| abstract |
Compositions of the invention include a hydroxy-functional polyester and a natural polymer. Articles can be made from such a composition so as to have sufficiently strong tensile strengths as to form disposable utensils or to have sufficient stretchability so as to form thin wrap films. However, the compositions are more environmentally friendly than commodity plastics such as polyethylene or polystyrene. Granular starches derived from a grain, a root, a legume, or mixtures thereof, are particularly preferred as the natural polymers for inclusion in the compositions. |
