foil and on both sides of the barrier layer at least one functional layer. Claim
38, which is representative of the claimed invention, appears below:
38. A sterilizable composite film containing a barrier layer
that is impermeable to water vapor and gases comprising a metal
foil and on both sides of the barrier layer at least one functional
layer, the composite film having a layer structure containing one
on top of the other in the following sequence:
(a) a first functional layer containing a plastic film that is a
polyester, a polyamide, or a polyolefin, or an extrusion layer of a
polyolefin, or one or more lacquer layers, or print and lacquer
layers, or print layers;
(b) a metal foil having a thickness of 5 to 100 pm; and
(c) a second functional layer containing a plastic layer that
is a layer comprising a coextrusion-coated, a coextruded, and/or
an extrusion-laminated film having a sequence of a first
polypropylene layer, a polyamide layer, and a second
polypropylene layer, said first polypropylene is directly bonded to
metal foil (b) or is bonded to metal foil (b) by means of a bonding
agent layer or a laminate adhesive layer, and, optionally, a primer
layer is on at least one surface of metal foil (b).
The Examiner rejected claims 38-43 as anticipated by Breitler. Claim 38
is directed to a sterilizable composite film containing a barrier layer that is
impermeable to water vapor and gases comprising a metal foil and on both
sides of the barrier layer at least one functional layer. The composite film has
a layer structure containing layers one on top of the other in a specific
sequence.
