ABSTRACT:
A card sheet including a top material layer having pre-cut weakened lines extending partially but not completely through the top material layer, the top material layer having a front side and a back side; and a starch composition layer applied to the back side of the top material layer, wherein at least a portion of the starch composition diffuses into the top material layer to a depth and renders the top material layer breakable along the weakened lines. A method of making the card sheet, including providing the top material layer, cutting partially through the top material layer; and applying a starch composition to form the starch composition layer on the back side of the top material layer; and at least partially removing any diluent present in the starch composition. The top material layer may be printable, and the card sheet may include a second top material layer.
