Abstract
Blends of very low density polyethylene produced using metallocene catalysts (mVLDPE) and high density polyethylene (HDPE) are disclosed. The polymer blends include a metallocene-catalyzed VLDPE polymer having a density of less than 0.916 g/cm3, the VLDPE polymer preferably being linear and without long chain branching, and a HDPE polymer having a density of greater than 0.940 g/cm3. The polymer blends are particularly suitable in blown and cast film applications.
