Effect of glycerol and coating weight on functional properties of biopolymer-coated paper

► Properties of coated papers are influenced by glycerol concentration and coating weight. ► Coating weight factor decreases water vapor permeability. ► Water vapor permeability is lowest for sodium caseinate-coated paper. ► Glycerol concentration has a positive influence on elongation values. ► Optimization of responses is performed by desirability function method.
