ABSTRACT:
Disclosed is a gas barrier coating and multilayer packaging materials made therefrom. The gas barrier coating includes a polyamine (A), a polyepoxide (B), and a filler (C). Polyamine (A) includes at least one of the following: (a) an initial polyamine, and (b) an ungelled polyamine adduct which is the reaction product of the initial polyamine and epichlorohydrin and/or a polyepoxide having a plurality of glycidyl groups linked to an aromatic member. Polyepoxide (B) includes a polyepoxide having a plurality of glycidyl groups linked to an aromatic member. Filler (C) includes a platelet-type filler with the following particle size distribution: (a) a number mean particle diameter in the range from about 5.5 to about 15 microns, and (b) a volume mean particle diameter in the range from about 8 to about 25 microns. In addition, the present invention provides glossy, multilayer packaging materials containing an oxygen barrier material layer having an oxygen permeability constant not more than 0.05 in cubic centimeter-mil/100 square inches/atmosphere/day at 30.degree. C. and 50% R.H. The glossy, multilayer packaging material includes: (a) at least one layer of a substrate material, and (b) at least one layer of the gas barrier material described above.
