Abstract
Disclosed herein are coated articles comprising a substrate having at least one surface, and a coating composition disposed in a substantially continuous layer on at least one surface of the substrate, wherein the coating composition is present in an amount sufficient to increase the oxygen barrier property of the substrate, and the coating composition comprises a polysaccharide derivative. The polysaccharide derivative can comprise a poly alpha-1,3-glucan ether compound, such as a quaternary ammonium alpha-1,3-glucan ether. Also disclosed is packaging comprising the coated article.
Claims16
A coated article comprising:
- a substrate having at least one surface;
- and
- a coating composition disposed in a substantially continuous layer on said at least one surface of the substrate, wherein the coating composition is present in an amount sufficient to increase the oxygen barrier property of the substrate, and the coating composition comprises a polysaccharide derivative poly alpha-1,3-glucan ether compound represented by the structure:
- wherein
- (i) n is at least 6,
- (ii) each R is independently an H or organic group, and
- (iii) the compound has a degree of substitution of about 0.05 to about 3.0.
