摘要： 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.

摘要： The present disclosure describes acyl halide liquid dispersions and tunable methods of treating cellulosic materials with compositions that provide increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for reacting acyl halides with and binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.

摘要： The present disclosure describes methods of treating fibrous cellulosic materials with sucrose fatty acid ester containing particles (carrier systems) that allow for modifications of surfaces, including making such surfaces water resistance and/or oil/grease resistance. The methods as disclosed provide combining at least one saccharide fatty acid esters (SFAE) with a polymer (e.g., latexes) to form micellular particles and applying such particles to substrates including fibrous cellulose-based materials (e.g., pulp) to form, inter alia, molded products. Compositions comprising combinations of SFAE, a latex and optionally a mineral or other additives are also disclosed.

摘要： The present disclosure relates generally to methods of treating cellulosic or synthetic materials to provide new and/or improved properties, such as water resistance and oil/grease resistance (also referred to as lipophobic and hydrophobic barrier properties), separately or in combination, by using bio-based coatings and/or compositions containing blends of glycerides and/or fatty acid salts, and products obtained by the methods.

摘要： The present disclosure describes aqueous adhesives comprising, inter alia, adhesives and saccharide fatty acid esters, particularly unsaturated fatty acid esters (uSFAE), including aqueous adhesive compositions containing such a combination and where such aqueous adhesive compositions show improved water resistance compared to adhesives which do not contain said uSFAE. Articles of manufacture comprising said aqueous adhesive compositions are also described.

摘要： The present invention describes tunable methods of treating cellulosic materials with a barrier coating comprising at least two polyol and/or saccharide fatty acid ester that provides increased water, oil and grease resistance to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for adhering of the barrier coating on articles including articles comprising cellulosic materials and articles made by such methods. The materials thus treated display higher hydrophobicity and lipophobicity and may be used in any application where such features are desired.

摘要： The present disclosure describes methods of treating cellulosic materials with compositions that allow greater retention of inorganic particles on cellulosic substrates. The methods as disclosed provide combining saccharide fatty acid esters (SFAE) with such inorganic particles and applying such combinations on cellulosic materials to eliminate or reduce the use of retention aids or binders for filler in the paper making process. Compositions comprising such combinations of SFAE and inorganic particles are also disclosed.

摘要： The present invention describes methods of treating cellulosic materials with a composition comprising hemicellulose and/or lignin and sucrose fatty acid esters to modify barrier functions of such materials. The methods as disclosed use hemicellulose or lignin combined with saccharide fatty acid esters to form films on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated exhibit more effective barrier functions, and mechanical properties, and may be used in any application where such features are desired.

摘要： The present disclosure describes a method to modify dried polymer films using printed crosslinking agents, including that the crosslinked polymer resulting from the method exhibits greater insolubility compared to crosslinked polymers made where the crosslinking agent and the polymer are combined and applied as a homogenous solution. Articles of manufacture generated by such a method are also disclosed.
