Process for manufacturing compostible thin-walled molded articles based on starch

A process of manufacturing biodegradable, thin-walled baked shaped bodies in a multi-part baking mold, comprising the steps of

• (a) baking an essentially fat-free baking composition in the mold, the baking composition being composed of
• (1) 42.0-60.0%, by weight, of water,
• (2) 36.0-56.5%, by weight, of a starch product comprised of 0.0-54.5%, by weight, of a first starch base selected from at least one member of the group consisting of starch, various starches, a mixture of various starches, flour, various flours and a mixture of various flours, and 2.0-56.5%, by weight, of a second starch product selected from at least one member of the group consisting of a starch esterified with organic acids, a starch esterified with phosphoric acid, an etherified starch, a cross-linked starch and a starch modified by ionic interaction with an added salt,
• (3) 0.04-11%, by weight, of a release agent selected from at least one member of the group consisting of medium-chain and long-chain fatty acids and their salts, derivatives and amides, medium-chain and long-chain substituted fatty acids and their salts, derivatives and amides, and 0.5-6.5, by weight, of polymethylhydrogen siloxanes,
• (4) fibrous materials,
• (5) non-fibrous fillers,
• (6) colorants,
• (7) preservatives, and
• (8) antioxidants, and
• (b) conditioning the baked shaped bodies after baking to obtain a moisture content of 6-22%, by weight.
