VERY LOW DENSITY POLYETHYLENE PRODUCED WITH SINGLE SITE CATALYST

摘要

Provided herein are VLDPE polymer compositions suitable for use in the manufacture of flexible films or sheets. In one embodiment, the copolymer comprises a polyethylene VLDPE resin with Mz/Mw of greater than 2, CDBI50 of greater than 55 and a single melting peak in DSC measurement. The polymer compositions disclosed herein may be suitable for use in the manufacture of films with improved balance of film toughness, processability and sealability in monolayer and multi-layer film structures.
