    摘要: 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.

    摘要: 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.
