomaterial packaging to a new set of flexible packaging applications.
Borstar Nextension Technology is another example of how we’re making everyday life easier by creating high-performance materials that help our customers achieve efficiency, meet regulatory targets, and accelerate the shift to a circular economy.
