A multiple layer film useful in moisture barrier packaging applications has
at least one layer comprising a blend of propylene polymer or copolymer,
and a hydrocarbon resin; and two additional layers comprising a propylene
polymer or copolymer, ethylene alpha olefin copolymer, ionomer,
polybutene, or blends thereof. A core layer of ethylene vinyl alcohol
copolymer or other oxygen barrier material, or high density polyethylene,
can be included in some embodiments. A preferred embodiment of the
multi-layer film exhibits excellent moisture barrier and optical
properties, and shrink properties as well if the film has been oriented.
High oxygen barrier is also a feature in embodiments including EVOH or
other oxygen barrier materials.
