Plexar PX3990: A new high-performance LLDPE tie-layer

May 07, 2025

LyondellBasell (LYB), a global leader in the chemical industry, is excited to announce the addition of a new high-performance LLDPE tie-layer to the Plexar portfolio, Plexar PX3990, that excels in film orientation applications. This innovative tie-layer represents an additional high-performance solution in the LYB comprehensive tie-layer product line.

Plexar PX3990 exhibits outstanding processability and adhesion after machine direction orientation (MDO) and further promotes the sustainability of MDO film by allowing downgauging compared to non-orientated films. While excelling in shrink film, Plexar PX3990 can also be a viable solution for many demanding applications in the oxygen barrier co-extrusion film market.

Plexar PX3990 exemplifies the leadership of LYB in the tie-layer market by creating a product with improved performance to provide solutions to meet customers’ needs," said Natalie Nichols, senior director of specialties and performance products at LYB.              

Developed in cooperation with MSI Technology, Plexar PX3990 has the support of leading experts in co-extrusion who have a deep understanding of the applications and markets. Utilizing our shared resources and experience, LYB and MSI Technology are able to meet the ever-changing demands and opportunities of the co-extrusion markets.

This product is currently available globally in a variety of packaging types. To learn more about this new high-performance product, please reach out to MSI Technology via their contact information below.
