Patent ID: 7659343

Claim:
A film layer made from a polymer composition, wherein the composition comprises (A) from 10 percent (by weight of the total composition) to 95 percent (by weight of the total composition) of at least one homogeneously branched ethylene/alpha-olefin interpolymer having: (i) a density from 0.86 grams/cubic centimeter (g/cm 3 ) to 0.92 g/cm 3 , (ii) a molecular weight distribution (Mw/Mn) from 1.8 to 2.8, (iii)a melt index (I 2 ) from 0.2 grams/10 minutes (g/10 min) to 200 g/10 mm, (iv) substantially no high density fraction; and (B) from 5 percent (by weight of the total composition) to 90 percent (by weight of the total composition) of at least one heterogeneously branched ethylene polymer having a density from 0.88 g/cm 3 to 0.945 g/cm 3 ; wherein the polymer composition has a melt index which is from 0.5 grams/10 minutes to 30 grams/10 minutes and which is lower than the melt index of component (A).
