Abstract:
A method for producing disposable, thin-walled molded articles comprising:providing a multi-part mold having a lower mold member;preparing a starch-based baking composition which includes a starch component, water at a proportion of about 100% to about 360% by weight, relative to the starch component, and a release agent, wherein the starch component is at least one of starch, a starch mixture, flour, a flour mixture, and a starch derivative;adding polyvinyl alcohol in a quantity of about 0.5% to about 40% by weight, relative to the starch component, to the baking composition, wherein the polyvinyl alcohol has a degree of polymerization of over 1000;introducing the starch-based baking composition into the lower mold member;baking the baking composition within the multi-part mold to remove sufficient water by evaporation so as to substantially solidify the starch-based baking composition; andremoving the substantially solidified starch-based composition from the mold and conditioning it to a moisture content of about 6% by weight to about 22% by weight.
