Abstract
Barrier coating mixtures contain in a carrier liquid, (a) a non-elastomeric polymer; (b) an exfoliated layered platelet-like silicate filler which may or may not have been acid or base treated that has not been functionalized with organic cations having an aspect ratio greater than 25; and (c) at least one additive, wherein the total solids content is less than 30% and the amount of filler is between 5% to about 60% of the total solids content. Coated articles and containers, freestanding films and packaging films are produced using the barrier coating mixtures. Methods of manufacturing such coated products are also encompassed.
