Patent ID: 7608327

Claim:
A film produced from a polyolefin blend that has a density from 0.935 to 0.955 g/cm 3 , said blend comprising: (a) greater than 50 wt. % of HDPE having a density greater than 0.955 g/cm 3 and an MI 2 less than 1.0 dg/min.; and (b) LLDPE having a density from 0.900 to 0.925 g/cm 3 and an MI 2 less than 5.0 dg/min.; wherein the film has a thickness from 50 to 200 microns, a modulus in the machine direction (mod MD ) from about 75,000 to about 130,000 psi, a tear strength in the transverse direction (TS TD ) greater than in the machine direction (TS MD ), and a TS MD expressed in grams and measured at a film thickness of 100 microns, defined by: TS MD >1544−(11.2)(mod MD /1000 psi).
