Borealis is uniquely positioned to meet the complex requirements of LIB pouch films
Borealis’ innovative three-layer cast polypropylene (cPP) concept for polymer–aluminum laminates used in lithium-ion battery (LIB) pouch cells—first introduced in September and showcased at K 2025 in October—continues to address the growing demand for high-performance, locally available materials in the rapidly evolving battery ecosystem.
With a longstanding heritage in the energy and mobility sectors and deep expertise in flexible packaging, Borealis is uniquely positioned to meet the complex requirements of LIB pouch films, ensuring safety, durability and processing efficiency. The new three-layer cPP laminate structure offers excellent deep-drawing behavior for efficient cell manufacturing, helps enable hermetic pouch seals with high seal strength to support battery safety, and provides durable laminate bonding and adhesion for long-term performance.
As global battery production expands, the ability to source key materials locally is becoming a critical strategic advantage. Portable energy storage plays a central role in decarbonization, supports strategic autonomy and enables applications well beyond electric vehicles. Borealis’ efforts align with European initiatives such as the EU Battery Booster package, as well as major public investments and regulatory frameworks—including Horizon Europe and the Innovation Fund—designed to accelerate battery manufacturing, secure critical raw materials and strengthen Europe’s industrial competitiveness and energy resilience.
This development also underscores the importance of collaboration. From the Borealis innovation lab to film producers, laminators, adhesive specialists, battery technology advisors and cell manufacturers, partners across the value chain bring essential expertise to advance the project. Following successful internal testing and strong early results from customer trials, the solution is now moving into the next phase of validation with an independent testing institute specializing in advanced battery technologies.
