Application No. 08/466,171
polymer selected from at least one of the group consisting of ethylene-propylene-butene-1
terpolymer, ethylene-propylene random copolymer, ethylene-propylene block copolymer,
isotactic polypropylene, low density polyethylene (LDPE), very low density polyethylene
(VLDPE), linear low density polyethylene (LLDPE), medium density polyethylene (MDPE),
polyvinylidene chloride (PVDC), polyvinyl alcohol (PVOH) and acrylic, said polymer being
compounded with an effective amount of anti-blocking agent, but being substantially
devoid of silicone oil;
(2) providing a lower major surface of core layer (b) with a coextensive surface
layer (c) formed from a polymer selected from at least one of the group consisting of
ethylene-propylene-butene-1 terpolymer, ethylene-propylene random copolymer,
ethylene-propylene block copolymer, isotactic polypropylene, low density polyethylene
(LDPE), very low density polyethylene (VLDPE), linear low density polyethylene (LLDPE),
medium density polyethylene (MDPE), said polymer being compounded with i) an
effective amount of a coefficient of friction reducing, anti-blocking amount of anti-blocking
agent comprising a particulate cross-linked hydrocarbyl-substituted polysiloxane and ii) a
quantity of silicone oil such that a coefficient of friction-reducing amount will be present
on an exposed surface of layer (c) as well an exposed surface of layer (a) after mutual
contact of said surfaces; and
