 Enhanced performance for demanding pharmaceutical applications

LeneX™ UltraGuard® technology supports up to 40 % improved moisture barrier performance in HDPE packaging, enabling downgauging while maintaining the protection standards required for pharmaceutical use. LeneX™ UltraGuard® is engineered to improve polymer performance while maintaining processing efficiency, helping manufacturers balance protection, productivity, and quality at scale.

By enabling material reduction and simplified packaging designs, the collaboration also supports broader sustainability goals without compromising performance.
