Appeal 2007-1906
Application 11/127,887
Appellant presents an invention directed to a polymeric film that is
conformable and useable as a facestock (Specification 4:2-6). The facestock
is disclosed as being capable of accepting a holographic layer. Id. The
facestock is such that the resulting holographic image suffers little cracking
or flaking when employed as part of a label. Id. Claims 1 and 26, which are
directed to a machine direction oriented polymeric film are illustrative and
reproduced below:
1. A machine direction oriented only monolayer film
comprising
(A) at least one proplylene copolymer having a melt
flow rate of at least about 4 g/10 min., and
(B) at least one polyethylene,
wherein the film has been oriented by stretching in the machine
direction at a stretch ratio of about 2:1 to about 9:1 and then heat set
or annealed to provide dimensional stability.
26. A machine direction only oriented multilayer film
comprising
(A) a base layer having an upper surface and a lower
surface, and comprising polyethylene, a propylene homopolymer, a
propylene copolymer, or a blend of a propylene homopolymer and a
propylene copolymer, and
(B) a first skin layer comprising a blend of
(B-1) at least one propylene homopolymer or
propylene copolymer, and
(B-2) at least one polyethylene wherein said skin
layer overlies the upper surface of the base layer, and
