Claim 42:
43. Method of making a recyclable paper barrier laminate of claim 1 comprising:
a) applying a first aqueous solution of a water-soluble polymeric composition onto the inner surface of the recyclable paper layer
b) removing the water from the first aqueous solution of a water-soluble polymeric composition to obtain a first water-soluble polymeric layer
c) applying an aqueous dispersion of hydrophilic nanoplatelets onto the inner surface of the first water-soluble polymeric layer
d) removing the water from the aqueous dispersion of hydrophilic nanoplatelets to obtain a water-dispersible barrier layer
e) applying a second aqueous solution of a water-soluble polymeric composition onto the inner surface of the recyclable paper layer
f) removing the water from the second aqueous solution of a water-soluble polymeric composition to obtain a second water-soluble polymeric layer.
