1. A film having at least one layer comprising a homogeneous interpolymer of ethylene and at least one comonomer selected from the group consisting of C3-C20 α-olefins, dienes, and cycloalkenes, wherein the interpolymer is characterized as having:
a. a density of from 0.910 to 0.930 g/cm3,
b. a melt index (I2) of less than 2.5 g/10 minutes,
c. an I10/I2 of at least 10,
d. a molecular weight distribution Mw/Mn of from 2.1 to 5; and
the film having a haze of less than about 12% at a thickness of about 2.8 to 3.2 mils.
