HMW

High Molecular Weight (HMW)

High Molecular Weight (HMW) High-Density Polyethylene (HDPE) resins with very low melt indices (MI2 ranging from 0.03 to 0.1 dg/min) and very broad, multi-modal molecular weight distributions provide high melt strength and excellent impact properties.

These characteristics along with high tensile strength make HMW HDPE the resin of choice when producing very thin films for carrying heavy loads, which is required by retail carryout bags and institutional can liners for example.

HMW HDPE resins are typically processed by high stalk blown film extrusion.
