Abstract
The starch-based polymers exhibited shear thinning and elastic nature in rheological characterizations. Thin coatings with narrow neck-in could be produced at fairly high extrusion coating line speeds. Adhesion between the starch-based polymers and paperboard was typically weak. Water vapor barrier of starches was very poor. Soft starch grades had a good pinhole resistance and a good heat sealing performance. Brittle nature of starch caused cracking as the coated paperboards were creased.
