Appeal No. 1997-3906
Application No. 08/233,482
being drawn to a nonelected invention.
The subject matter on appeal relates to a process for the
low-temperature extrusion coating of a substrate with a
polyethylene film. The process comprises applying a
composition to the substrate by extrusion coating at a
temperature in the range of 175E up to 290EC. The composition
comprises a polyethylene component having a melt index in the
range of about 10 up to 100 dg per minute at 190EC and having
a sufficiently broad molecular weight distribution so that the
resulting composition is capable of being extrusion coated at
a temperature in the range of 175EC up to 290EC. This
composition also includes a hydrocarbon tackifying resin and a
thermally sensitive, hygroscopic or hydrophilic additive.
Further details of this appealed subject matter are set forth
in illustrative independent claim 12 , a copy of which taken 1
from the appellants’ brief is appended to this decision.
The following references are relied upon by the examiner
1In clause (c) of claim 12 and claim 25, it appears that
“190EC” is a typographical error which should read --290EC--
as reflected by the amendments filed November 30, 1992 and
January 21, 1992 in parent application Serial No. 07/681,801.
This apparent error should be verified and if necessary
corrected in any further prosecution that may occur.
