A NEW HIGH-PERFORMANCE LLDPE FOR BLOWN FILM APPLICATIONS

摘要

Conventional Ziegler-Natta catalyzed LLDPEs combine good mechanical properties with moderate processability. Efforts to enhance LLDPE properties further, through metallocene catalysts for example, generally result in a processability penalty. The present work describes a new development in LLDPE technology which produces resins with significant improvement in mechanical properties without sacrificing processability. Detailed blown film results show the performance improvement achieved by the new resins, compared to conventional LLDPEs, and the downgauging potential offered by the property improvement.
