Abstract
An aqueous barrier coating composition in the form of a dispersion includes: (a) water; (b) a polyester matrix polymer; (c) a platy to hyperplaty kaolin filler having an average shape factor of at least about 40:1, the composition being further characterized in that: (i) the composition has a solids content of from more than 20 weight percent up to 70 percent by weight; (ii) the composition has a weight ratio of polyester matrix polymer:kaolin filler of from 4:1 to 0.75:1; and (iii) a film formed from the composition exhibits at least 5-fold reduction in oxygen permeability as compared with a like film formed of said polyester matrix polymer. Also disclosed are barrier coatings derived from the compositions as well as packaging composites incorporating a barrier film formed from the compositions.
