Patent ID: 8314187

Claim:
A multimodal medium density polyethylene polymer obtained using single site catalysis, comprising at least: (A) a lower molecular weight (LMW) polyethylene homopolymer component; and (B) a higher molecular weight (HMW) polyethylene copolymer component which is a copolymer of ethylene and one C3-12-alphaolefin; wherein the multimodal medium density polyethylene polymer has a density of 925 to less than 940 kg/m 3 and a comonomer content of 0.5 mol % to less than 2.5 mol %, and having an M w /M n of 3 to 8, and wherein the multimodal medium density polyethylene polymer is formed into a film having a Dart Drop (F50 ISO7765/1 method A) of more than 800 g and haze to thickness ratio of less than 1.5%/μm.
