Abstract
The present disclosure describes methods of treating cellulosic materials with barrier coating compositions that allow for modifications of surfaces, including making such surfaces exhibit barrier functions such as oil and grease resistance, water resistance and the like. The methods as disclosed provide combining at least one saccharide fatty acid ester (SFAE) with polymers and applying such combinations on substrates including cellulose-based materials. Compositions comprising combinations of SFAE and polymers are also disclosed, including the use of such compositions to reduce blocking effects of said polymers without affecting the barrier performance or folding of articles of manufacture coated with said compositions. In addition, blocking ratings data for SFAE-polymer compositions may be used to identify conditions under which adhesive properties may be exploited to produce compositions that allow for effective heat sealing of articles of manufacture.
