branched low density polyethylene; (2) 25-55 weight percent of
inorganic filler; and (3) 0.5 to 5 parts by weight of liquid
ethylene α-olefin oligomer per 100 parts by weight of the
composition. Exemplary claim 1 is reproduced below.
A porous film molded from a composition comprising 25
to 55% by weight of polyolefinic resin and 75 to 45% by
weight of inorganic filler, in which the polyolefinic resin
comprises 98 to 70% by weight of linear low density
polyethylene and 2 to 30% by weight of branched low density
polyethylene, and wherein the composition further comprises
0.5 to 5 parts by weight of liquid ethylene-a-olefin
oligomer based on 100 parts by weight of the composition,
the porous film having a moisture permeability from 1500 to
4000 g/m__24hr. and a uniformness of thickness of 0.15 or
less.
