Application No. 09/775,451
outside surface. This lower coefficient of friction for the
inside surface facilitates the placement of articles such as
furniture inside the bag. Further details concerning this
appealed subject matter are set forth in representative
independent claims 1 and 18 which read as follows:
1. A bag formed of a dual surface material wherein said dual
surface material comprises:
a. an inside surface having a coefficient of friction range
of approximately 0.125 to 0.275; and
b. an outside surface having a coefficient of friction
range of approximately 0.300 to 0.600.
18. A bag formed of a dual surface material wherein said dual
surface material comprises:
a. an outer polymer film layer having a coefficient of
friction range of approximately 0.300 to 0.600; and
b. an inner polymer film layer having a coefficient of
friction less than said outer layer.
The reference set forth below is relied upon by the examiner
as evidence of obviousness:
