The invention pertains to a process for producing decomposable thin-walled molded articles such as cups, plates, fast-food packaging, trays, flat sheets and the like, applying a starch-based baking material on the lower part of a multipart, preferably two-part mold, wherein a tough, durable article of high mechanical stability is produced by using an essentially fat-free baking material that is made from water, one or more starches, starch products and/or flour or flour mixtures, a parting agent, that is one or more medium- or long-chain, possibly substituted fatty acids and/or their salts and/or their acid derivatives, e.g. acid amide, and/or a polymethylhydrogen siloxane and possibly thickening agents such as swelling starch, starch made pasty beforehand or baking leavings, and/or guar powder, pectin, carob seed meal, carboxymethylcellulose and/or gum arabic; fibrous materials, nonfibrous fillers and common additives, with baking the baking material filling out the mold, and by conditioning the resulting product to establish a moisture content of 6-22 wt %, characterized in that the baking material contains 45.0-68.5 wt %, preferably 48.0-65.0 wt % water; 11.4-45 wt %, preferably 15-40 wt % starch or starch product; 0.05-11 wt %, preferably 0.1-4.2 wt % parting agent, and 1.0-17.5 wt %, preferably 2-16 wt % hydrophilic vegetable fiber, such as cellulose, hemicellulose, potato fiber, beet chips and the like, the powdered fiber being premixed dry with the parting agent. |
